城市交通拥挤的成因探析

本文主要针对中国城市的交通状况,对交通拥挤产生的原因进行了分析.首先从交通拥挤的概念入手,对城市交通拥挤的成因进行了系统整理,将其分为四类:车辆影响、交通需求、交通设施和非机动车流,并详细进行了论述.在此基础上分析了拥挤的两种类型--周期性拥挤和非周期性拥挤--各自产生的过程以及各成因之间的相互作用.考虑了国内城市与发达国家城市所不同交通流的状况,主要是行人流和非机动车流对于交通的影响,并对此进行了分析,为有效的缓解城市交通拥挤提供一定的理论支持.

Nature of the Urban Traffic Congestion in China

This paper considers with the concept of the urban the authors grouped nine root the causes of urban traffic congestion in China traffic congestion, and through the systematic causes of the urban traffic congestion into Beginning collation, four broad categories, that is, traffic-influencing events, traffic demand, physical highway features, and non-motor vehicle flow. There are two types of traffic congestion, recurrent congestion and non-recurrent congestion. Then, the particular courses to produce these two congestions and their interaction were analyzed. The big difference between China and the developed countries in urban traffic congestion is the effect of the non-motor vehicle flow. This research will build the foundation for the effective urban congestion mitigation.
