  • Publication number: 20240071222
    Abstract: A method for controlling a traffic light, a method and apparatus for navigating an unmanned vehicle and a method and apparatus for training a model are provided. An implementation comprises: generating a reinforced traffic light state parameter according to vehicle state representation information of an unmanned vehicle currently contained in a preset area of a target traffic light and a current traffic light state parameter of the target traffic light; and generating a traffic light control action according to the reinforced traffic light state parameter; where the reinforced traffic light state parameter is used to cause an unmanned vehicle navigation end to generate a reinforced vehicle state parameter according to a reinforced traffic light state and a current vehicle state parameter of a target unmanned vehicle, and generate an unmanned vehicle navigation action according to the reinforced vehicle state parameter.

  • Publication number: 20220227388
    Abstract: A method for determining a green wave speed, an apparatus for determining a green wave speed, and a storage medium is provided. The method includes: obtaining vehicle driving data of at least one vehicle on a green wave coordination line; determining a driving direction of each vehicle based on the vehicle driving data of the corresponding vehicle; determining a vehicle with driving direction matching a green wave coordination direction corresponding to the green wave coordination line as a target vehicle; and determining a green wave speed of a road section between any two adjacent intersections on the green wave coordination line based on the vehicle driving data of the target vehicle.
