Abstract: The effect of urban expansion on transportation in growing megacities has become a key issue in the context of global climate change as motorized mobility is a major source of domestic greenhouse gas emissions. The management of forms of urban development on the city fringe in order to encourage a sustainable transport system is usually overlooked in China, although it is increasingly attracting attention in developed countries. Examining the case of Beijing, this paper aims to reveal the policy implications of urban growth management for sustainable transportation in China''s megacities. The analysis shows that in the rapid urban expansion process there has been obvious urban sprawl on the fringe of Beijing, characterized by low density and dispersed development in its physical aspect and a low degree of local mixed land use in its functional aspect. Trip distance and car use for travel on the city fringe have increased greatly due to urban sprawl. The results of the analysis suggest that urban growth management designed to curb urban sprawl would contribute to containing the growth in vehicle miles travelled in the suburbs. In addition, since urban sprawl has been greatly fuelled by increasing local government autonomy and fiscal responsibility, the negative effects of sprawling development on transportation certainly reflect the government''s failure to manage growth in the current transformation process. To achieve sustainable urban expansion, stronger metropolitan development management measures should be enforced to control local development on the city fringe and promote sustainable transportation.
