The definition and connotation of the sustainable urban transport

This paper discusses the process of the sustainable development and then elaborates on the current situation, definition and connotation of the development of sustainable transportation. Meanwhile, the paper finds similarities and differences by comparing the international and national definitions and connotations of the sustainable transportation. It is found that while the definitions of sustainable transportation are different in different research, there seems to be a consensus that progress must occur on at least three fronts: economic, environmental, and social sustainability. Then a new dimension of sustainable development is put forword for urban transportation and a new definition of sustainable transportation is developed. This paper provides not only a reference for indentifying suitable targets of sustainable transportation strategy under the national conditions, but also a strong theorical foundation for directing the development of urban transport.
