交通拥挤负外部成本量化模型及应用研究

交通拥挤负外部成本游离于经济杠杆调控政策的价格体系之外,未能在市场价格中体现是导致交通资源配置失衡的关键.为科学量化交通拥挤负外部成本,支撑经济杠杆需求调控政策实现外部成本内部化,从交通拥挤造成的时间延误、交通事故、环境污染这3个维度解析交通拥挤负面经济成本,构建小汽车交通拥挤负外部成本量化数学模型.以深圳市为例,计算...

Calculation Model and Application of Negative External Cost of Traffic Congestion

It appears that the negative external cost of traffic congestion has not been considered in the price system of economic leverage control policies, which causes an imbalance in the allocation of traffic resources. To scientifically quantify the negative external cost of traffic congestion, this study analyzes the negative economic cost of traffic congestion in terms of time delay, traffic accidents, and environmental pollution, and proposes a car quantitative mathematical model to reflect the negative external cost of traffic congestion. Taking Shenzhen city as an example, the paper calculates the typical negative external cost of traffic congestion in a city. The result shows that the average negative external cost of traffic congestion generated by each car in Shenzhen throughout the year is as high as 24460 CNY, and the negative external cost of traffic congestion is about 2.1 CNY per kilometer of each car. In accordance with the "user pays" principle, the economic leverage control policy charging rate should cover the negative external cost of car traffic congestion, and it is recommended to refer to a charge of 2.1 CNY per kilometer per car.
