2.Problem Analysis

• PT network Analysis

• Stakeholder Analysis

• Policy Analysis

• Definition of Transport Accessibility

• Spatial delimitation

• Car network Analysis


Problem Analysis

• The concept of accessibility has been defined in many different ways. The most appropriate definition depends upon the intended application.

• Our definition is an adaptation of the definitions proposed by Morris et al. (1979) and Geurs & Van Wee (2004): “Accessibility is the ease* with which groups of individuals can reach a destination from a certain place and with a certain transport mode”.

* Ease is expressed in terms of travel time/costs.

Problem Analysis

• The traffic situation on the Waalbrug and the Singels will still be problematic in the future.• The new bridge (Stadsbrug) does not provide a convenient route for travelers from the north to the city center and Nijmegen South.• The Singels have an urban-road design but a regional function (access road).

Car network analysis


Problem Analysis

Traffic characteristics• Highest intensities in peak hours (indicating home-work traffic)• Main ODs: Waalsprong and Arnhem Nijmegen City center and South• High intensities in both directions • Bottlenecks: Keizer Traianusplein and Singels. Conflicting flows: Left turn direction Germany in Traianusplein, and left turns in the Singels Also: Capacity of the Waalbrug is limited

Car network Analysis (cont’d)


Problem Analysis

Travel demand from the north to the city center:• Current public transport share 10%• Ambitious plans for the future- HOV-network of six lines include one tramline• Growth in demand of 84% => pt-share 11,5%- Waalsprong 1200% growth- Arnhem South 51% growth- Spatial developing• Potential growing areas: Waalsprong, Bemmel, Arnhem Center (based on share and total travelers)

PT network Analysis


Problem Analysis

Why are not more people using public transport to access the city center?Travellers issues choosing for public transport (research Moving 2007), applied to Nijmegen situation:

• Travel time- Egress time => whole city center reachable in max 5 min walking from a stop

- Transfer time => all regional lines going through city center/Plein 1944

- Running time => dedicated infrastructure in congested areas (e.g. Waalbrug)

- Waiting time => low frequencies in smaller residential areas, Waalsprinter off peak

(each 20 minutes)-Access time => less stops on HOV lines, access time is higher.

• Price: normal fares, Waalsprinter = free for P&R users.

• Image => Nijmegen North => 67% Satisfied (Buurtmonitor ’09) average Nijmegen 85%

Stakeholder Analysis

Power vs interest grid:


Problem Analysis

CONFLICTS OF INTEREST:• Environmental groups versus Kamer van Koophandel and Entrepeneurs of the City Center The former are against more car traffic infrastructure and strive for more car reducing measures, whereas the latter claim that more infrastructure and other car oriented measures are necessary in order to increase the accessibility of the city center. The local government is situated somewhere in between those parties. • Political partiesPvdA, SP and GroenLinks are against physical infrastructural measures in the city center while CDA and VVD are willing to consider measures of that kind when proved these contribute to increase accessibility. Almost all political parties agree that parking space availability should increase, except for Groenlinks that does not mention it.• Examples of conflicting measures include the possible affection of the city characteristics when new infrastructure is built and possible removal of nature and green in case of physical measures. Also, actors favoring bike and public transport conflict with business actors (KvK, city center entrepreneurs) who claim that bike and public transport alternatives only have marginal effect and that car accessibility should be the focus.

Stakeholder Analysis (cont’d)


Problem Analysis

• Currently several measures have been proposed and are

successful:

- Waalsprinter

- Smart Pricing

• The current measures have had positive affects but in

general the accessibility problem still remains (the positive

effects are marginal).

• Current measures are expensive and not suitable, and

depend on funding from the Ministry (e.g. Smart Pricing).

• Future measures include the Stadsbrug and the extension

of the A50, but the problem on the Waalbrug will still

remain, due to: a) the realization of a new residential area

(Waalsprong); and b) autonomous growth.

5.Alternatives

•Alternative 1

•Alternative 2

•Alternative 3

•Alternative 4

•Alternative 5


Alternatives

- Goal: Better use of capacity and to distribute traffic equal over available routes- Matrix signs on the routes to Nijmegen- Smartphone applications with traffic situation status include alternatives like Waalsprinter.

Alternative 1: Route Guidance


Alternatives

- Goal: Better use of capacity of the Waalbrug - Combines HOV and pricing strategies by allowing single occupancy vehicles to gain access to HOV lanes by paying a toll.

Alternative 2: High Occupancy Toll-Lane (HOT)


Alternatives

- Goal: give an alternative to cross the Waal without using the current alternatives- Focus is more on people who work in the city center area, also people who wants to visit the city center- Parking places to park your car and use the ferry to cross the Waal- No tariff (in peak hours)

Alternative 3: Fast Passenger Ferry system


Alternatives

- Goal: Improving flow on Keizer Traianusplein- Improving flow on Traianusplein by reducing conflicts through a redesign- Facilitate left turn on viaduct- Remove conflict by lowering lanes for straight traffic

Alternative 4: Redesign Keizer Traianusplein


Alternatives

- Goal: Improving flow on Singels- Reduce conflicts on Singels by changing traffic situation and diverting flows- Reducing conflicts on two crossings (Prins Bernhardstraat and Berg en Dalseweg)- Diverting left turning traffic to Bijleveldsingel- Reduces number of traffic light phases and waiting time

Alternative 5: Reducing conflicts on Singels
