摘要
基于微观交通仿真模型CORSIM中交通仿真与交通分配相结合的特点,在仿真模型中将路网的OD流量通过按动态规律沿时间轴加以扩展,使之成为一个时变OD矩阵,再分析研究路段自由流车速与高峰时段路网流量的动态关系,从而进行动态交通分配的建模研究尝试.
Based on the feature of the combination of traffic simulation and assignment in micro-simulation model-CORSIM, the paper extends the network OD flow to a time OD matrix along the time-axis in light of dynamic rule in the model, and it analyzes the dynamic relationship between free-flow speed and network traffic volume in order to attempt to model dynamic traffic assignment.
