摘要
动态路段行程时间的预测是ITS动态最短路线选择的关键技术之一。根据对实际交通状况的分析,将路段行程时间分为三个部分,即自由行驶时间、排队等待时间和通过交叉口时间。模型基于路段的基本信息及实时信息分别对这三部分时间进行预测,从而实现对整段路段行程时间的动态预测,精确度明显提高。
The estimation of dynamic road travel time is one of the key technologies for the dynamic choice of the shortest path in ITS. According to the analysis on the actual traffic status, the whole road travel time is divided into three parts; free travel time, queue waiting time and passing intersection time. The time of each part is estimated based on the basic information and the real time information of roads in this model, hence the dynamic estimation of the whole road travel time is realized. The exactitude has been improved obviously.
