Abstract

The present invention proposes a method and system for dynamic formation of vehicles at an intersection. The method includes: acquiring dynamic information and static environment information in the intersection area; determining lane information in the intersection area according to the static environment information, and converting the The entrance lane is divided into a pre-formation area and a formation area; according to the dynamic information and the lane information, the optimal lane guidance information of each vehicle in the pre-formation area is generated in real time, the pre-formation information based on each lane is generated, and the information based on the formation is generated. Formation decision information is obtained from the formation traffic guidance information of each lane; formation guidance is provided to each vehicle in real time according to the formation decision information and the dynamic information; the formation is terminated according to the traffic flow information and the formation decision-making situation of each vehicle. This method can judge the optimal lane in real time according to the traffic flow information, realize dynamic formation, and most vehicles in the intersection area pass through the intersection in formation, which can improve the efficiency of vehicle formation.

Description

Technical field [0001] The present invention relates to the field of intelligent traffic, and in particular, there is a dynamic formation method and system for intersecting a vehicle vehicle. Background technique [0002] With the rapid development of urbanization and the increasing amount of people's living standards, the number of motor vehicles has grown rapidly, and the traffic congestion in large and medium-sized cities is becoming more serious. Due to the overall correlation of urban traffic network, the congestion of key intersections tends to cause regional traffic jams. [0003] The intersection area generally includes inlet, exit channels, and intersections. Under the instructions of the signal light, the vehicle drove into the intersection from the inlet and exits the intersection from the outlet. The vehicle needs to enter the intersection according to the signal of the signal (such as red light stop, green line), while the driver of the vehicle needs pre-judgment, an...
