The invention provides a control system and a control method for road network road traffic signals. The system comprises master control devices and slave control devices, wherein each master control device and at least two slave control devices form a control body; the slave control devices are provided with traffic signal indicating lamps; and the master control device in each control body controls the state of the traffic signal indicating lamps of the slave control devices in the same control body based on a generated regulation and control signal. The method comprises the following steps of arranging the slave control devices at predetermined intersection positions of a road network, moving the master control devices to a target intersection, generating regulation and control signals of the slave control devices corresponding to different traffic directions based on traffic flows of different traffic directions in different time periods, and taking a next intersection needing traffic signal control as the target intersection. According to the control system and the control method, distributed dynamic control of road traffic is realized in a dynamic wireless ad hoc network mode, and the hardware cost is saved.
本发明提出路网道路交通信号的控制系统与控制方法。系统包括主控制装置和从控制装置,每个主控制装置和每至少两个从控制装置构成控制体;从控制装置配置交通信号指示灯;控制体内的主控制装置基于生成的调控信号控制同一控制体内的从控制装置的交通信号指示灯的状态。方法包括将在路网的各个预定路口位置布置从控制装置,将主控制装置移动至目标路口,基于不同通行方向的在不同时间段的交通流量,生成各个不同通行方向对应的从控制装置的调控信号后,将下一个需要进行交通信号控制的路口作为目标路口。本发明通过动态的无线自组网方式实现了道路交通的分散式动态控制,且节约了硬件成本。
