信号控制交叉口掉头交通设计研究

针对我国掉头交通通行效率低下和安全性较差等问题,分析了信号控制交叉口掉头交通的掉头时间和冲突点等运作特性,并系统地归纳分析掉头交通的影响因素及其内在联系。根据我国现有掉头交通设计情况,总结了3种掉头交通设计模式,根据掉头车辆的运动原理,提出掉头交通的空间设计要点。最后结合具体操作时存在的问题,提出了详细设计方案。

Research of the U-turn Design in Signalized Intersection

According to the problem of the low efficiency and safety of the U-turn,the paper analyses the time and number of the potential conflict points of the U-turn,and analyses the U-turn traffic impact factors and their internal relations systematically. According to the current situation of U-turn design,the paper summes up three kinds of U-turn design patterns,advances elements of the U-turn space design based on the principle of U-turn movement.Considering the specific operation problems,it suggests detailed ...
