  • Systems and methods for determining traffic information of a region
    Patent number: 11676485
    Abstract: The present disclosure relates to systems and methods for determining traffic information of a region. The method may include determining a first region and a second region. The method may also include obtaining a set of links associated with the first region and the second region. The method may also include obtaining a plurality of driving routes of a plurality of vehicles in the first region and the second region in a predetermined time period. The method may also include selecting one or more driving routes that traverse a first boundary of the first region and a second boundary of the second region based on the set of links associated with the first region and the second region. The method may also include determining traffic information of the first region based on information related to the one or more selected driving routes.

  • METHOD AND SYSTEM FOR DETERMINING WHETHER THERE IS TARGET ROAD FACILITY AT INTERSECTION
    Publication number: 20200134325
    Abstract: The present disclosure provides a method, system, device, and storage medium for determining whether there is a target road facility at an intersection. The method may include: obtaining trajectory data related to left-turn trajectories of moving objects at a target intersection; extracting information related to feature parameters associated with the target road facility from the trajectory data; determining whether there is the target road facility at the target intersection based on the information related to the feature parameters of the target intersection. The method may determine the road facility configuration of an intersection intelligently, reducing costs of human resources and time.
