Intersection phase scheme optimization method based on lane division and flow distribution

The invention discloses an intersection phase scheme optimization method based on lane division and flow distribution. The intersection phase scheme optimization method comprises the following steps: 1, determining a feasible solution space of an intersection phase scheme by lane division; 2, calculating a key traffic flow total flow ratio of each phase scheme in the feasible solution space; 3, determining an optimal intersection phase scheme. According to the intersection phase scheme optimization method based on lane division and flow distribution provided by the invention, the optimal phase scheme can be selected from the alternative phase schemes, so that the signal cycle length calculated based on the optimal phase scheme is smaller; besides, the vehicle delay time and the queuing length can be obviously reduced by the smaller signal cycle, and therefore, a better signal control effect can be obtained. 本发明公开了一种基于车道划分和流量分布的交叉口相位方案优选方法，包括以下步骤：步骤1：由车道划分确定交叉口相位方案的可行解空间；步骤2：计算可行解空间中每种相位方案的关键车流总流量比；步骤3：确定交叉口最佳
