The invention provides a dynamic signal optimization method for actively reducing coordination transition adjustment times, and belongs to the technical field of urban road traffic signal control. According to the method, on the basis of the scheme with the unified phase sequence, the transition adjustment state of the scheme is judged according to the period, and a transition adjustment algorithm and a green time ratio and period dynamic optimization algorithm are executed according to the state. According to the method, phase sequences of all intersection release schemes under coordinated control are necessarily adjusted, and coordinated phases are uniformly adjusted to the first stage; and judging a transition adjustment state of the unified phase sequence scheme according to a period, executing a transition adjustment algorithm in a transition state, and executing a green time ratio and period dynamic optimization algorithm in a non-transition state. According to the method, only necessary transition adjustment needs to be executed at the initial stage of algorithm starting, and the green time ratio and the period can be dynamically optimized without transition adjustment when no external interference exists subsequently. The method is suitable for various coordination control scenes such as time-phased coordination control, dynamic green wave induction, regional coordination control and the like, and is wide in applicability.
本发明提供了一种主动减少协调过渡调整次数的动态信号优化方法,属于城市道路交通信号控制技术领域。本发明方法基于统一相序后的方案,按周期判别方案的过渡调整状态,并依据该状态分别执行过渡调整算法、绿信比和周期动态优化算法。该方法对协调控制下所有路口放行方案的相序进行必要调整,将协调相位统一调整至首个阶段;按周期判别统一相序方案的过渡调整状态,过渡状态时执行过渡调整算法,非过渡状态时执行绿信比和周期动态优化算法。本发明仅需在算法启动初期执行必要的过渡调整,后续无外部干扰时,均可无过渡调整的动态优化绿信比和周期。本发明适用于分时段协调控制、动态感应绿波、区域协调控制等多种协调控制场景,适用性广。
