The invention provides an intersection saturation disposal method, system and device based on traffic flow, and aims to solve the problem of intersection traffic saturation alarm. The method comprises the following steps: calculating the number of vehicles detained at all congested phases; judging whether an unsaturated phase exists or not; predicting release time required by each phase in the next period and verifying rationality; and outputting an adjustment scheme for the phase time or the detained vehicle. The traffic saturation alarm event at the intersection is responded, the queuing length balance of each phase is taken as a target, the signal scheme is adjusted, and the current situation of intersection congestion is relieved.

    本发明为解决解决路口交通饱和报警的问题,提供一种基于交通流量的路口饱和处置方法、系统及设备,方法包括计算所有拥堵相位滞留车辆数;判断是否存在未饱和相位;预测下一周期各相位所需的放行时间并验证合理性;输出对相位时间或滞留车辆的调整方案。本发明响应路口交通饱和报警事件,以各相位排队长度均衡为目标,调整信号方案,缓解路口拥堵现状。
