with the objectives to
Transport Demand Management shall
• Urban areas require proper road networks
• New roads attract more traffic and reduce the viability of public transport
• Transport benefits will be offset by future congestion
• reduce traffic congestion
• reduce adverse effects on the environment or public health
• generate additional revenue to improve public transport and NMT by pricing mechanisms
• reduce the total volume of traffic
• promote shifts towards more sustainable modes of transport
The challenges in urban transport and TDM
Mosaic from a bathroom in Ostia/Rome Singapore has implemented a range of mobility management measures in the Chinatown area, including pedestrianised streets, evening road closures, widened and attrative newly-pavedwalkways, tree-planting for shade, more parking restrictions, transit improvements (including bus and MRT expansion in the area), an ERP-System, and an innovative ‘smart bike’ program providing free bicycle use.
Karl Fjellstrom
125 A.D. Today
Rome saw in 125 A.D. a serious traffic problem.
As a result a regulation has been imposed that restricted the number of ox carts, food delivery transport, and chariots in the center of Rome.
TDM emphasises on the movement of people and goods, not just on motor vehicles, and gives priority to public transit and non-motorized modes, especially under congested urban conditions.
Transport Demand Management
Unter den Linden/ Friedrichsstraße:
The street belonged to everyone:
automobiles, autobusses, carriages, pedestrians
In this era, people were enthusiastic about technology and the achievements of modernity; while at the same time they felt anxious about the rapid and radical changes in their social and economic life. In Germany, this contradictory experience was especially harsh and perceptible in the urban metropolis of Berlin.

TDM policies should never be implemented as isolated instruments, but – for being successful – have always to be embedded in a comprehensive framework of Transport Demand Management measures.
Transport Demand Management measures
The push and pull approach
Source: Müller, P., Schleicher-Jester, F., Schmidt, M.-P. & Topp, H.H. (1992): Konzepte flächenhafter Verkehrsberuhigung in 16 Städten”, Grüne Reihe des Fachgebiets Verkehrswesen der Universität Kaiserslautern No. 24.
Curitiba: the unique advantage that a city development matured over more than 25 years. This influenced heavily land-use patterns. Initial spark: a dedicated and visionary mayor (Jaime Lermer)
The so-called „push and pull strategy“ is the key for sustainable transport development, and when consequently followed may have significant influence on modal split
How much of the “push” (getting people out of their cars) and the “pull” (getting people into public transport and NMT) will be applied depends on the financial resources of a given city, but even the more on the dedication and leadership of the mayor and the city council.With very limited financial resources, for example parking management and access restrictions (push) can be implemented, while on the other hand public bus transport can be made considerably more attractive by a bus regulation and concessioning scheme and a reallocation of public space (for example into cycle lanes and/or bus lanes/BRT systems).
TDMs relevance for lower income developing cities
Travel Demand Management
• Recognizes that travel demand is not given, but is a function of transportation policies, pricing, investments, choices
• Is vital to creating high performance, cost-effective transportation systems
• Is the natural complement to transportation supply management, land use planning, and environmental/natural resource management
Conclusion:
- Supply-oriented measures often have negative side effects, will not help to ease transport problems in the long term, and will be a heavy burden on city budgets
- An alternative approach: Limit investments in new infrastructure and transport systems, and make more efficient use of what is already there… -manage road space and public space, democratise it in favour of citizens and modes with higher capacities than cars

• Focus on measures open to rapid implementation by the local government, with limited reliance on help from the national level or foreign donors
• Consider ‘least cost principle’ considering how to maximise mobility at the lowest cost, including demand management options
• Involve the public: Consultative workshops, seminars, focus groups, meetings, public awareness campaigns…

54% of all trips are by non-motorized means of transport (walking, bicycle).
private car use is smaller than 30% whereas public transport covers nearly 40% of all trips.

Major shifts in the modal split
Major shifts in the modal split proved possible (e.g. in Zurich, Freiburg, Münster) when the local authorities implemented a comprehensive and integrated urban policy.

Integration
Improving Public Transport System
§ connect easily between different public transport vehicles and between modes
§ short waiting times
§ reduced travel time
§ greater flexibility and accessibility
§ easier trip planning for passengers
§ expands freedom and range of destinations offered by public transport
Need
Benefits:
Mobility Options like:
§ Enhancing Non-Motorized Transport (like Walking and Cycling);
§ Improvement in Public Transport System;
§ Improvements to taxis, auto rickshaws, car rental, delivery services, car-share (and other car-like services that complement public transport and NMT and make it easier to live without owning a car or motorcycle)
Measures for Improving Mobility
From theory to practice: Examples of TDM measures applied
05.10.1
Promoting Public Space
Main Components of Sustainable Transport• Public Transport with
priority over all other modes on the road
• Non-motorisedtransport
• Creating/conserving public space
• PT Integration
• TDM measures
05.10.1
Do you see these factors here?
Traffic Cells: Making Walk and Bike Access Central
§ Direct paths with priority for pedestrians, bikes, public transport
§ Development focus around public transport station
§ Examples: Houten, Delft, Gronigen (Neth.); Gottenberg(Sweden); Davis, California, Bremen (Germany); Japan
Key issues:(1) Coherence:
§ Connect all important origins and destinations
§ Integration with public transport(2) Directness:
§ Direct routes and avoidance of detours
(3) Safety:
§ Segregated bicycle lanes
(4) Comfort:
§ Smooth pavement
(5) Attractiveness:§ Avoid deserted and isolated
routes

§ Multiple side-effects limit their effectiveness

Benefits of TDM approaches
§ Often achievable at low cost
§ High impact: reduction of pollution and travel times, accidents; less environmental costs
§ More compact cities, socially integrated
