The invention discloses a control method of a straight-right variable guide lane considering conflict between pedestrians and right-turning vehicles. The control method switches an entrance lane variable guide lane function between a straight-right lane and a right-turning special lane in due time, and reduces the conflict between a right-turning traffic flow and pedestrians crossing a street under the condition of considering the passing efficiency of a straight traffic flow. The control method mainly comprises the steps of intersection road and traffic information acquisition, right-turningvehicle proportion estimation in a straight-right guide lane, saturated traffic capacity of right-turning traffic flow in green light time, variable guide lane function judgment based on the trafficcapacity of the right-turning traffic flow and the like. According to the control method, the function of the variable guide lane can be converted into a special right-turning function when the conflict between pedestrians crossing the street and right-turning vehicles is increased, straight-going vehicles are prevented from entering lanes with low traffic efficiency, and the traffic operation safety of the intersection is ensured; and when the conflict between the right-turning vehicles and the pedestrians crossing the street is not serious, the variable guide lane can be converted into the straight-right shared lane, so that the space-time resource utilization rate of the road intersection is improved.

    本发明公开了一种考虑行人与右转车辆冲突的直右可变导向车道的控制方法,适时地将进口道可变导向车道功能在直右车道和右转专用车道之间切换,在兼顾直行车流的通行效率下,减少右转车流与过街行人的冲突。本发明方法主要包括交叉口道路及交通信息获取,直右导向车道中右转车辆比例估计,右转车流在绿灯时间内的饱和通行能力,以及基于右转车流通行能力进行可变导向车道功能判定等步骤。本发明能在过街行人与右转车辆的冲突增大时将可变导向车道功能转换为右转专用,防止直行车辆进入低通行效率的车道,保障交叉口交通运行安全。并能在右转车辆与过街行人的冲突不严重时,将可变导向车道转换为直右共用车道,提高道路交叉口的时空资源利用率。
