Title:
TRAFFIC LIGHT CONTROL METHOD AND RELATED DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/123906
Kind Code:
A1
Abstract:
Embodiments of the present invention provide a traffic light control method, comprising: obtaining state information of a current intersection and an adjacent intersection within a first preset time period, and obtaining a graph structure of the current intersection and the adjacent intersection, the state information comprising a stay position and a stay duration of a vehicle in each lane, and the graph structure comprising a connection relationship between the current intersection and the adjacent intersection; inputting the state information and the graph structure into a pre-trained intelligent agent, and predicting a traffic light action at the current intersection at a preset point in time, the intelligent agent being trained by means of reinforcement learning; and controlling a traffic light at the current intersection to execute the traffic light action at the preset point in time according to the traffic light action at the current intersection at the preset point in time. The traffic light action at the current intersection at the preset point in time is accurately predicted from a space-time dimension by means of the intelligent agent, and then the traffic light at the intersection is controlled to execute the traffic light action at the preset point in time, thereby avoiding vehicle congestion or an idle passing time window and thus improving the passing efficiency of a whole road network.
