基于2D公路网模型的EpS车队发现方法

EpS convoy discovery approach based on 2D road networks

对公路网中车辆信息进行监控以发现密集行驶的车队,将会对交通调度起到重要的辅助作用。提出了一种新的公路网中车队的定义,采用2D模型对公路网进行建模,在此基础上以2D模型中的路片为基本单元,提出了EpS(endpoint scanning)车队发现方法。最后通过实验证明了该方法在性能上的优势,并说明了其在车辆调度、缓解交通压力中的作用。

Monitoring traffic information and discovering convoys on the road network plays an important role on assisting the traffic control.This paper proposed a new concept of convoy on road network,and adopted 2D model to modeling the road network.Based on these,it regarded road segment as the basic unit,and proposed EpS（endpoint scanning） convoy discovery approach.Finally,the experiment proves the advantage in performance of the approach and explains the effect of vehicle scheduling and reducing traffic.
