摘要
为准确评估雨天道路行车安全性,选取雨天时路面附着系数和能见度作为评估指标.应用ADAMS/Car软件,并采用侧向位移差值的仿真方案和制动距离的仿真方案得出关于雨天时附着系数和能见度这两个指标的仿真结果.在结果分析的基础上,建立降雨天气下行车安全评估等级划分方案.
In order to accurately assess the roads' traffic safety of rainfall weather,this paper chooses the road adhesion coefficient and visibility of rainfall weather as the two indicators to study.Then,with the use of ADAMS/Car and the application of the simulation programs: differential value of lateral displacement and of the braking distance,this paper comes to the simulation results on attachment coefficient indicator and visibility indicator in wet weather.On the basis of the analysis results,this paper has established a grading program for traffic safety assessment of rainfall weather.
