摘要
传统交叉口竖向设计考虑交叉口内的排水及行车舒适性,未考虑转弯车辆的安全性,车辆在交叉口内转向行驶容易发生侧滑、倾覆及翻滚等交通事故。为了减少此类交通事故的发生,开展本次研究。基于交叉口内的转向车辆行驶轨迹,从转向车辆的行驶速度、转弯半径、轨迹宽度及超高横坡等角度分析,考虑车辆行驶的安全性、舒适性,对交叉口内的排水方向、特征点位置及高程进行确定,结合实际工程案例验证理论的可行性。
Traditional intersection vertical design considers the drainage and driving comfort in the intersection,but does not consider the safety of turning vehicles.Vehicles are prone to side slip,overturn and rollover accidents when steering in the intersection.In order to reduce the occurrence of such traffic accidents,this research is carried out.Based on the trajectory of steering vehicles in intersections,this paper analyses the speed,turning radius,trajectory width and super-high cross-slope of steering vehicles,considering the safety and comfort of vehicle driving,the drainage direction,the location and elevation of the characteristic points in the intersection are determined.The feasibility of the theory is verified by practical engineering cases,which provides a reference for the vertical design of the intersection.
