常州市客运中心周边区域交通仿真评测和交通组织设计

On Regional Traffic Simulation Evaluation & Traffic Organization Design of Changzhou Transportation Center

根据研究区域交通组织设计方案,建立VISSIM微观交通仿真模型。在现状交通调研数据的基础上,对模型中的驾驶行为参数、车辆行驶速度进行标定,并通过饱和车头时距和行程时间等指标,对标定后的模型进行校验。最终,通过微观交通仿真评测和交通组织优化、交通设计优化之间的反馈互动的方式,对研究区域内交通组织和设计方案提出优化和改善建议。

According to regional traffic organization design plan,microscopic traffic simulation model is built up in VISSIM.On the basis of current traffic surveying data collection,driver behavioral parameters and vehicle speed of the model are calibrated,and moreover,the model calibrated is verified via indexes of saturation headway and journey time,etc.Finally,through the feedback interactive method of microscopic traffic simulation evaluation,traffic organization optimization and traffic design optimization,optimization & improvement suggestions are recommended for regional traffic organization and design plan.
