The invention discloses a rapid traffic demand estimation method for urban traffic simulation, and the method comprises the steps: dividing an urban region corresponding to a road network into a plurality of traffic analysis zones (TAZs) in a customized manner through road network data downloaded from OpenStreetMap based on the population density data of a target region, combining an OD matrix and the divided TAZs, and carrying out the calculation of the traffic demand of the target region. According to the distance between TAZs, the population number and the access degree data, a Gravity model is used for estimating the number of starting vehicles and the number of ending vehicles between the TAZs, a corresponding traffic demand file is rapidly generated, and then simulation is conducted on a road network through a simulation of Urbin MObilitude (SUMO). According to the method, on the basis of ensuring that the traffic demand is related to the actual situation, the time consumption and the error rate caused by manual custom are greatly reduced, and the accuracy and the reliability of urban traffic simulation by using the SUMO are further improved.

    本发明公开了一种面向城市交通模拟的交通需求快速估算方法,该方法基于目标区域的人口密度数据,通过从OpenStreetMap中下载的道路网络数据,将道路网络对应的城市区域自定义划分为若干个交通分析区(Traffic Analysis Zone,TAZ),结合OD矩阵和划分好的TAZ,根据TAZ间的距离、人口数量以及出入度数据使用重力模型(Gravity model)估算各TAZ间的出发和终到车辆数,快速生成对应的交通需求文件,进而利用Simulation of Urban MObility(SUMO)对道路网络进行仿真。本发明可在保证交通需求与实际情况相关的基础上,大幅降低因人工自定义所产生的时间消耗和错误率,进而提高使用SUMO进行城市交通模拟的准确性和可靠性。
