The urban transport sector remains a major contributor to air pollution in Asian cities. Decision makers and development agencies are starting to realize that more active policies are required to address the problems of air pollution, road safety and congestion associated with rapid motorization.
An emerging movement in developed and developing countries is the promotion and improvement of public transportation and non-motorized transport in urban areas. In Asia, there are a number of cities with projects on improving public transportation (Bus Rapid Transit development), non-motorized transportation and pedestrian access. Experience from these cities have shown that substantial benefits on urban air quality and traffic congestion can be achieved, not to mention the relatively 'cheaper' cost required in implementing the project.
To plan effective sustainable urban transport programs and policies, it is important to have a good picture of the manner in which the urban transport sector is developing. A frequently heard complaint is that there is no recent overview of modal split data and trends therein for cities in Asia. The Clean Air Initiative for Asian Cities (CAI-Asia), with the help of other organizations like EMBARQ/WRI Center for Transportation and Environment and the Institute for Transportation and Development Policy (ITDP), has therefore taken the initative to gather updated information on modal split data in selected Asian cities.
We would like to receive your comments on the data that we have gathered. If you had additional studies please send us copies of the studies. You can also add the information to the table but in that case please send us the complete reference for our information. We are especially interested in trends for individual cities, which have been calculated making use of the same methodology and definitions for the different years. Some trends can be observed from the data posted but in many cases different definitions and methodologies have been used that make the trends somehow questionable. Kindly direct your inputs to Aurora Fe Ables , if possible, by 30 June 2005.
