The invention discloses a signal lamp control method compatible with four-way temporary passage on a bridge crossing section, and belongs to the field of traffic vehicle passage control. On one hand, the concepts of a normal demand and a temporary demand are introduced, so that the north-south vehicles (up-and-down vehicles) and the east-west vehicles (transverse vehicles) are subjected to clear passing time division; the passing time period is defined by judging whether the time interval from the next normal demand is larger than the time consumed for completing the temporary demand or not, so that vehicles getting on and off the bridge can freely pass in any time period, and transverse vehicles can pass in the former interval time period. Vehicles getting on and off the bridge directly pass through the cross-shaped road section without deceleration, so that the current blocking situation can be greatly relieved. And on the other hand, the four temporary directions are divided into the queue A and the queue B, and the passing sequence is determined according to the quantity, so that the problem that the existing scheme cannot solve the problem of simultaneous passing in the four directions is solved, three special condition processing schemes are provided, and resources are reasonably allocated.
本发明公开了上桥十字路段兼容四向临时通行的信号灯控制方法,属于交通车辆通行控制领域。一方面,本发明通过引出常态需求和临时需求的概念,对南北向车辆(上下桥车辆)和东西向通行(横向通行)车辆进行明确的通行时段划分,通过“判断距离下一次常态需求来临的时间间隔是否大于完成此次临时需求所费时间”的方式来界定通行时段,以实现“上下桥车辆可在任意时段自由通行,横向车辆可在前者间隔时间段内通行”,上下桥车辆在十字路段处不减速直接通过就能够大幅度缓解堵塞现状。另一方面,通过将四个临时方向分成A队和B队,采用按数量大小决定先后通行顺序的方式,克服了现有方案无法解决四向同时通行的问题,还给出了三种特殊情况的处理方案,合理分配资源。
