研究了利用Mapinfo电子地图自动提取构建微观交通仿真软件Paramics基础路网的方法。首先利用MapInfo提供的二次开发工具MapX提取出代表路网几何和拓扑的特征点信息,然后对原始的特征点集进行精简近距离点、精简同一直线上点以及精简同一弧上点的操作,最后生成Paramics的路网存储文件和基础路网。根据此方法提高了Paramics基础路网建模的效率,生成的路网与原地图一致,满足微观交通仿真要求。
This paper studies the method of automatically extracting and constructing Paramics’s basic road network using Mapinfo electronic map. First of all, using the secondary development tool MapX provided by MapInfo to extract the feature point information representing the geometry and topology of the road network, then the original feature point set is streamlined, the point on the same line is reduced, and the operation on the same arc is streamlined. Paramics finally generated road network storage files and the basic road network. According to this method, the efficiency of Paramics road network modeling is improved, and the road network generated is consistent with the original map to meet the requirements of micro traffic simulation.
