2011年是中国城市化进程中的历史性时刻，其城市人口首次超过农村人口。在未来的20年里，预计约有3.5亿农村人口将移居到城市。如此规模的城市发展对城市交通来说既是挑战，也是机遇。中国政府一直提倡“以人为本”的发展理念，强调人们以公交而不是私家车出行。它还号召建设“资源节约和环境友好型”社会。有了这个明确的目标，中国城市就可以更好地规划其发展，并把大量资金转向安全，清洁和经济型交通系统的发展上。

In the next two decades,it is estimated that about 350 million people will migrate from rural to urban areas. Such of sacale of urban development is both a challenge and an opportunity for urban transportation.

With this clear goal,China can have better-planned urbanization process,and make a large investment in the development of safe,clean the economical transportation system.
