Right pre-signal control method for turning lane at road intersection
The invention discloses a right pre-signal control method for a U-turn lane at a road intersection, and belongs to the technical field of traffic management and control. The road intersection turn-around lane right pre-signal control method comprises the following steps: step 1, stipulating a running rule that a pre-signal system controls vehicles on a rightmost lane and an adjacent straight lane; 2, coordinating main signal time and pre-signal time according to the specific condition of the signal intersection; step 3, according to a road speed limit value condition, obtaining values of a distance S and a distance L so as to determine a setting position of a pre-signal and a position of a traffic marking; and 4, determining the green light turn-on time and the red light turn-on time of the pre-signal lamp of the turning-around vehicle according to the setting positions of the pre-signal lamp and the traffic marking. According to the method, the limitation of road red lines on vehicle turning can be broken through, intersection space-time resources are fully utilized, safe vehicle turning at the intersection where turning cannot be achieved is achieved, and the overall traffic capacity of the intersection can be improved by controlling the right-turn pre-signal lamp and the turning-around pre-signal lamp.
本发明公开了道路交叉口掉头车道右置预信号控制方法，属于交通管理与控制技术领域。该道路交叉口掉头车道右置预信号控制方法包括：步骤一：规定预信号系统控制最右侧车道及其紧邻直行车道上车辆的运行规则；步骤二：根据信号交叉口具体情况，协调主信号时、预信号时；步骤三：根据道路限速值条件，取得距离S和距离L的值，用以确定预信号的设置位置和交通标线的位置；步骤四：根据预信号灯、交通标线的设置位置，确定掉头车辆预信号灯绿灯启亮时间和红灯启亮时间。本发明能够冲破道路红线对车辆掉头的限制，充分利用交叉口时空资源，在无法实现掉头的交叉口实现车辆安全掉头，并通过控制右转预信号灯和掉头预信号灯，可提高交叉口整体通行能力。
