The invention belongs to the technical field of traffic engineering, and particularly relates to a one-two-three one-way traffic intersection shift left-turn signal optimization control method and system. The method comprises the following steps: step 1, carrying out current situation investigation on the intersection, and dividing lane functions of each entrance lane of the one-two-three one-way traffic intersection according to vehicle passing data in each flow direction; 2, determining the length of a shift left-turn lane of the two-way traffic entrance and exit lane and the length of a left-turn vehicle lane changing section of a road section; 3, determining phases and phase sequences of the main signal and the pre-signal, and determining a coordination design scheme of the main signal and the pre-signal; step 4, based on a stop line and signal control space-time movement, establishing a shift left-turn intersection motor vehicle delay model; and step 5, determining a shift left-turn intersection signal optimization control model and a solving algorithm. By adopting the method, the problems of traffic jam, overlong queuing, relatively high traffic delay and the like at the one-to-two-three one-way traffic intersection during peak hours are solved.

    本发明属于交通工程技术领域,具体涉及一双三单向交通交叉口移位左转信号优化控制方法及系统。所述方法包括以下步骤:步骤1、对交叉口进行现状调查,根据各流向的车辆通行数据,对一双三单向交通交叉口各进口道的车道功能进行划分;步骤2、确定双向交通进出口道移位左转车道长度及路段左转车辆变道段长度;步骤3、确定主信号和预信号的相位、相序,确定主信号与预信号协调设计方案;步骤4、基于停止线及信号控制时空移动,建立移位左转交叉口机动车延误模型;步骤5、确定移位左转交叉口信号优化控制模型及求解算法。采用上述方法,解决了一双三单向交通交叉口高峰小时交通拥堵、排队过长、交通延误较高等问题。
