The invention discloses a supersaturated traffic state trunk line self-adaptive signal coordination design method and device. The supersaturated traffic state trunk line self-adaptive signal coordination design method comprises the steps of: acquiring geometric parameters, traffic parameters and control parameters of a supersaturated traffic state trunk line target road segment and traffic flow data of a time period needing to be optimized, and generating an initial control scheme and corresponding traffic parameters; acquiring the real-time queuing length of the straight lane at the intersection, and judging whether demand fluctuation occurs or not; when demand fluctuation occurs in a certain period of one intersection, judging whether the influence can be controlled in the period throughstraight-going phase green light duration adjustment, and adjusting the green light duration and corresponding traffic parameters; and judging whether the green light duration adjustment of a branchleft-turn phase can influence and control the green light duration at the intersection, and adjusting the green light duration and the corresponding traffic parameters. The invention provides a trunkline self-adaptive adjustment strategy based on real-time queuing length detection, and the influence of demand fluctuation on a signal scheme is controlled.

    本发明公开了一种过饱和交通状态干线自适应信号协调设计方法与装置,其中方法包括获取过饱和交通状态干线目标路段的几何参数、交通参数、控制参数以及需优化时段的交通流量数据,生成初始控制方案及对应交通参数;获取交叉口直行车道实时排队长度,判断是否出现需求波动;当某交叉口某周期出现需求波动时,判断能否通过直行相位绿灯时长调整将影响控制在本周期,调整绿灯时长及对应交通参数;判断能否通过支线左转相位绿灯时长调整将影响控制在本交叉口,调整绿灯时长及对应交通参数。本发明提出一套基于实时排队长度检测的干线自适应调整策略,控制需求波动对信号方案的影响。
