从城市交通外部成本分析公交优先的必要性

在论述城市交通外部成本构成和量化情况的基础上,对城市公共交通和小汽车的外部成本进行了比较,指出造成我国城市客运交通结构性失衡的根本原因是由于交通外部成本没有内部化。实现交通外部成本的内部化将提高公共交通在出行中所占的比例,这对建立合理的客运交通结构有重要的意义。

Analysis on the Necessity of Public Transport Priority in Aspect of the Exterior Cost of City Traffic

Based on a presentation on the structure of urban traffic exterior costand its quantitative status, the paper compares the exterior costs of the publictransport with that of car transport and unveils the reason for the unbalance ofurban passenger transport structure is that the exterior costs of traffic behaviorsare not internalized. Internalizing the exterior costs of the traffic can increase theproportion of the public transport in total trips, which is of great importance for thereasonable structure of passenger transport.
