The invention relates to the technical field of urban road traffic signal control, and particularly discloses a traffic artery signal coordination control rapid transition adjustment method which comprises the following steps: when an intersection prepares to be switched from a current signal lamp timing scheme to a coordination signal lamp timing scheme, obtaining the interval time between the scheme switching moment of the intersection and the end moment of the last signal period of the current signal lamp timing scheme; judging whether the signal period of the transition signal lamp timingscheme is prolonged or shortened according to the interval time, and executing the transition signal lamp timing scheme within the prolonged or shortened signal period of the transition signal lamp timing scheme; and after the execution of the transition period is completed, starting to carry out coordination control on the intersection according to the coordination signal lamp timing scheme. According to the traffic artery signal coordination control rapid transition adjustment method provided by the invention, the transition of the trunk signal coordination scheme can be completed in one transition period, and the influence on the intersection operation in the trunk signal coordination scheme switching process is greatly reduced.
本发明涉及城市道路交通信号控制技术领域,具体公开了一种交通干线信号协调控制快速过渡调整方法,包括:当交叉口准备从当前信号灯配时方案切换到协调信号灯配时方案时,获取交叉口的方案切换时刻与当前信号灯配时方案最后一个信号周期结束时刻的间隔时间;根据间隔时间判断过渡信号灯配时方案的信号周期是延长还是缩短,并在延长后或者缩短后的过渡信号灯配时方案信号周期内执行过渡信号灯配时方案;当过渡周期执行完成后,开始依据协调信号灯配时方案对交叉口进行协调控制。本发明提供的交通干线信号协调控制快速过渡调整方法能够在一个过渡周期内完成干线信号协调方案的过渡,大大减少干线信号协调方案切换过程中对交叉口运行的影响。
