摘要: 交通流诱导系统的应用,使得传统的路网系统随机用户平衡发生了变化。本文把交通流诱导系统的效益费用和交通流诱导条件下的随机用户平衡结合起来,以交通流诱导效果和建设费用问题之间的相互关系为基础,寻找交通流诱导系统建设和随机网络平衡的综合优化方案。文章采用双层规划模型描述了系统最优和交通流诱导条件下的随机用户平衡之间的相互作用,并给出了灵敏度分析算法。

Abstract: With the application of the traffic flow guidance system (TFGS), some travelers will choose their paths according to both the guidance information and their experiences. In this paper, the benefit-cost of the traffic flow guidance system and the random user equilibrium under the action of traffic flow guidance system have been combined. Based on the relationship between the effects of traffic guidance and the construction cost, the optimization plan is founded. The relationship between the optimization system and the random users under the action of traffic flow guidance system is described by using the bilevel programming system, and an arithmetic based on the sensitivity analysis is put forward.

Key words: bilevel programming, traffic flow guidance, stochastic user equilibrium, pospect theory
