Design method for far leading and turning around of straight-going and right-turning vehicles on secondary road at plane intersection
The invention discloses a plane intersection secondary road straight-going and right-turning vehicle far-leading U-turn design method. The method comprises the following steps: firstly, carrying out space design and facility configuration on an intersection plane area, namely designing a secondary road direction lane function, a left-turn waiting area and a left-turn diversion line, and arranging a main road pedestrian crossing stop area and configuring signal lamps; designing a far-leading U-turn opening, including determining the specification, the type and the opening position of the far-leading U-turn opening; and finally, designing intersection traffic operation and control schemes, including intersection traffic operation scheme design, intersection phase scheme, key lane flow ratio of each phase and signal timing parameter determination. According to the method, streamlines of straight-going and right-turning vehicles in the secondary road direction are redesigned, and meanwhile, a street-crossing streamline of pedestrians on the main road is completely separated from a motor vehicle streamline, so that the traffic organization of a functional area of the intersection can be simplified, and the lane changing times of the turning-around vehicles in the advancing process are reduced; and the overall efficiency and safety level of the traffic flow of the secondary road and the intersection are improved.
本发明公开了平面交叉口次路直行、右转车辆远引掉头设计方法。首先对交叉口平面区域进行空间设计及设施配置，包括次路方向车道功能、左转待行区、左转导流线设计，以及主路行人过街驻足区布置及信号灯配置；然后进行远引掉头开口设计，包括远引掉头开口规格、型式以及开口位置确定；最后是对交叉口交通运行及控制方案设计，包括交叉口交通运行方案设计，交叉口相位方案、各相位关键车道流量比以及信号配时参数确定。该方法对次路方向直行、右转车辆的流线进行了重新设计，同时将主路上行人的过街流线与机动车流线完全分离，能够简化交叉口功能区的交通组织，降低掉头车辆在行进过程中的变道次数，提高次路以及交叉口交通流的整体效率及安全水平。
