DYNAMIC REGULATION METHODS FOR LANE CHANGING DECISION POINT OF CAV DEDICATED LANE IN DIVERGING AREA OF EXPRESSWAY

Disclosed is a dynamic regulation method for a lane changing decision point of a CAV dedicated lane in a diverging area of an expressway, applied to the diverging area of the expressway in which the CAV dedicated lane is provided at an inner side of a road. Vehicles traveling in the CAV dedicated lane are all CAVs. Both the CAVs and human-driven vehicles can travel in ordinary lanes. The method calculates the lane changing decision points of diversion vehicles in the CAV dedicated lane at current time using corresponding algorithms based on a relationship between the lane changing decision points of the CAV dedicated lane and traffic efficiency and a traffic safety. The dynamic regulation method of the present disclosure improves the traffic operation condition of the diversion region, improves traffic efficiency and traffic safety of the diversion region, and reduces fuel emissions, thereby providing a method support for the traffic flow control in the diverging area of the expressway under the setting condition of the CAV dedicated lane.
