问答题 The 2011 is a historic moment in Chinese urbanization process, when the urban population surpassed the rural population for the first time. During the next 20 years, it is estimated that about 350 million rural population will move to cities. Such large-scale of urbanization is both a challenge and an opportunity to the urban traffic. The Chinese government has always been advocating "people-oriented" developing concept, emphasizing that people should travel by buses instead of by private cars. It also calls for the construction of "resource saving and environment friendly" society. With this explicit goal, China can have a better-planned urbanization process, and therefore divert more investment to the development of safe, clean and economical transportation system.
