基于SUMO软件的公路作业区行车风险仿真分析

Simulation Analysis of Driving Risk in Highway Work Zone Based on SUMO

文章基于SUMO仿真软件,参照《公路养护安全作业规程》(JTG H30—2015)关于作业区各个区域长度的设定要求,在SUMO中构建仿真环境。试验工况为:封闭右侧单车道。结合实际工况,交通量和大车比例均分为三种情况,采用TTC和DRAC作为评价指标。实验结果表明,在任意工况和任意交通量条件下,车辆进入上游过渡区所形成的“TTC风险墙”、“DRAC风险墙”位置均随着大车比例的上升而提前,其相应厚度也同时增加。

This study is based on SUMO simulation software,referring to the requirements for setting the length of each area in the work area in the"Highway Maintenance Safety Operation Regulations"(JTG H30—2015),and constructing a simulation environment in SUMO.The test conditions are divided into:Closed right single lane.Based on actual operating conditions,the traffic volume and proportion of large vehicles are divided into three situations,and TTC and DRAC are used as evaluation indicators.The experimental results show that under any operating conditions and traffic volume conditions,the positions of the"TTC risk wall"and"DRAC risk wall"formed when vehicles enter the upstream transition zone advance with the increase of the proportion of large vehicles,and their corresponding thickness also increases.
