摘要
分析左转车辆对交叉口车辆运行的较大影响,研究利用左转车辆远引技术实现交叉口车辆左转的交通组织设计方法。建立了左转车辆远引交叉口中央回转开口与主交叉口距离、中央开口半径和通道宽度几何参数的计算模型和公式,经实例计算,给出了有关参数和建议值。分析表明,左转车辆远引技术可以消除交叉口处车辆的左转,从而减少了交叉口信号控制的相位数,降低了直行车辆的延误,提高了交叉口通行能力和干路车流的连续性。
With analyzing the serious impact of left-turn vehicles on intersection,it is studied that the design method of traffic organization by using of vehicles leftdirection for carrying out left-turn vehicles on intersection. Meanwhile,the calculating models and referenced values of geometric parameters about distance from intersection to U-turn hatch in center isolation,turn radius,and path width are built. The analysis results indicate the technique of vehicles left-direction can avoid left-turn vehicles on intersection,reduce phase numbers of the traffic signals and decrease delay to enhance capacity and continuity of the trunk road traffic.
