城市交通拥堵和轨道交通

Urban traffic jams and rail transit

我国城市交通拥堵之严重，已成为建设我国和谐城市目标的最强不和谐音符之一。城市交通拥堵说到底是城市交通需求和交通供给矛盾的产物。面对城市汽车保有量急剧提高的汹涌来势，又好又快地发展城市公共交通，特别是大力建设以地铁为主的高速大流量轨道交通已成为普遍的共识。“十一五”以后，我国的特大城市，如北京、上海、广州等的轨道交通网将基本形成，公共交通的比例将明显提高，

In China urban traffic jams are serious and have become one of unharmonious factors in completing the target of building harmonious cities. Urban traffic jams are the offspring which is caused by the contradiction between urban traffic demand and supply. Facing the strong trend of urban auto increase, rapid and good development of urban public transit, especially building high-speed and great-flow rail transit in which metro is main, has come to the common agreement. After ＂eleventh five years plan＂, in mega cities, such as Beijing, Shanghai and Guangzhou, the rail transit nets will basically be formed, the proportion of rail transit will be higher.
