The invention discloses an inductive control method based on green wave bandwidth constraint, and the method comprises the steps: firstly taking a coordination phase as a demarcation point, and dividing all phases in a signal control period into a phase before coordination, a coordination phase and a phase after coordination; then, based on constraints of a signal control period and a green wave bandwidth, respectively establishing phase green light upper and lower limit calculation models for three phase types; and finally, sequentially performing inductive control on each phase of the signal control period based on the calculated upper and lower limits of the green light. According to the method, the green wave bandwidth of the main road can be ensured, the phase green signal ratio can be automatically adjusted according to the traffic demand, and the travel efficiency of vehicles and the operation efficiency of the intersection are effectively improved.
本发明公开了一种基于绿波带宽约束的感应控制方法,该方法首先以协调相位为分界点,将一个信号控制周期内的所有相位划分为协调前相位、协调相位,以及协调后相位;然后,基于信号控制周期及绿波带宽的约束,面向三种相位类型分别建立相位绿灯上下限计算模型;最后,基于计算得出的绿灯上下限依次对信号控制周期的各相位执行感应控制。本发明的方法能够在保证主干道绿波带宽的同时,根据交通需求自动调整相位绿信比,有效提高车辆的出行效率及交叉口的运行效率。
