大型活动下交通需求预测仿真及实例分析

摘要

大型活动的举办势必会对城市交通产生影响，根据城市举办大型活动时的交通特点，以四阶段法为研究依据，利用TransCAD交通仿真软件建立一个面向大型活动的交通需求预测仿真平台，该仿真实现的功能：交通生成预测、交通方式划分、交通分布预测、及交通分配预测，为大型活动下的路网评价提供了一套有效的分析工具。%City traffic will be seriously affected by large events held.A Traffic demand forecast simulation system for accessing the road network under large events was developed,by using simulation software TransCAD and four-stage methodologies.The functional of the simulation were described,which included traffic generation forecast,traffic distribution forecast,transport forecast,traffic assignment prediction. Therefore,it provided a set of effective analysis tool for evaluating the road network under large-scale events.
