摘要
结合交通规划软件TransCAD的OD矩阵反推和仿真软件Vissim动态交通分配仿真的技术优势,提出了一种较实用的交通需求OD推算方法和城市路网动态交通分配仿真技术,建立了城市路网动态交通分配仿真流程,使仿真效果达到了从宏观到微观系统分析路网规划方案以评价路网交通性能与管理效果的目的,并运用该技术方法对重庆市南坪交通枢纽改善工程组织方案进行比选,得出了交通组织方案的优劣。
Based on the advantages of traffic planning software of OD matrix estimation of TransCAD and dynamic traffic assignment simulation of Vissim, a practical method of traffic demand OD estimation and dynamic traffic assignment simulation technology of urban road network was presented. A dynamic traffic assignment simulation process of urban road network was established. Simulation results achieved the objective that the network performance and traffic management effectiveness were evaluated by analyzing network planning program from macro-analysis to micro-analysis. The technology was used to evaluate the traffic organization programs of Chongqing Nanping Traffic Hub Improvement Project. The result was satisfactory.
