摘要
结合路段实测车辆运行数据,对某高速公路典型断面车速分布规律、不同车型车速离散性、大小型车速度差极差比等特征进行分析,并就不同车型车速特征对交通安全所产生的影响进行探讨。结果表明:高速公路交通安全特性受行车车速、车速离散度及大小型车车速一致性因素影响,加强车速管理,控制车速离散程度,提高大小型车车速线性一致性,可以在一定程度上减少事故率,提升行车安全性。
According to the actual vehicle data of the selected road section,this paper analyzes the characteristics of an expressway such as the speed distribution law of typical sections,speed discreteness of different vehicle types,and the range ratio of the speed difference between large and small vehicles,and discusses the impacts of different vehicle types and speeds on the traffic safety.The results show that expressway safety characteristics are influenced by driving speed,speed dispersion,and speed consistency between large and small vehicles.So strengthening speed management,controlling speed dispersion,and increasing linear speed consistency between large and small vehicles can reduce the accident rate to an extent and improve driving safety.
