Beijing suffers a great road transport problems, including environment pollute, congestion, and etc. A research supported by the national basic research program of China to solve transport related environmental problems introduced an environmentally sustainable transport research framework. Results showed that the dramatic increasing of total vehicles was the key driving force. NOx and CO2 emitted by vehicles were two main pollutes that might touch the environmental capacity in 2020. Policy instruments were proposed to control the total vehicle, the NOx emission and the CO2 emission. The time arrangement of policy instruments was partly accepted by the local government. Continuous monitoring showed that the effects of the policy planning were mixed.
