摘要
道路平面交叉口作为城市路网系统中的重要节点,其竖向设计是否合理对整条道路的技术指标有着较大的制约。当交叉口位于坡面上时(如桥头接坡),随着道路纵坡值的增加对车辆的行车舒适性有着明显影响。通过对该类交叉口竖向设计进行分析,提出评价指标及优化措施,以改善行车条件,提高行车舒适性。
The plane intersection of road is the important node in the urban road network system. Whether or not reasonable for the vertical design will more greatly restrict the technical indexes of the whole road. The intersection if located on the slope(i.e. the slope connected with bridge head) will obviously influence the driving comfort of vehicle with the increment of road longitudinal slope value. According to the analysis on the vertical design of this kind of intersection, the article puts forward the evaluation index and optimization measures to improve the driving condition and the driving comfort.
