摘 要:有数据显示,在大城市、特大城市内,近70%的道路资源被小汽车占用。面对如此交通现状,中国土木工程学会理事长谭庆琏说:“私家车已到该限制的时候。大城市、特大城市上下班的主要客流只能靠大力发展大容量快速交通体系来承担。”“The Stat.data shows that almost 70% of the road resources have being occupied by the private car in big cities in China.It will have a negative effect on both the crowded traffic system and the environment in the long run. Facing the situation,Tan Qinglian,Chair- man of China Civil Engineering Society says,it is time to restrict the private car. Solving the city traffic problem must depend on the high-capacity traffic system.The situ- ation would become worse if we do not take effective measures.
