Chapter One – Introduction

1.1 Summary of the topic

Increasingly, the topic of health has become more and more eminent in our

society and daily lives. Today, jargons include healthy beings, balanced life,

good diet and healthy city are frequently used everywhere. This phenomenon is

a shift from the legacy of consumerism and materialism, where the focus, more

or less, is about consuming and consuming more. As such, we mould our

physical environment accordingly, consuming more resources and land of the

earth. Hence, we build and erase paying little attention to the externalities that

may be affected. As time passes, evidences have shown such behaviour will

eventually affects us and the longevity of our survival. This is when we begin a

new chapter of legacy – healthy city.

Walking is a hot topic in the agenda of healthy city as it by itself is a transport

mode, and virtually cost nothing. Arguably, walking can yield benefits

environmentally, economically and socially. This thesis is not advocating people

to destroy their cars once and for all and revive walking as the mean to get to

places, like in the medieval time. Such would cost too much time and cost

considered the size and layout of our modern city today. As such, in today’s

world, it is considered that walking is only viable if it is combined with a fast

transport mode, which should also be environmental-friendly. An example of this

is walking and getting on commuter railway, which is very fast compared with a

number of public transports available in New South Wales. In actual fact,

walking as an inter-mode to a public transport station constitute the largest

proportion of walking trips t in Sydney in the year 1991 and 2001, according to a

joint study by Transport Population Data Centre, NSW Department of

Activity and Health (2005).

Walk trips by purpose on an average weekday (Corpuz, Hay & Merom 2005)

This thesis envisages gaining insights on walking as an intermodal transport. In

the realm of town planning, understanding the influence of the built and natural

environment has on people making their choice to walk to a public transport

station is crucial in the process of city making. Railway stations are examined in

this instance. Investigation will be carried out to find out the optimum walking

distance to a train station and the strength of the relationship between the

physical environments and walking distance. The results will be a hope for

creating a better city for tomorrow - one that invites walking and the use of

public transport, thus helping people to become more active.

1.2 Importance of topic

Hardly anybody dwell into the nexus of walking and public transport, yet walking

and public transport have frequently been interlinked in health and planning

literatures without more sophisticated analysis. Evidence of such negligence can

be seen from a statement which was found in the design guideline published by

the Heart Foundation of Australia (2004):

“Planners play an essential role in planning, designing and regulating the

environments in which we live. Well planned neighbourhoods can increase the

number of people who walk to…facilities and public transport.”

However, how it can be achieved exactly has not really been uncovered. To

make such to become a reality require understanding and recognising walking

as a mode before any designing to take place. Understanding the matter helps

planners make cities and towns that are encouraging to walk, especially to train

stations. It is important to increase that understanding in the any context. The

matter is urgent at present as the majority of the population are still choosing to

travel on their automobiles for their normal daily trips, causing damages to the

already deteriorating environment.

Proportion of trips by mode and age group on an average weekday 1999 and 2006

(Transport Data Centre 2008)

The findings from the 2006 household travel survey, recorded by the Transport

Data Centre (2008), show that automobile still dominates all category of travel

by a majority in the year 1999 and 2006. This is in spite of age differences. Private

vehicle travel accounted for over 50% of total travel in both 1999 and 2006 and

across all age groups. Our reliance on private vehicular transport has been

increasing rather than decreasing during this six year period from 1999 to 2006.

During the same period, public transport usage had decreased slightly across all

age groups except in the age group of 21-30.

We cannot afford a further drop in public transport patronage and further

increase of automobile usage as the statistics have shown no sign of reversing

travel pattern. Planning our cities and towns that are transit oriented is believed

to have significant impact on the propensity to walk and how far they walk.

Such strategy is very important to be examined as numerous studies have shown

people living far from a public transport stop are highly likely to travel with their

automobile instead of choosing to walk to get to the public transport stop. This is

illustrated in the next diagram.

(Belden Russonello & Stewart Research and Communication 2004)

According to Belden Russonello & Stewart 2004, the general American

communities are concerned about the walking distance to public transport

station. It is ranked just after the issues of housing for low incomes. This study

further hints the need for better understanding of what really is the optimum

walking distance that people will walk to get to the transport stop. This thesis

addresses this very issue by examining the theoretic walking distance suggested

by scholars and the walking distance that people will more likely to walk in a

quantitative research conducted. The results will be important for transport and

urban planning. It is envisaged that the results will help planners and politicians

to make decisions that will ultimately reduce the necessity of private vehicular

travel in cities.

1.3 Specific of topic

The term ‘ped-shed’ refers to the walkable catchment within an actual area to

which people are very likely to walk to get to a centre. Studies have found that

the acceptable ped-shed for any centre to be 5 min walking distance and 10

min for major transport stop such as railway station. This is the generally

accepted figure adopted both in Australia and the United States. This finding is

important as it has implications on transport and land use planning. However,

there are other researches which suggested other figures.

According to a U.S. Smart Growth Agency (2008), it was reported that, in

general circumstances, most Americans are willing to walk up to about 150

metres, 40% would walk 300 metres and only a dreadful 10% would walk a

distance of 800 metres.

For intermodal walking, the 1996 National Personal Transportation Study (Smart

Growth 2008) showed that only around 10% of residents living within 400 metres

of a public transport stop used it to get to work and the figure drops to 3.8% for

those living between 400 to 2000 metres, indicating probably less than 3.8% used

the public transport in the distances between 400 and 800 metres from the

transport stop. This is opposed to Pushkarev and Zupan’s remark (1980) of

walking distance of 800 metres as the rail catchment.

Different researchers from different places would have different view on the

actual figures. For example, Goodman and Tolley (in Tolley 2003) have shown

that acceptable walking distance of up to 1.6 km and in some circumstances

71

Page 7: Chapter One – Introduction · 2013-04-11 · Chapter One – Introduction . 1.1 Summary of the topic . Increasingly, the topic of health has become more and more eminent in our

up to 2 km. This extended walking distance figure has been proven true in some

European cities.

While different researches have different figures, the New South Wales

Government has more or less adopted figures similar to the researches from the

America. This could be due to similarity of our urban landscape setting – one

that is vast and extremely auto-oriented. Figures can be seen from the planning

guideline published by the Department of Planning (2004), where we see the

NSW government adopting a circle of radius 400 metres or 5 minute walk

around a centre and 800 metres or 10 minute walk around a public transport

stop to be walkable.

Besides having a walkable figure, our Government also advocates good

environment will induce more walk trips. The NSW Premier’s Council for Active

Living (2008) believed that “design considerations have the potential to

positively impact individual and community health and wellbeing”. Design

considerations include mixed use, higher densities, walking routes and attractive

environment. This is also emphasized by Health Foundation of Australia, in a

design guideline which they received an award for in 2004. However, again,

both have been advocating design as a factor but not giving insights as to how

potent and effective good environment could influence people choosing to

walk.

Despite statistically differences on an optimum walking distance, some

researches concluded with remarks that the physical characteristics of the

environment would have significant impact on walking behaviour. Those

characteristics can fall into density, diversity and design categorically. Careful

considerations of these components will make up an environment that most

people will walk and for a longer distance.

If the environment is to be proven significant in whether people choose to walk,

then planners have the responsibility to shape the towns and cities in such

fashion that will encourage us all to walk. This will be explored in more detailed

in Chapter 2.

1.4 Hypotheses

There will be three main categorical hypotheses in this thesis, namely density,

diversity and design.

Density hypothesis - The higher the residential density, the more likely a

person will walk for longer distance

The higher the residential density means that more people will be on the street,

making the streetscape more celebrated and vibrant. More people on the

street allow the streetscape to be less homogeneity and feel safer. The

relationship is exploded in Chapter 2.

Diversity hypothesis - The more satisfactory the level of mixed use, he/she will

walk for longer distance

Mix use refers to the diversity of function a place can serve. Commonly refers to

the mixing of retail/commercial/services with or in proximity to residential

development. This will be discussed further in Chapter 2.

Design - The better the aesthetic of the place and street connectivity, the

longer a person will walk

Most of us would want to travel as directly as possible and seeing things that are

aesthetically pleasing. The different aspects of design will be explained in

detailed in Chapter 2.

The results will show how significance these environmental variables are to how

far they walk and provide a comparison to the figures disclose from different

literatures and government agencies. Some socioeconomic details will also be

gathered for analysis, however, these variables will not be analysed to the

extent of the environmental variables.

1.5 Layout of thesis

The chapters that follow are the results of the much research and analysis

carried out to determine if the hypotheses are correct. Chapter 2 is the

examination of past literature. Chapter 3 looks at the methods that were

considered and used for this research. Chapter 4 outlines the results found from

the primary data that was collected. Chapter 5 discusses the results. Chapter 6

seeks to promote another form of urban landscape by providing examples.

Chapter 7 concludes this thesis with a reflection on the topic.

Chapter Two – Literature Review

2.1 The Rise and Dawn of Automobile

Since automobile was invented in the 1880’s, it has become increasingly

popular for over a century. The automobile outlasted the Great Depression in

the 1930’s and two World Wars. However, not only the automobile did not fade

away, it became even more appealing and effective to use as the cost of

owning one dropped. Eventually, it became a product some people see as a

necessity rather than luxury. Specialization of towns and suburbs in our cities only

made automobile more appealing.

After a century, people are starting to realise the adversaries that the

automobile is causing us. The realisation was mainly induced by the vast number

of literatures opposing its further use. Some called for significant cut for its use,

while some suggested an end to it to cease the great damage it is causing the

environment. This chapter will provide some background knowledge to the

impact automobile had caused in different aspects and the reasons to find

alternative mode of travel in modern cities. This knowledge will help us to

understand the rationale to revive walking as some means of transport

Europe, a continent about the same size of Australia, is the origin where most of

the early settlers of Australia came from. Australia and Europe shared a lot of

commonalities in the past and present, yet in terms of transport planning,

Europeans leap a big gap ahead of Australia. This is evident when comparing

transport statistics from Australian cities with European cities. According to

Newman (1992), Australians consumed gasoline three times more, use less

transport, four times less walking and cycling, over 50% more parking our city

cores and four times less dense urban form than the European cities. These

results provided crucial indication about how Australian cities performed in

targeting automobile use. The differences show that although our cities are

considered as developed cities, we definitely are not one in terms of

transportation.

Proportion of trips by mode on average weekday (Transport Data Centre 2008)

In the graph above, we see evidence of automobile being the most dominating

transport mode (‘Total Vehicle’) from 1991 to 2006 in Sydney. A percentage of

70.1 was recorded in the year 2001, an increase of 3.2% from 1991 and then

dropped slightly to 69.5% in the year 2006, an increase of 2.6% from 1991. This

increase occurred in spite of rising concerns of automobile from around the

world.

Australian cities will soon have to bear the costs for the increased automobile

usage. There have been studies on the economic, environmental and social

costs that automobile brought to us. These costs are translated in the following

table.

Many, including planners, still do not understand the full extent of the

implications of automobile use. The economic, environmental and social

impacts that automobile causes, as indicated, are enormous. Like early in the

twentieth century, interconnection was made between public health and urban

planning as heavy industries affect public health, we urgently need today to

draw the same connection only that this time it is the automobile. This

connection was translated to the healthy city initiatives in which part of it fosters

walkable neighbourhood and public transport. Walking has been mentioned in

the initiatives as a mean to reduce automobile uses. In the next chapter, we

look into the fundamentals of walk as a transport mode.

2.2 Walking – popular and unpopular

“Walking is the most natural form of physical activity and our most basic mode

of transport. A comprehensive review of the subject by the originator of the

exercise/health relationship concluded that ‘walking is the nearest activity to

perfect exercise’”. (Cavill in Tolley 2003)

Walking is healthy and we all walk. Any trip by any means includes at least a

small distance covered on foot at the beginning and end of each journey.

Walking is the most basic urban transport mode that has allowed cities to

operate. However, its role has been eroded with the introduction of mechanical

means of transportation, especially in the Australian and American communities.

Evidence of this can be found in the negative trend in the percentage of

people who walk to their destinations in Sydney presented below:

Year Growth 2004 – 05 - 0.9% 2005 – 06 - 1.7%

We look in turn some of the possible limits of walking that may have led to the

negative trend. A benefits and limits table is listed below:

Benefits and Limits of Walking

Benefits Limits

The walking mode involves very little

expense, either public or private.

Human does become tired, rather

quickly. Studies shows acceptable

foot is 400m.

basic form of exercise

Speed: For short distances, the slow

pedestrian speed does not matter, but

it becomes a factor with longer trips.

Availability: The mode is always present

and ready for use (within reason).

Adverse weather will reduce

considerably any propensity for

walking.

Certainty: A pedestrian is in direct

contact with the surrounding

environment so are others nearby.

Pedestrians have limitations including

how much weight they are able or

willing to carry with them.

2.3 Density – Diversity – Design (3Ds)

We now look into the core of the subject. Density, diversity and design were said

to influence people choosing to walk. A broader study of walking and the

environment was examined. The connection between the physical environment

and walking was found to be widely accepted from scholars and government

agencies which will be examined later in the text. Many of the studies

concluded that the physical environment had significant influence on people

who chose to walk.

An environment that encourages walking have characteristics including higher

residential density, mixture of land uses and connected streets (Brownson et al.

2003). Such concept coincides with other studies like Saelens’s (2003), who

suggested similar elements in his study but added short block lengths was also

important for people when deciding to walk especially for those walking for

transportation. He also suggested that low walkability can be defined by low

residential density, lack of mixed land uses and poor street connectivity. The

definition certainly gave heavy weighting to urban planning in the arena of

walking.

The phenomena later went further with Lee and Vernex (2006) remarks. They

stated in their study that “architectural visual quality showed significant bivariate

association with walking.” Other than visual quality, they also were in support of

the elements mentioned were significant for people who chose to walk in their

study.

Another advocate of the concept was Giles-Corti, a professor from Western

Australia. In a quote in the following, it is evident that he made the presumptions

that such concept was right.

71  Page 15 

 

   

Page 16: Chapter One – Introduction · 2013-04-11 · Chapter One – Introduction . 1.1 Summary of the topic . Increasingly, the topic of health has become more and more eminent in our

“There is strong evidence that the built environment affects the transport mode

choices of both adults and children. A growing body of evidence confirms that

neighbourhoods characterised by low density, poorly connected street

networks, and poor access to shops and services, are associated with low levels

of walking. Moreover, urban sprawl and low walkability appeas to be

associated with obesity. This may be due to long commuter trips to reach

suburbs located on the urban fringe.” (Giles-Corti 2006)

In her studies, she concluded that “cross sectional studies repeatedly show that

residents in more walkable neighbourhoods do more transportation related

physical activity including walking.” (Giles Corti et al. 2007)

Engagement of the topic went on further to organisations and even

government agencies. The concept became a belief for the Heart Foundation

of Australia. The Foundation published a guideline in 2004 called ‘Healthy by

design: A planners’ guide to environments for active living’. This is an initiative by

the Foundation to promote design principles that coincide with the belief

mentioned and it sees those principles as solutions to many issues including

walking to public transport. This is evident in a quote which says “Planners play

an essential role in planning, designing and regulating the environments in

which we live. Well-planned neighbourhood can increase the number of

people walk walk or cycle to shops, parks, services, facilities and public transport.

This supports healthier lifestyles for local residents, a more socially vibrant local

neighbourhood and brings with it associated economic and environmental

benefits.” (Heart Foundation 2004)

2.3.1 Density

Essentially, this is about raising residential densities in a neighbourhood. Ewing

(1996) explained, the higher the density, especially around a transit stop or

station, the more residents will be within proximity of the transit stop or station,

71  Page 16 

 

   

Page 17: Chapter One – Introduction · 2013-04-11 · Chapter One – Introduction . 1.1 Summary of the topic . Increasingly, the topic of health has become more and more eminent in our

which will then improve people walk and riding public transport. The side

impacts, he added, is a more vibrant and secured street life, which will bring

more people to walk.

(Denver Regional Council of Gov. 1993 in Ewing 1996)

The above graph shows the analogy that more people, employees in this case,

meant more walk and ride trips. He claimed that low density would not have

been practical without automobile to cover great distance for daily activities.

Hence, the wisdom of higher densities is that it would compress activities into a

small area which allow people to walk, instead of driving, to almost everything

within reasonable distance. The connection between high residential densities

and lower automobile use is endorsed very much in Sydney. This is evident in the

table below adopted from the RTA.

Development Type Weekday peak hour trips Daily vehicle trips Residential type

Dwelling houses 0.6 to 0.85 per dwelling 6 to 9 per dwelling

Medium density units 0.4 0.5 per dwelling 4 to 5 per dwelling

High density units

- Near CBD, busy locations

- Less built up areas

0.24 per dwelling

0.29 per dwelling

2.5 per dwelling

3 per dwelling

Page 18: Chapter One – Introduction · 2013-04-11 · Chapter One – Introduction . 1.1 Summary of the topic . Increasingly, the topic of health has become more and more eminent in our

(RTA in South Sydney City Council 1996)

In the table, it is apparent that lower densities housing produces fewer weekday

peak hour trips and daily vehicle trips. The difference of automobile use

between dwelling houses and high density units was almost tripled.

This connection was also carried internationally by people like, Hass Klau, from

Environmental and Transport Planning in the U.K., who gave examples in the

Amsterdam that more people walked in the densely populated parts than those

lived in less dense housing or modern housing estates, which are auto oriented.

She suggested that there is a relationship between population density and

walking. Her conclusion (Hass Klau in Tolley 2003) was “people living in densely

populated areas are much more reliant on walking than households residing in

the suburban or rural regions.”

2.3.2 Diversity

The presence of retail uses can yield almost as many transportation benefits as

higher densities in residential neighbourhoods (Bernick & Cevero 1997). As Ewing

(1996) justified, with the rise of the automobile, almost all of our daily essentials

have become compartmentalized and at various places. Where we live, work

and play are remote form one another, and beyond walking distance of a

suburban home. Mix use, therefore, is considered to be a necessary

precondition for pedestrian street activity of a place as, simply, there are places

to go within reasonable walking distance. Ewing (1996) made remarks that

“transit ridership should grow as land uses become more varied and

integrated.”

In New South Wales, the Department of Planning (then DIPNR in 2004), was also

a fan of such connection. In a planning guideline published in 2004, it states,

“Mixing land uses in and around accessible centres creates opportunities for

people to live near shops, public transport and other services, making them

more accessible by walking rather than by car… This can be enhanced by

ensuring all compatible neighbourhood activities are co-located within or near

the neighbourhood centre.” (DIPNR 2004)

Cluster of uses reduces walking distance (DIPNR 2004)

With that analogy in mind, the more mix use the greater possibility of people

walking in a neighbourhood as there are more places to go and drop-by at

midst of a trip. It is fair to conclude, accordingly, that more mix uses in a

neighbourhood and around a transit station would encourage people to walk

to destinations including the transit station.

2.3.3 Design

Traditional city layout with inter connected street network is an important factor

in influencing people to walk. Traditional cities featured by nodes of

development on streets that connects to other places of interest in the area, a

cluster of mix uses and activities that are often in the form of medium to high

density (Jones in Tolley 2003). The city is focused on the pedestrian and the

convenience of pedestrian movement. A typical European city, like the centre

of Copenhagen is an example of that.

Jones (in Tolley 2003) also pointed out that there is another form of urban design

which we have adopted now in western societies, known as suburban

development. Suburban development is largely different from the city layout of

a traditional city. Roads are curvilinear with cul-de-sacs. It promotes hierarchy

based road system and specialisation of land uses in different districts. Suburban

urban layout encourages automobile movement and centred on provision of

car parking rather than accommodation of pedestrian.

Typical suburban development layout

A more traditional neighbourhood layout

(Jones in Tolley 2003)

Studies have shown many advantages with the traditional neighbourhood

layout including more direct routes, alternatives to high volume routes and sense

of orientation as vision is clear in a grid layout. Ewing (1996) also stated that the

traditional grid layout has already been actively promoted in many transit

oriented development to capture more people walking and public transport

ridership as a grid layout provides direct access to a transit stop or station.

In a guideline published by the Department of Planning (then DIPNR) in 2004, the

department also agreed that “street pattern is an important determinant of

walkability”. The guideline then moves on to promote that “local streets should

be highly interconnected...[as it makes] walking trips short and direct...sightlines

are extended and several route options are available for any one trip.”Streets

are encouraged to orient to transit stop. Cul-de-sacs and other features of a

suburban development are not supported in the guidelines. It is clear that the

Department was in support of transit oriented development layout with street

connectivity similar to the traditional ones.

Walkable neighbourhood is fostered by connectivity

(DIPNR 2004)

Good street layout design is best to combined with some weather protection.

Canopies, awnings, and arcades are common urban design features. Ewing

(1996) suggested that such features would protect pedestrians as well as transit

walkers. Trees planted between the street and sidewalks provide a physical and

psychological barrier between large mass vehicles and small mass pedestrians

for visual relieve. Trees visually limit street space in architectural terms, at the

same time, decorate a street or act as a sceen on an unpleasant view. Streets

with either natural or built features to protect pedestrians from weather form

good design elements that promotes walking and for farther. An example of

such is the European city of Copenhagen.

The city of Copenhagen made its commitment to transit oriented development

in the 1960s. Part of the commitment involved in bringing walking and cycling

not only as travel alternatives but also as viable means of accessing train

stations. According to the initiative, involving improving pedestrian facilities and

turning roads into walking paths, urban designers in Copenhagen found that the

average number of people sitting and staying around public spaces and streets

rose from 1,750 in 1968 to 5,900 in 1995. A 1994 survey of access trips to 15

suburban stations in Copenhagen found that walking dominated for distances

up to 1 km from stations, capturing 38 to 100% of access trips (Bernick & Cevero

1997). According to the success in Copenhagen, it is expected that exclusive

walking paths, good pedestrian facilities and environment would induce more

people walking and for farther.

2.3.4 Safety

Safety is essential to all when deciding to choose walking or alternative transport.

Safe, nonthreatening environments need to be created so that people will be

willing to forego their motor vehicles in favour of alternative modes of travel.

Pedestrian pockets offer advantages over conventional suburban designs in

providing safer and more enjoyable non-automobile travel. The dangers of

motor vehicle travel are seldom considered when people elect to travel. The

feeling of safety that comes from being inside a vehicle is still reassuring to most

people. However, people can be reassured by proper space design, proper

lighting and closeness to others.

2.4 Transit Oriented Development

“A Transit oriented development is a mixed use community within an average

[400 metres] walking distance of a transit stop and core commercial area. The

design, configuration, and mix of uses emphasises a pedestrian oriented

environment and reinforce the use of public transportation. TODs mix residential,

retail, office, open space, and public uses within comfortable walking distance,

making it convenient for residents and employees to travel by transit and

walking.” (Calthorpe1990)

The terminologies used in transit oriented development, as defined by Calthorpe

(1990), shared many commonalities with what an ideal town looks like that

compatible with the 3Ds analogy. Calthorpe’s definition of the TOD is similar to

that of Greenwald (2003), Giles-Corti (2007) and Bernick & Cevero (1997), who

all put many emphasises on higher densities, more mixed uses and pedestrian

oriented design elements such as inter connected street form. As such, TODs are

the best examples in testing the 3Ds mentioned and their relevance to walking

to public transport. The selection will be further explained in Chapter 3.

Bernick and Cevero (1997), especially, concentrated his studies on people’s

willingness to walk in relation to a TOD environment. Through his studies, he

found that most Americans are willing to walk 150 metres, however, only 20% will

walk if the distance increased to 300 metres. The figure dropped to 10% for

distance of 800 metres. Despite the less than appealing results, he drew the

conclusion that “walking distances [can be stretched] through good quality

planning that lends legitimacy to transit village planning.”

(Belden Russonello & Stewart Research and Communication 2002)

As shown in the graph above, it is indicated that “things are too far and it is not

convenient to walk” made up the largest portion of those who were surveyed

with the question of the reasons for not walking more. As such, the notion of

what is the acceptable walking distance is important when people making the

decision to walk and is imperative for town planning such as planning for the

environment around a transit station. It is that notion together with the 3Ds that

will be tested.

Chapter Three - Methodology

As has been shown in Chapter One the aim of this research was to analyse

walking as intermodal to train stations. The focus of the investigation was to

investigate how long people walked to the selected train stations and whether

the physical environment influenced them to walk that distance at all. The

investigation was carried out with variables that are compatible to the 3Ds

concept.

Surveys were found in this research to be an appropriate tool as they allow for

primary data to be collected from train travellers in Sydney. Questions were

asked directly of those that used the train. These questions were aimed at

answering the hypotheses as set out precisely in Chapter One.

Information was collected from people by means of asking questions while they

are waiting at the train station for trains. The survey was kept as short and simple

as possible, to decrease the time that it takes for the survey to be filled out and

to make it easier for the commuters to follow. The aim was to make the survey

short enough so that there would be enough time for it to be filled in before

people having to board the train. It was estimated that each survey would take

about 5 minutes of the commuter’s time. However, there is concern that with

high frequency train services in the morning, it could be very hard for commuters

to complete the survey before the train arrives. In that respect, the survey will

mainly be taken during non-peak hours between 10a.m. and 4p.m, even

though some trial will be carried out during peak hours. It is expected that the

participants would be those who travel during non-peak hours and not travellers

in general.

The sampling method that were used were non-random and a simple-random

sample. The non-random sampling method was use when choosing the train

stations. The train stations that were chosen are listed below. The simple method

was used whereby every commuter at the train station had the same chance of

being chosen.

The survey was of quantitative type, where possible, the questions were pre-

coded. The aim of pre-coding was to avoid having to categorise the data after

the surveys had been collected, especially for the walkability index. Open

ended questions were asked in the end of the survey to allow for participants to

express other perspectives if necessary.

The train stations which were going to be surveyed have to be situated in a

suburb that meets the definition of TOD as closely as possible. Parramatta was

identified as a TOD in the western part of Sydney, Burwood in the inner west and

Bondi Junction in the eastern part of Sydney City. These places conform to the

characteristics of a TOD including:

• Higher density around the transport node

• Mixed use intended for diversity; and

• Good pedestrian connectivity.

Parramatta Station and surroundings

The sample size collected was 30 per station with a total of 90 responses. It was

decided that a face-to-face interview type survey would be the best. This

interview was conducted by going to train stations and asking commuters

questions whilst they stood at the platform of the train station. It was felt that by

having the researchers ask the questions the questions could be further

explained if the respondent did not understand or gave an inappropriate

answer. It was important to understand the journey to the train station, what

they think about the physical environment to the train stations.

Putting aside personal details, the survey consisted of 22 questions. These

questions all relate to the hypotheses. The first set of questions asked was about

the density of the journey to get to the train station. The second set seeks

understanding of the land use pattern of his/her journey and whether he/she

uses it at all. Design characteristics were asked in the final part of the survey to

gain insights on how important design was of which he/she experienced and

perceived on the journey. The respondent was allowed to answer freely why

they had chosen to walk to the train station. The data from the survey was

entered into a statistical program called SPSS. The data was then analysed.

Chapter Four - Results

A total of 90 people were surveyed, with 35 walked less than or equal to 5

minutes, 24 walked 6 to 10 minutes, 20 walked 11 to 15 minutes and 11 walked

16 to 30 minutes. There is a gradual decrease of the number of people walking

as the time to cover a distance increases. The average walking time is recorded

in the table below. Average walking time ranges from 6.4 to 11.6 minutes.

4.1 Distance VS Density

4.1.1 Density of the respondent’s residence

The above cluster bar graph shows that those who live in apartments/flats,

indicated as light brown, have the highest portion of people walking than other

housing types in any of the walking distance category. This happens across all

walking distances, except for walking distances greater than 30 minutes which

recorded zero participants. This graph shows that even with walking distances

beyond 10 minutes, those who lives in high density were still more likely to walk to

the train station. This is interesting as the number living in low density housing

would be expected to increase as distance from a transport node increases.

The survey shows a different reality. Low density residents are expected to be

less likely to walk for all walking distances than high density residents.

(Note: Single detached, semi-detached and town houses have been recoded into one variable for the

purpose of a more robust Chi-Square test)

A Chi Square test confirmed that the relationship between the two variables

examined is significant. This variable shows positive relational results with walking

distance.

4.1.2 Density along respondent’s walking trip

71  Page 33 

 

   

Page 34: Chapter One – Introduction · 2013-04-11 · Chapter One – Introduction . 1.1 Summary of the topic . Increasingly, the topic of health has become more and more eminent in our

The above graph examines the presence of high density housing with walking

distances. The inconsistent pattern of opinion regarding this variable suggests

that the presence of high density, that is, apartments or flats, is not a significant

factor in influencing people to walk. A large proportion of those who are in the

walking categories - ‘Less than or equal to 5min’, ‘6-10min’ and ’11-15min’

experienced very little high density during their walking trips. For those who

walked ’16-30min’ to the train station, a larger portion fell into the experience of

‘All or Most’ high density on the trip. However, this stand alone difference is

inconsistent with other walking distance categories and it alone is not strong

enough evidence to form a connection between the presence of high density

during the trip and walking distances.

The cross tabulation table above shows the exact number of people who chose

to walk from different distances and if they experienced high density during the

walking trip. The result from the table coincides with the cluster bar graph

previously shown. More people walked with an experience of ‘A few’ or ‘none’

high density during their walking trips than those who experienced more high

density. This is evident across all walking distance category except those who

walked ’16 – 30 min’. This may be explained by the fact that there were fewer

Page 35: Chapter One – Introduction · 2013-04-11 · Chapter One – Introduction . 1.1 Summary of the topic . Increasingly, the topic of health has become more and more eminent in our

samples in this category. Both the bar graph and the cross tabulation table

show no potency for the connection between high density on the trip and

people choosing to walk from various distances.

This is not to say that the presence of low density is then a more significant factor

in influencing people choosing to walk to get to the train station. As ‘All or Most’

and ‘A Few or None’ are tied statistically in most walking distance categories

except in the instance of ‘less than or equal to 5 min’, which by far, ‘A Few or

None’ was the most dominant answer. This could be due to proximity to the train

station and transit oriented layout of the area, which means that land use

density would have been intensified. This is confirmed by the next figure

showing insignificant percentage differences between the variables ‘All or Most’

and ‘A Few or None’ in the test of presence of low density and walking

distances.

The relationship between presence of low density on the walking trip and

walking distances is characterised by a relatively close gap in percentages

between the categories. Presence of low density on the trip is shown to have no

significant influence on people choosing to walk. This finding shows density

along a walking trip does not link to people’s choice of walking.

4.2 Distance VS Diversity

4.2.1 Businesses around respondent’s resident

In the above graph, presence of businesses around residences has been tested

against different walking distances. For those who walk 10 minutes or less, more

people walk who live near businesses than those who didn’t. However, those

who don’t live near businesses still took up a substantial portion of about a third

of the total persons who chose to walk for distances up to 10 minutes. This is

unusual as businesses are prevalent within a 10 minute walk from the transport

node in a transit oriented suburb, yet those who lived near businesses did not

form the dominant pattern within these distances. This reality weakens the

relevancy for this variable. The relationship between presence of business

around residence and walking becomes even more irrelevant when the walking

distance gets beyond 10 minutes as a substantial portion of respondents do not

live near businesses. This is especially the case for those who live ’11-15 min’ from

the train station.

The strength of the diversity factor was further examined with the variable

occurs at all walking distances except for the ’16-30 min’ category. To verify the

significance of this variable, a Chi Square test was used.

(‘All or Most and ‘Some’ have been recoded into one variable for more robust Chi Square test)

The test was inappropriate in this context as more than 15% of cells had

expected counts of less than 5. For now, it can only be said that presence of

businesses along a walking trip has some potency for those who chose to walk

from various distances but this is not statistically proven. For that reason, we may

look to the next variable, usage of business, for conclusive comment on the

relevancy of business with walking at different distances.

4.2.3 Business usage by respondent

Page 40: Chapter One – Introduction · 2013-04-11 · Chapter One – Introduction . 1.1 Summary of the topic . Increasingly, the topic of health has become more and more eminent in our

The insignificant influence of the business level on the walking trip may be

explained by the above graph indicating the proportion of people who actually

use the businesses along their walking trips. No dominating pattern is found with

lack of a constant tendency on either of the answers. More people answered

‘no’ for walking distances less than or equal to 5 minute and 11 to 15 minutes.

However, more people answered ‘yes’ for walking distances of 6 to 10 minutes

and 16 to 30 minutes respectively. Drawing from the results then, we conclude

that business is not a statistically significant factor and hence, the hypothesized

relationship between the previous variables about businesses near the residence

and on the trip is unlikely to have a significant influence on how long people

choose to walk. However, it should be noted that the relationship may differ if

the respondent was asked if he/she had used a business in the previous week

during their walk to the train station instead of for the duration of one walking

trip. This will increase the accuracy of whether the walkers were interested in the

businesses at all. This is however another hypothesis which requires further

investigation.

4.3 Distance VS Design

4.3.1 Directness of the walking trip

Directness of the walking trip is very likely to have association with people

walking as a large portion of walkers selected ‘strongly agree’ in answering

whether their walking route was direct. Walkers appeared to have chosen their

walking route as directly to the train station as possible. The ’11 – 15 min’ walking

distance category ranked highest in disagreement (either somewhat or strongly

disagree) with their walking route being direct. This may be due to the fact that

the farther a site is located from a train station, the more corners may have to

be passed in order to get to the train station. This fact is very much true even for

transit oriented suburbs. However, interestingly, those who walked 16 to 30

minutes, have a lesser proportion of people who disagree with their walking

route was direct, in spite of being at locations farther than 15 minutes. This may

Page 42: Chapter One – Introduction · 2013-04-11 · Chapter One – Introduction . 1.1 Summary of the topic . Increasingly, the topic of health has become more and more eminent in our

be due to fewer samples in this category. Overall, those who chose to walk to

get to the train station were the ones who found themselves walking on a direct

route. A Chi Square test suggests that such relationship is significant.

(‘Strongly Agree’ and ‘Somewhat Agree’ have been recoded into one variable. ‘Somewhat Disagree’ and

‘Strongly Disagree’ have been recoded into another for this Chi Square test)

However, as there were, in this instance, more than 15% of cells that had an

expected count of less than 5, this finding is not a reliable one. A larger sample

size is required for a more appropriate Chi square test.

4.3.2 Availability of alternative walking route

Page 43: Chapter One – Introduction · 2013-04-11 · Chapter One – Introduction . 1.1 Summary of the topic . Increasingly, the topic of health has become more and more eminent in our

The table above shows a dominant pattern of walkers agreeing that they could

choose an alternative walking route to get to the train station. This is the case for

those who walked 6 to 10 minutes and 16 to 30 minutes. Only those who walked

5 or less minutes showed a different pattern. This different pattern may be

explained by the fact that the walking trip for those who live very close to the

train station could very well be as direct as one straight route and hence their

trend of fewer alternative routes. This variable was examined by the Chi Square

tests.

The Chi square test above suggests that the availability of an alternative route

has some relationship with the walking distance variable. It is noted that the

provision of an alternative route is dependent on street pattern and connectivity

from various studies. These results lead us to conclude that the street pattern

and level of street connectivity to the train station have some relationship with

people who chose to walk to the train station from different walking distances.

This is especially the case for people living beyond 5 minutes from the train

station.

(‘Strongly Agree’ and ‘Somewhat Agree’ have been recoded into one variable. ‘Somewhat Disagree’ and

Provision of well maintained sidewalk is tested against different walking

distances. The tables above show there is no significant tendency of well

maintained sidewalk lead to the decision to walk from all walking distances.

However, a Chi Square test is inappropriate is this instance as more than 15% of

cells had expected count of less than 5. This leaves us with a suggestion that the

two variables may have some linear pattern of expectancy but the strength of

the relationship cannot be proven in our test.

(‘Strongly Agree’ and ‘Somewhat Agree’ have been recoded into one variable. ‘Somewhat Disagree’ and

This time the variable of “availability of trees” during the walking trip is tested.

Like the previous variable, some tendency is found between high availability of

trees and the more people walking from different distances. However, a Chi

Square test refutes such theory. This finding shows the availability of trees is not

relevant to walking to a train station.

The above results of the two variables on the perceived natural and built

environment show two trends. One is that the closer a person walks to the train

station, the more likely he/she dislikes the natural and built environment. The

other trend is there seemed to be a slight shift of opinion, from disagreeing to

agreeing, of the natural and the built environment for those who had to

walk’16 – 30min’. There may be various reasons for that including lesser tall

buildings and an increase of natural features as distance from the train station

gets longer. Overall, there are no signs that the natural and built environment

variables have any relationship with the walking distance variable as

inconsistent opinions were indicated at different walking distances. Hence, the

perceived attractiveness of the environment, both natural and built, is highly

unlikely to have any relevance to people choosing to walk from different

distances.

Some linear trend can be spotted with safety from traffic on the walk trip and

people who chose to walk from different distances. The answer of ‘Strongly

Agree’ with feeling safe from the traffic dominated all categories of walking

distance. The answer of ‘Strongly Disagree’ was either ranked last or nonexistent

for this test. From the sample collected, however, it was not possible to formulate

an appropriate Chi Square test as it is recorded that more than 15% of cells has

expected count of less than 5.

‘Strongly Agree’ with feeling safe from the crime dominated all categories of

nonexistent for this test. However, the strength of the relationship cannot be

estimated in this instance as a Chi Square test recorded that more than 15% of

cells has expected count of less than 5. The later test of the sense of safety

overall of the trip may help support safety from crime is a significant factor.

4.4.3 Overall safety on the trip

Personal safety is an essential criterion when people make their daily life

decisions. This includes choosing the mode to travel. If a person found

something that will be unsafe to him/her, then that person will probably pursue

an alternative method to achieve his/her goal or simply not pursue it at all. In this

test of overall safety, only a ‘yes’ or a ‘no’ can be answered. This is to affirm

respondents’ real opinion of their sense of safety on the walk trip. The table

above indicates a linear relationship between overall safety of the trip and

different walking distances. Those who walked less than or equal to 5 minutes

recorded the highest proportion of people feeling safe overall in their walking

trips. The trend continues in other walking distance categories, however, to a

lesser extent. It is recorded that the proportion of people who felt safe overall

dropped once the distance crosses the 5 minute mark, yet those who felt safe

were still the prevalent ones in other walking distance categories. The

relationship between the overall safety of the walk trip variable and the walking

distance variable is also supported by the Chi Square test, indicating such

pattern could only have occurred 22/1000 by chance. This result enhances the

validity of the previous two variables regarding safety from traffic and crime,

which cannot be statistically proven, as it is reasonable to suggest that they form

part of the intrinsic value of overall safety.

4.5 Distance VS Other Socioeconomic Factors

A selection of socioeconomic factors is presented above for some general view

of who actually took part in the survey. Of the three train stations surveyed,

Parramatta was the only station which had a lower proportion of people who

walked less than 5 minutes than the other walking distance categories. Burwood

and Bondi Junction recorded the highest number of people who walked less

than 5 minutes, with Burwood ranked top. Parramatta was found to have the

highest number of people who walk 16 to 30 minutes. The figure is actually

higher than those who walked less than 5 minutes and tied with the number of

people who walked 11 to 15 minutes. This is less than comparable to the inner

suburb of Burwood with very few people willing to walk more than 15 minutes as

indicated.

The survey found there are more males than females who undertook longer

walking trips. This is more the case as the walking trip gets longer. Females were

more likely to walk short distances in this instance.

Those who chose to take part in this survey were in the age group 18 to 29 year

olds. This age group outnumbers all other age group in every other walking

distance category. On all occasions, this age group doubled or even tripled the

other age groups. This survey indicates that more 18 to 29 year old persons

walked to the train station than for other age groups.

The graph shows a significantly low proportion of people who were born in

Australia walked to the train station. This is the case across all walking distances.

The proportion of people who were born overseas dominates all specified

walking distances. A steeper drop of Australians who chose to walk occurred

when the walking distance had gone beyond 10 minutes. For those who were

born overseas, a drop was recorded once the walking distance gets beyond 5

minutes, however, the proportion of people remained constant for the walking

distances of 6 to 10 minutes and 11 to 15 minutes. Generally, the number of

respondents dropped further as the walking distance stretched farther.

From this graph, it is easy to see that a lot more people who didn’t own a dog

chose to walk from all walking distances. The number of walkers who owned a

dog was very low from all walking distances and the distribution was fairly even.

This indicates that dog ownership does not have any impact on whether a

person would choose to walk longer or shorter to the station.

This graph shows that people who did not own a car were the ones who were

more likely to walk. This is the case across all walking distances. Car ownership

was lowest for walking distances less than or equal to 5 minutes and 16 to 30

minutes. However, the reasons would have been very different. Those who live

less than or equal to 5 minutes may not have needed a car as the train station is

nearby. But reasons for the lack of car ownership in the 16 to 30 minutes

category could be the fact that these people had no any other option but to

walk. This is, however, only speculative as car ownership dropped steeply down

to zero as the walking distance went beyond 15 minutes. This is opposed to the

4.6 Primary Reasons

At the end of the survey, the respondents were allowed to answer freely the

primary reasons for choosing to walk on the day. It should be noted that their

reasons have been categorized as the seven reasons in the graph above.

“Quick and Short Distance of the Trip” counted 58

Both “Cost related” and “Health related” reasons counted 20

“No Choice” counted 10

The walk being “enjoyable and comfortable” counted 7

Both “En-route to other uses” and try to “Save the Environment” counted 1

4.7 Results vs Literatures

According to the surveys, the average distance people chose to walk was 6.4

to 11.6 minutes. This result is very consistent with the findings of the authors from

the literatures, including Cevero and the Department of Planning in New South

Wales, which suggested that a 10 minute walking distance forms the catchment

which most people will tend to walk to a transit station. This study confirms the 10

minutes ped-shed theory is happening in Sydney’s TODs and is acceptable to

most travellers.

Environmental variables were used to test against walking distances to show if

the built and the natural environment are significant factors in influencing

people to walk to the transit station. Density type of the respondent’s residence,

street layout and overall safety of the trip were found to be significant. However,

there are doubts as to the significance of these variables in environmental

perspective.

Street layout is the only variable which is significant from an environmental

perspective. This is because the design of street layout creates an environment

that can make a walk more direct and having to walk less. As indicated in the

results, a majority of people from any walking distance categories chose to walk

to the train station as directly and quickly as viably possible. This is also consistent

with the answer that most people walked because the walk was short and quick

in the last open ended question about the primary reasons why chose to walk

on the day. This is the only design aspect which supports the literature about

promoting walking through designing inter-connected streets. This is suggested

by many such as Ewing (1996).

Type of housing that the respondent lives in and overall safety of the walking trip

show some relationship with the walking distance categories, however, there

are many doubts that the relation really is an environmental one that brought

the connection. The theory of density impacts on walk distance relies on the

fact that higher density will induce more people on the street and hence

people feel more secure and invited to walk. However, the result that only at the

respondent’s residence shows significant density relationship with walking

distance and not during the trip meant that density of the trip show density is not

a significant factor when people choosing to walk. Such result discord the

theory that higher density results in more people willing to walk, which many

such as Ewing (1996) and the Department of Planning (2004) endorsed.

The 3Ds (Density, Diversity and Design) concept, encouraged by many authors

and organisations, was not imperative for people who chose to walk according

to our findings. The causes and implications of the results are discussed in

detailed in the next chapter.

Chapter Five – Discussions

‘Type of housing’ that the respondent live in, ‘Directness of the trip’, ‘Availability

of alternative routes’ and ‘Overall safety’ show tempting results that the

environment is significant for people choosing to walk. It is noted that the test of

distance versus diversity has already ruled out that high level of mix use at any

stage of the trip does not form a significant relationship with walking distances.

‘Type of housing’ indicates the kind of density of housing that the respondent

live in. This variable belongs to the test of distance versus density. However, if the

theory that high density invites people to walk is true, then it must also be true

that there must be some, if not all, high density along the trip for those who

chose to walk. As such, the theory can only be confirmed correct if there are

some, if not all, high density along the walk trip that the people, who responded

to the survey, took to the train station. The result shows that high density was only

significant at one stage of the walk trip and that was at the respondent’s

residence. Clearly, the environmental aspect of this variable would not have

induced the relationship as explained. The variable, however, became much

more relevant if interpreted as a socioeconomic factor. The socioeconomic

data gathered shows us that those who chose to walk were mostly in their 18 to

29 years of age, born overseas, single and who don’t have a car. These suggest

that the respondents were probably modest in their socioeconomic status. This

information is more likely linked to the respondent’s choice of housing of high

density than the possibility of wanting to live in a high density housing and have

people live closely around. If such scenario is valid then the correlation of ‘type

of housing’ and walking distances become much more sensible as it explains

why density along a walking trip did not matter. Our study shows that more

Page 62: Chapter One – Introduction · 2013-04-11 · Chapter One – Introduction . 1.1 Summary of the topic . Increasingly, the topic of health has become more and more eminent in our

relevance can be drawn from a socioeconomic perspective more so than

environmental.

Both ‘Directness of the trip’ and ‘Availability of alternative routes’ are indications

of the kinds of street layout that people chose to walk in. This is the only relevant

environmental factor which showed a likely relationship with the walking

distance variable and can be explored further.

However, no other design features in both the built and the natural environment

were found to be significant. This weakens the association of design and walking

which was suggested by many such as Lee and Vernex (2006) and including

government agencies and organisation such as the Heart Foundation of

Australia.

It is not difficult to understand that safety on the trip was a basic requirement

when people choosing a transport mode. The results have shown the same

pattern that safety is a significant factor. This coincides with authors who

suggested that and more effort can be put in to create safer environment for

walking including more awareness for Crime Prevention Through Environmental

Design (CPTED).

5.1 So what really matters to them and to planners?

If the built environment does not matter, then what does? Drawing from the

graph showing the answers for the question of why people chose to walk to get

to the train station on the day, lesson can be learned from what really matters

for walkers. It is noted that the highest rated answer was ‘quick and short

distance of the trip’. This is a time factor in which can be remedial through urban

design of the place such as more focus on enhancing street connectivity and

placing housing and employment within direct route of the train station so

residents and employees can quickly get to the train station and other

destinations with shorter distance.

Cost related answers were second most rated factor, together with the health

related factor. Cost is partially linked to the socioeconomic status of a person.

Walking has a good advantage in this category as it virtually cost nothing and it

will be a transport mode that is popular with people who wants to spend less.

Indeed, most of those who participated in the survey were the ones who

seemed to be less affluent. Most of them live in higher density housing such as

flats and apartments and do not own a car. In an urban planning perspective,

more affordable housing should be built around the 10 minute walking

catchment of a transit station as these people are more likely to walk and use

the public transport.

Walking, even it costs nothing, still appears to be less attractive to the majority of

the population as, at present, the cost of automobile is still acceptable and

comparable to public transport. As such, walking as an intermodal mode would

Page 64: Chapter One – Introduction · 2013-04-11 · Chapter One – Introduction . 1.1 Summary of the topic . Increasingly, the topic of health has become more and more eminent in our

only raise attractiveness if the cost of the subsequent mode is justified. Rail

transport as the subsequent mode is not the case at the moment. To rectify this

particular issue, it is recommended that some monetary reward program may

be initiated by railway operator to benefit those who ride regularly. Discount

may be offered to those which can verify living more than 800m (10 minute walk)

form the train station. This in turn will bring more people walking as cost is an

important integral factor when people decide on a transport mode.

Health related answers had the same level of counts as costs related answers.

Interestingly, not many over 30 year old participated for this survey. This is good

news for our younger generations but a bad news for those who are over 30

years old. More publicity can be made in relation to the benefits of walking,

especially longer walks, to those who are over 30s. The promotion could be a

message that in fact walking is healthy while costing nothing. At the moment,

there is no environmental instrument which planners can foster the message of

health. The Heart Foundation of Australia, instead of preparing more planning

guidelines, could be spending more time and effort in promoting the health

benefits of walking so people understand what as little as walking can do to

their health.

A decision matrix was prepared below to try to gain a clearer picture of how

attractive walking weight according to the three answers which were reported

to be important. It should be noted that the points and weighting given to each

situation are only estimations. The decision to give a high point for automobile

travelling time (Quick time-wise) was influenced by results of a transport

experiment conducted by Sydney Morning Herald on 1 August 2008 titled “The

great commuter race: car vs bike, scooter, foot and public transport”, in which

automobile was relatively quick even during peak hours compared to public

transport on a regular day. The higher the total point, the more attractive that

mode is to a commuter.

It is noted that under all circumstances but one, automobile is the more

probable decision. That particular exception occurs when a person considers

time is not an important factor in his or her journey. In that instance, it

accounted a point of 6.6. Walking and getting onto public transport only

became attractive in this particular circumstance, accounting a similar point of

6.5.

In saying that, such exception situations virtually do not exist in our daily lives. This

means people will always be driving their automobiles, until one day, driving is

not faster to get to a destination anymore. If the travel time for automobile

becomes slower combined with increased automobile running cost and

awareness of healthy lives, it will surely produce outcome according to the

findings. Until then, we can only hope neither our lives nor our planet die before

such realisation.

Chapter Six - Conclusion

There were a number of issues which limited the type of sample this research

gathered. Time was an issue as it was virtually impossible to conduct a survey

during peak hours. No sample was gathered at peak hours as travellers were

rushing to get on one of the high frequency trains that depart every couple of

minutes from the train stations elected. The sample therefore had to be

collected during non-peak hours when travellers had the waiting time. Attitude

was another issue. Some over 30s were asked to participate in the survey,

however, a large number of them refused. These age groups were seemed to

be very sceptical in taking part in a survey. It is now understood, after some

failures in taking samples in this research, that surveying people, by itself, is a skills

that have to be learnt. There is a need to formulate strategy aimed specifically

at different age group for taking samples.

However, this research does tell us something about the topic of walking

distance and its’ connection with the environment. The result shows that

environmental variables do not matter very much overall. It is not a single

important factor when people choosing to walk. The causes of some variables

which strike significant statistics to the walking distance variable were rather due

to their non-environmental attributes. The decision matrix shows theoretically

people are more concerned about accomplishing getting to the final

destination as soon as possible rather than anything else. The three most

important factors of getting there quickly, being healthy and at minimum costs

suggest that people seemed to be more concerned about themselves rather

than environmental. As such, the final remark for this thesis is that only plans or

solutions that can translate environmental concerns into the ‘I’ or the ego

concerns will help walking to revive once again in our towns and cities. Until

then, the favourite still is cars, cars and cars!
