System for automatically keeping green wave phase difference among multiple road intersections
System for automatically keeping green wave phase difference among multiple road intersections
The invention discloses a system for automatically keeping green wave phase difference among a plurality of road intersections, which comprises a plurality of signal lamp banks, an Ethernet and a traffic command center, and is characterized in that the signal lamp banks are sequentially positioned at the road intersections, and the signal lamp banks and the road intersections form a first green wave band intersection and a second green wave band intersection. According to the method, a starting intersection for initiating a green wave band is set as a green wave initiating intersection, time periods and phases set at other intersections all take the intersection as a reference, analysis and calculation are carried out according to parameters such as actual road length and driving speed, corresponding phase duration and corresponding time offset are set, and the green wave band is started while the green wave band is started. The automatic phase difference keeping mechanism between the intersections is started, so that even if the actual phase starting time of a certain intersection is deviated from the preset phase starting time due to various reasons, the deviation can be gradually reduced by automatically prolonging or shortening the phase duration, and real unattended green wave band control is realized.
本发明公开了一种自动保持多个道路交叉口之间绿波相位差的系统，包括信号灯组、以太网和交通指挥中心，信号灯组的数量为若干组且依次位于道路的交叉口处，信号灯组与道路交叉口形成第一绿波带路口、第二绿波带路口。本发明将发起绿波带的起始路口设置为绿波发起路口，其它路口设置的时段、相位均以该路口为基准，按照实际道路长度、行车速度等参数进行分析计算，设置相应的相位时长和相应的时间偏移量，启用绿波带的同时，启用路口之间的自动保持相位差机制，这样，即使某个路口应为种种原因导致实际的相位启动时间与预设的相位启动时间有偏差，也可以通过自动的延长或者缩短相位时长逐步的降低这种偏差，实现真正的无人值守的绿波带控制。
