摘要
将一个用于分析两条路径网络中信息对交通行为影响的工作推广至一般平行路径结构的交通网络中,建立了随机均衡和确定性均衡两种分配模型,分析了信息发布对平均出行成本的影响,并研究了表征行为随机程度的模型参数与系统性能指标之间的关系.
This paper further investigates the impacts caused by travel information systems on traffic behavior through extending the authors' previous work to a general urban transportation network with parallel routes. The stochastic and deterministic userequilibrium assignment models are used to carry out the analyses, i.e., computing the changes of average travel costs before and after the introduction of the information system. We also study how the parameter of the logit_based stochastic model affect the average individual travel cost, and how the information system induce potential traffic demand.
