The invention relates to the field of traffic signal control, and discloses a traffic signal optimization control method and device. Traffic flow data of an intersection signal system, historical traffic flow data captured by electronic police at intersections and cross-section traffic flow data of the intersections are obtained; the data is pretreated, and training samples are extracted; based onthe training samples, reinforcement learning is carried out to generate a traffic light timing plan; according to the traffic light timing plan, the traffic light control is performed. The accuratesignal control time is achieved, the urban road traffic congestion caused by the time control problem of a traffic signal is effectively alleviated, thus a series of problems of fuel saving, vehicleconsumption and air pollution of automobiles are solved, and the method and the device has great social and economic value.
Description
technical field [0001] The invention relates to the field of traffic signal control, in particular to a traffic signal optimization control method and device. Background technique [0002] The most representative and effective urban road traffic signal control systems widely used in the world at present include the British TRANSYT and SCOOTS traffic control systems and the Australian SCATS system. In the development process of signal control, adaptive control theory has always been respected by various regions as the highest level of signal control, and foreign countries still prefer to use adaptive theory to solve traffic signal control problems. [0003] In recent years, the operation of these signaling systems in China has also achieved satisfactory results. Many high-tech companies in China have developed signal control systems with independent intellectual property rights, such as Hisense's signal control system and signal controller, in terms of control mode, emergenc...
