Aiming at the defects of the traditional method of computing the left-turn vehicle traffic capacity,the existing model for the gap acceptance at the intersection without traffic signal was improved and a new model was developed for the left-turning crossing the opposite through vehicles with limited priority.
针对传统的左转车通行能力计算方法中存在的问题,对无信号交叉口的可插车间隙理论模型进行了改进,建立了具有部分优先权的可插车间隙理论模型。
