Increasing vehicle ownership and usage is becoming a great threat to the urban environment in Metropolitan areas in Southeast Asia. Economic growth and its related effects such as increasing income and mobility motivate travelers to own private vehicles. Also, insufficient supply and inferior quality of public transportation may encourage travelers to own and use private vehicles. Even though public transport facilities are getting improvements in most Asian cities with growing economy such as increasing supply and improving quality, there is a considerable gap between demand and supply of transport facilities. There is a direct relationship of vehicle ownership and ridership on public transport. In a vehicle-based society, public transport services tend to decline in quality. Therefore, investigation of travel demand is important to understand the future transportation system including expediency and role on public transport. By considering the mobility crisis in Asia, this study attempts to investigate travel demand in selected cities in Southeast Asia. By using the estimation results for travel demand, comparative study is conducted among the selected cities. Since travel data are scarce in Asian countries, the comparative investigations are very rare in the literature. Several travel demand models are developed using discrete choice modeling techniques considering Bangkok, Kuala Lumpur, Manila, and Nagoya as case studies. Estimation results of the mode choice models are successfully incorporated to compare travel demand trends in different Asian cities. The outcome of the developed models is expected to use as accessibility information for modeling vehicle ownership in the cities concerned.
