The invention provides a traffic signal intersection anti-overflow control system and method based on a color step table, and belongs to the technical field of traffic signal control, and the system comprises an overflow detection configuration subsystem, an overflow detector subsystem, a color step table subsystem, a signal control subsystem, a rear-end prediction analysis subsystem and a rear-end overflow shunting subsystem. The overflow detector subsystem detects the vehicle passing state of the road intersection exit to judge the overflow degree, and the overflow flow direction and the corresponding time proportion chain are inquired from the overflow detection configuration subsystem with the overflow degree as a parameter. And inquiring the variable pace and variable duration of the overflow flow direction from the color step table subsystem by taking the overflow flow direction as a parameter, and shortening the traffic flow of the overflow flow direction by taking the value corresponding to the time proportion chain configuration as the proportion of variable pace duration adjustment. The signal lamp is adjusted according to the congestion information of each intersection, flexible control of the signal lamp is realized, and the technical problem of poor flexibility of a signal lamp control mode in the prior art is solved.

    本发明提供了一种基于色步表的交通信号路口防溢出控制系统及方法,属于交通信号控制技术领域,本发明包括溢出检测配置子系统、溢出检测器子系统、色步表子系统、信号控制子系统、后端预测分析子系统和后端溢流分流子系统。溢出检测器子系统对道路交叉口出口车辆通行状态的检测判断溢出程度,以溢出程度作为参数从溢出检测配置子系统查询到溢出流向和对应时间比例链,以溢出流向作为参数从色步表子系统中查询到此溢出流向的可变步伐和可变时长,以所述对应时间比例链配置的值作为可变步伐时长调节的比例,缩短溢出流向的车流。根据各路口的拥堵信息调整信号灯,实现了信号灯的灵活控制,解决了现有技术中信号灯控制方式灵活性差的技术问题。
