An increase in environmental load from the transport sector is of particular concern in Asian mega-cities due to the anticipated increase of automobile traffic. This paper aims to propose a framework for an inter-city comparison of Asian mega-cities in order to evaluate their states of urban spatial structure, transport and environmental situation. Motorization, as the dominant factor of increases in environmental load from the transport sector, has the characteristics of irreversibility and synergism with urban sprawl. To deal with such issues, five topics are introduced: 1) induced vehicle traffic due to road improvement, 2) the relationship between vehicle-related taxation and road budget, 3) the relationship between public transport improvement and motorization, 4) the impact of urban planning and land use management, and 5) public consensus for enforcing policy measures for Environmentally Sustainable Transport (EST). Finally, the paper describes the necessity of benchmarking based on the given five topics for inter-city comparison and relative evaluation.
