摘　　要：为了在交通影响分析中准确预测道路网络的宏观交通流和局部路口的微观交通流特征,提出利用宏观交通规划分析软件TransCAD与微观交通仿真软件TransModeler组合分析交通影响的方法。首先在TransCAD软件中运用OD反推技术对未来年交通需求进行预测,将交通需求预测模型的输出结果作为TransModeler微观仿真软件的输入初始数据进行微观仿真分析,以便利用交通仿真技术对局部关键路口微观交通流分析。通过实例验证,该方法有助于城市交通影响评价的微观层面进行定量化分析,对实践具有一定的指导意义。In order to predict and analyze the attributes of macro traffic flow on road network and micro traffic flow at intersection accurately during the traffic impact analysis,a method of combining TransCAD software with micro simulation software—TransModeler is developed.First,the traffic demand is predicted in the future by OD matrix estimation based on TransCAD software.As a result,the output of traffic demand model can be input to micro traffic simulation software——TransModeler directly to simulate and analyze the micro traffic flow of key intersection and road.Finally,a numeric test is done to show the traffic impact analysis on the micro level of quantitative analysis,and the practice has certain directive significance.
