基于灰色聚类评价的收费站分流区交通安全评价

Traffic Safety Evaluation of Toll Station Diversion Area Based on Grey Cluster Evaluation

高速公路收费站分流区交通运行特性与基本高速路段存在较大差异,车辆间的相互作用较为复杂,带来了一系列的交通安全问题。首先对收费站分流区进行交通调查,并基于VISSIM软件仿真获得交通冲突数据,最后基于灰色聚类评价法对收费站分流区进行了交通安全评价。

There are significant differences in the traffic operation characteristics between the diversion area of highway toll stations and the basic highway sections,and the interaction between vehicles is more complex,which brings a series of traffic safety issues.This article first conducts a traffic investigation on the diversion area of toll booths,and obtains traffic conflict data based on VISSIM software simulation,Finally,based on grey clustering evaluation,the traffic safety evaluation of the diversion area of toll stations is studied.
