中文摘要: 由于出行者的出行路径费用感知偏差,出行者在出行路径选择中往往并非简单使用最短路径或遵循用户均衡原则,基于随机效用理论的随机路径选择模型在模拟出行者出行路径选择过程中占据重要地位。本项目针对随机路径选择模型的交通悖论(亦简称随机路径选择悖论)特征展开研究。研究内容主要包括:(1)不同随机感知误差分布对随机路径选择悖论特征的影响;(2)缓解路径重叠效应的扩展logit随机路径选择模型与传统logit随机路径选择模型的悖论特征差异性分析;(3)拥挤效应对随机路径选择悖论特征的影响;(4)多候选添加/删除路段情形下随机路径选择悖论的局部属性甄别及其网络结构特征分析。该研究将丰富对随机路径选择悖论的理解与认识,为提升道路交通基础设置建设效率,避免资源无序投入,构建更为科学合理的道路交通系统服务。

英文摘要: Because of the travelers’ perceive error of travel route cost, travelers’ route choice usually does not just simply choose shortest route or follow user equilibrium principle. The stochastic route choice models based on random utility theory are highly important for formulating travelers’ route choice process. This project studies traffic paradox features of stochastic route choice models. The main contents include: (1) the different stochastic perceive error’s effect on paradox features in stochastic route models; (2) paradox difference analysis of extended logit stochastic route choice models slacking route overlapping issue and original logit stochastic route choice model; (3) the congestion effect on stochastic route choice paradox features; (4) local attribute identification of stochastic route choice paradox features with multiple adding/deleting candidate links and its network structure features' analysis. This study will enrich the understanding and recognition of stochastic route choice paradox and serve for improving road construction efficiency, avoiding resource unordered input, and constructing the scientific and reasonable road traffic system.
