In this report，the green development of urban transportation is refined to the level of index. Five indexes of 38 major cities in China are calculated and ranked respectively. Then it analyzes the development trend and characteristics of different indexes，and defines the weak links of the relatively backward cities in the green development of transportation. Finally，we can obtain the reasons for the differentiation of index development in different cities and propose the improvement measures through comparing the index measurement results in multiple directions both urban individual level and regional level. It is found that the cities with higher functional index are mainly in the eastern regions with more developed economies，such as shenzhen and Shanghai. Their advantages lie in the high density of bus network，subway network density and the number of taxis. The characteristics of the economic index are similar. The eastern region is ahead of other regions，among which Beijing and Shanghai are ahead of the whole country with absolute advantages. It is characterized by high investment in fixed assets of urban rail transit，road and bridge and benefit of saving passenger travel time. Regional differences in social indexes are relatively average，with leading cities such as chongqing and tianjin showing outstanding overall performance in terms of traffic safety. In terms of ecological index，cities with better performance have better control over per capita green space area and SO₂ emission. The overall performance of the western region is bright. In the eastern region，although shenzhen，Beijing，guangzhou and other cities rank the top，there is a big gap between cities within the region. Harbin developed well in terms of governance index，and most of the leading cities were outstanding in road traffic planning system and traffic coordination mechanism.
