【摘要】：针对信号交叉口调头区域设置不合理的问题,选择传统四相位控制交叉口为研究对象,基于通行效率最优提出了最佳调头位置的计算方法.该方法首先通过建立左转与调头共用车道的损失时间模型,揭示了左转和调头车流在不同交通条件下的相互影响机理;其次基于不同流向车辆的概率分布函数,构建了信号交叉口左转与调头共用车道的通行能力计算模型,揭示了调头位置对共用车道通行能力的影响特征;最后以淄博市中心城区为例进行了实例分析.实验结果表明,该方法能使左转与调头共用车道的通行能力由432 pcu/h提升到509 pcu/h,提高了17.82%.
[Abstract]:Aiming at the unreasonable setting of turn-off area at signalized intersection, the traditional four-phase controlled intersection is chosen as the research object. Based on the optimal traffic efficiency, the calculation method of optimal turn-off position is put forward. Firstly, by establishing the loss time model of left-turn and turn-over shared lane, the interaction mechanism of left-turn and turn-over traffic flow under different traffic conditions is revealed. Secondly, based on the probability distribution function of different flow direction, the capacity calculation model of left turn and turn-over shared lane at signalized intersection is constructed, and the characteristic of the influence of turning position on the capacity of shared lane is revealed. Finally, taking the city center of Zibo as an example, an example is given. The experimental results show that this method can increase the traffic capacity of the shared lane between left turn and turn from 432 pcu/h to 509 pcu/h, by 17.82%.
