摘要
实施拥挤收费最大的障碍来自人们对城市道路资源配置公平性的质疑,论文定量分析了拥挤收费对城市道路资源配置公平性的具体影响.在剖析城市道路资源特性的基础上,分析了城市道路资源配置公平性的涵义,研究了城市道路资源配置公平性的度量方法:计算各出行方式的城市道路资源占用,利用洛伦兹曲线和基尼系数进行分析.该方法能有效分析拥挤收费实施前后城市道路资源配置公平性的变化,并以此说明拥挤收费对城市道路资源配置公平性的影响.论文用实际数据进行了计算和分析,得出拥挤收费能够改善城市道路资源配置公平性的结论.
The biggest obstacle to bring congestion pricing into effect is its lack of public confidence on equity impacts. This paper tries to analyze the equity effects of congestion pricing from its impacts on urban road resources allocation. It sets forth the characters of urban road resources and the meaning of equity in urban road resources allocation, and makes researches on bow to measure the equity effects. It analyses the resources occupation of urban roads in every mode, and then uses Lorenz curves and Gini coefficients to narrate the change before and after urban road congestion pricing. By this way, the difference of equity in road resources allocation brought by urban road congestion pricing is found out, and the equity impacts of urban road congestion pricing are analyzed quantitatively. Also, a sample case is introduced and the practical data are analyzed to demonstrate that urban road congestion pricing can improve the public equity of urban road resources allocation.
