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。

Abstract: 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.

Key words: traffic design, U-turn setting conditions, queuing theory, lane changing theory, simulation modeling
