基于灵敏度分析的收费公路费率与流量的关系研究

摘要

In this paper, the relationship between the tool rate of roads and traffic volume assignment are analysed based on traffic equilibrium assignment of different roads between an OD pair. And the application of sensitivity analysis is illustrated with a practical example, which shows the relation between toll and traffic volume under the condition of competition of different sorting roads.%在分析一个OD对中不同道路之间的交通流量均衡分配的基础上,采用灵敏度分析方法,对其中收费公路费率因素对于交通流量分配变化的影响进行了研究.并用实际算例来说明灵敏度分析方法在并行道路交通分配中的应用,即得出不同并行道路竞争条件下,收费公路费率与其交通流量之间的相互关系.
