Transport Objectives and Their Contribution to SUSTAINABILITY: 

Transport Objectives and Their Contribution to SUSTAINABILITY ECMT Report on Sustainable Transport Policy (2000) EC DG Environment’s Guidance on Sustainable Urban Transport Plans (2005)

Which Objectives Are Most Important ?: 

Which Objectives Are Most Important ? There can be tensions between objectives Priorities differ accross the countries and cities Maintaining a balance among objectives is not easy and tradeoffs are necessary Therefore, for each city / country Set the “right” priorites Pursue policies which support the higher priority objectives ( a package of consistent policies & instruments)

A Long-Term or Immediate Focus ?: 

A Long-Term or Immediate Focus ? Give sufficient emphasis to longer term impacts (Reducing GHG, increasing equity between generations, avoiding resource depletion) Others objectives affect today’s citizens and require for immediate action Given 4-5 year life of a government, policy makers focus on current needs and overlook longer term problems

POLICY INSTRUMENTS (ECMT Reports): 

POLICY INSTRUMENTS (ECMT Reports)

How Well Do Policies Use Both Demand-Side and Supply-Side Measures ?: 

How Well Do Policies Use Both Demand-Side and Supply-Side Measures ?

LARGE ROAD PROJECTS: 

LARGE ROAD PROJECTS Projects faced opposition from professional organizations and NGOs - Urban road tunnels (156 km, $2 B) - 3rd Bosporus Bridge and beltways ($2 B) - Road tunnel under Bosporus ($1.6 B) - Flyovers (126 built)

MUNICIPALTY BUDGET FOR TRANSPORTATION: 

MUNICIPALTY BUDGET FOR TRANSPORTATION In 2001-2007 period, - $ 1.93 B spent on road projects - $ 3.45 B spent on rail projects In 2007, - GMI will spend $ 2.94 billion (53.5% of its total annual budget) on transportation projects. Up to 2012, - $ 15 B is required for transportation projects - GMI is planning to allocate $ 5.8 B. - $ 2 B is required for 156-km road tunnels.

DECISION MAKING in TRANSPORTATION: 

DECISION MAKING in TRANSPORTATION Who puts the projects ? Who evaluates ? Who decides ? Who puts money ? Transparent decision making is necessary There is a credibility gap between public and politicians

TRAVEL TIME (min): 

TRAVEL TIME (min) Hyper -congestion at low level of car ownership

EMISSIONS in TURKEY (2004): 

EMISSIONS in TURKEY (2004) Turkey’s total GHG emissions = 296.6 Mt CO2 equivalent (81.8 % is CO2) Transportation CO2 = 40,5 Mt ( 12 % of total CO2, increased by 55.8 % between 1990 and 2004) Road Transport CO2 = 34 Mt (84 % of transport sector) Source: 1st National Comunication on Climate Change, Report of Turkey, 2007.

3rd BRIDGE PROJECT: 

3rd BRIDGE PROJECT Forests and wetland area of 800 ha is estimated to be demaged.

SUCCESSES: 

SUCCESSES Rail transit improvements Sea transport improvements (Sea buses, ferries) Fare integration by electronic tickets (Akbil) Extended budgets allocated to urban transport projects Increasing interest in environmental issues through news in media

FAILURES: 

FAILURES Uncontrolled population growth and urban sprawl Lack of integration of land-use, transportation, environmental and economic development plans Barriers to implementation of plans (finacial, legal & institutional, political & cultural, technological) Hyper-Congestion at untolerable levels Lack of public awareness Lack of transparent & accountable decision-making process

Slide26: 

Integrate land-use, transportation and environmental planning Improve and integrate public transport modes Improve NMT Develop reserved routes for PT SOLUTION for SUSTAINABLE TRANSPORT

Slide27: 

SOLUTION for SUSTAINABLE TRANSPORT Reduce and rationalize the use of cars, more specifically in the city centers by TDM. (Congestion pricing, parking pricing and management, traffic calming, regulatory measures) Set targets (Reduce CO2 by 30 % by 2012)

Slide28: 

A DIFFERENT WAY OF THINKING There is an urgent need for a change in the way we think about transportation (paradigm shifts) Sustainable transportation requires fundemental changes in our transportation planning practices.
