摘要
交叉口是公路网络中的基本节点,其型式对交通运行状况与交通安全有着重要的影响。由于受多种因素的影响,目前公路网络中存在一定数量的Y型交叉口,这种畸形交叉口的存在,既降低了车辆运行效率,又容易引发交通事故。因此,从Y型交叉口的冲突点分析入手,对Y型交叉口的改造设计方案作一研究,这对于正确合理地进行交叉口渠化设计和交通组织,以及充分发挥道路网整体交通功效具有重要的意义。
Inter sections are basic joints of highway network and their models influence traffic operation and safety greatly. As affected by many factors, there are a number of Y-model intersections in highway network. The existence of such abnormal intersection lowers operation efficiency and triggers accidents.So analyzing the conflict points of Y-model intersections and further studying transformation design of Y-model intersections which is of great significance to operate correct and reasonable manner intersection drainage design and traffic organizations, and to play the overall road framework traffic effectively.
