摘　　要：信号控制交叉口进口道存在车辆掉头行驶的需求,不同的道路条件及交通状况下,掉头车辆所需的掉头条件也不同。为确定合适的信号交叉口进口道掉头设计条件,使车辆能够安全有序地通行,在仿真车辆掉头行为的基础上,分析车辆运行轨迹特性,建立了掉头空间计算判别模型;同时基于信号交叉口车辆排队及换道理论模型,建立了掉头设置位置计算模型。最后选取一实例对上述两个模型进行验证,结果表明模型精度较高,计算方法可行。There is a demand for U-turn at intersections of signal controlled intersections. The U-turn conditions required for U-turn vehicles vary with different road and traffic conditions. To determine the appropriate U-turn design conditions at the entrance of the signalized intersection so that vehicles can pass safely and orderly, based on the simulation of the U-turn behavior of the vehicle, the characteristics of the vehicle trajectory are analyzed and a U-turn space discriminant model is established. Based on the theoretical model of vehicle queuing and lane change at signalized intersections, a calculation model for the U-turn setting position is established. Examples are chosen to verify the above two models. The results demonstrate that the models have high precision and the calculation methods are feasible.
