摘要
通过实地调查和查阅相关资料的方法确定了我国山区长大下坡公路交通事故的主要车型和紧急避险车道的设计车速。以保证制动失效车辆行驶时的横向稳定性为前提,以主线为右转曲线的公路为主要研究对象,通过制动失效车辆由主线驶入紧急避险车道的行车轨迹几何特征对紧急避险车道驶入角和主线平曲线半径之间的关系进行了研究,得出了适合我国山区紧急避险车道驶入角的合理取值范围。为我国山区公路紧急避险车道驶入角的选取提供了必要的理论参考。
Field investigation and access to relevant information were used to determine the main vehicle style of traffic accidents on the long and steep downgrade mountain road in our country and the speed of truck escape ramps.In order to ensure the lateral stability of vehicles in traveling,the relationship between the angle to truck escape ramps and the radius of the main line flat curves,with main line turning right as the main study object was researched through the track geometry characteristics of brake failure vehicles from mainline pass into truck escape ramps.Finally reasonable range of truck escape ramps angle was established,which provided a necessary theoretical reference for selecting the angle to truck escape ramps of mountain roads in our country.
