基于GIS的交叉路口动态行驶时间预测方法的研究

城市路径诱导系统的一个非常重要的作用就是能动态预测车辆在某路段上的行驶时间。在传统的时间预测方法中,往往忽视一个非常重要的时间花费——交叉路口通过时间,这个时间由通过时间和等待时间两部分来组成。通过建立模型对交叉路口通过时间进行了分析和研究,仿真结果可以看出,这个时间对于路径诱导的决策性影响是比较大的。

Study of Intersection Dynamic Drive Time Based on GIS

One of the functions of route guidance system is estimating the drive time on the rode in the traditional method, people usually a more important time that is the time across of intersection: including crossing and waiting time.A model to analysis the time of across a intersection through the imitating is build. A conclusion is draw that the time across the intersection have an effect to the decision of route guidance.
