The invention discloses a bottleneck intersection group signal control optimization method for traffic overflow, and belongs to the technical field of calculation, reckoning or counting. Comprising the following steps: S1, calculating an overflow safety distance; s2, judging and grading controllable nodes according to the association degree of each intersection connection road section and the overflow road section and the residual queuing length; s3, calculating the traffic volume needing to be adjusted in queue congestion of the overflow road section, and carrying out flow distribution according to the residual capacity of each road section; and S4, executing a green time ratio adjusting algorithm or a jump type phase algorithm so as to optimize the phase difference. According to the method, the traffic conditions and the correlation degree of the bottleneck intersection group and the traffic overflow road section are comprehensively considered, the controllable nodes are judged and graded, the signal regulation and control scheme of the related controllable nodes is obtained, the overflow road section is finally defibered, and the traffic efficiency is improved.

    本发明公开了一种面向交通溢流的瓶颈交叉口群信号控制优化方法,属于计算、推算或计数的技术领域。包括如下步骤:S1、计算溢流安全距离;S2、根据各交叉口连接路段与溢流路段的关联程度和剩余排队长度进行可控节点的判断与分级;S3、计算溢流路段排队拥堵需调节交通量并根据各级路段的剩余容量进行流量分配;S4、执行调整绿信比算法或跳跃式相位算法以有优化相位差。本发明综合考虑瓶颈交叉口群与交通溢流路段的交通情况与关联程度,进行可控节点的判断与分级,得出相关可控节点的信号调控方案,最终实现溢流路段的疏解,提高交通效率。
