城市交通拥挤一直是世界性的研究热点和难点问题,已有研究发现出行者一般通过直接改变出行路径和出发时间的决策来间接地对路网延误现象实施应对.本文给出了一个简单的出发时间转移模型,并将其和交通分析与仿真系统(TRANSIMS)的建模过程进行集成,进而提出了一种顺序出发时间与路径选择模型.为了进一步对该模型实施模型收敛检查并验证其可行性,本文将其应用到美国底特律市区的大使桥门户重建项目中,同时设计了模型应用场景,主要包括道路封闭事件和实行的交通拥挤缓解措施,进而评价道路施工作业区对出行者出发时间转移的影响.分析结

Urban traffic congestion has been a worldwide hot spot and difficult issue,the existing studies illustrated that individual travelers generally impose the influence on road network delays by directly changing their travel departure time and route choices. This paper presents a simple departure time shift model,and integrates it with the modeling process of TRansportation ANalysis and SIMulation System ( TRANSIMS) ,and then documents a sequential departure time and route choice model. For the purpose of further implementing the model convergence check and calibrating the feasibility of the model application,this study employs the sequential model to the Ambassador Bridge Gateway Reconstruction project in metro Detroit,U. S. ,and creates work zone scenarios that contain the road closure event and implemented operational mitigration measure,in order to investigate the impact of road work zone on departure time shift. More importantly, the analysis shows that the equilibrium model solely with route choice capability may overestimate road work zone delays, compared to the model with both departure time and route choice.
