道路拥挤定价下的公交收费模型研究

为了在执行道路拥挤定价政策的前提下制定公共交通的收费标准，提出可行的定价模型，根据交通行为科学的有关理论和方法，采用了两层规划技术建立了道路拥挤定价下的公交收费模型，上层规划为交通系统优化，下层规划为拥挤定价下的路网随机平衡问题。以广州市为研究对象，计算了拥挤定价下广州市公交线网的最优价格体系。研究结果表明：所提出的模型能够描述出行者和交通管理部门分别在出行和交通管理中的决策行为，较好地解释了用户平衡、路段路径流量和阻抗、交通需求、拥挤费、公交票价、出行成本等相互之间的逻辑关系。

Study of bus toll model under urban road congestion pricing

Studying of bus toll methods under road congestion pricing,authors put forward a feasible pricing model as decision-making reference for transportation policy makers.According to theory and methods of traffic behaviors science,authors employed bi-level programming technology to establish bus toll model under road congestion pricing.The up-level of the model optimized traffic system and the low-level of the model interpreted the problem about stochastic user equilibrium of road network under congestion pricing.Regarding the city of Guangzhou as a typical case,optimal bus toll system for bus road network was calculated aimed to the cases:congestion pricing policy should be executed.This study shows that the model can state decision behavior in traffic management department and travelers and can correctly interpret the mutual logic relation in user balance,route flow,traffic demand,congestion fee,bus toll and trip cost.
