Traffic light-free intersection intelligent dispatching method for unmanned driving

Abstract

The invention discloses a traffic light-free intersection intelligent dispatching method for unmanned driving, which comprises the following steps: 1, an intersection-based traffic manager and a dispatching area are set, a collision avoidance area is divided, and a center control management mechanism with the traffic manager to coordinate vehicle communication and plan vehicle dispatching is built; 2, the traffic manager receives driving data of a specific vehicle entering the dispatching area, and the dispatching information for passing across the intersection is returned to the specific vehicle; and 3, according to guidance of the dispatching information, an unmanned vehicle is correspondingly adjusted to pass across the intersection, wherein the collision avoidance area is a cross areaof two lanes at the intersection and is divided to 16 square conflict areas with the same area, and the same square conflict area is only occupied by one vehicle at most; and the unmanned vehicle entering the collision avoidance area needs to drive at the same constant speed and in a set direction.

Description

technical field [0001] The invention belongs to the technical field of Internet of Vehicles, and relates to a method for optimal vehicle dispatching and capacity optimization oriented to intersection traffic in a state information-based vehicle control strategy. Background technique [0002] With the development of wireless communication, unmanned vehicles can use dedicated short-range communication (DSRC) technology to realize communication connection and information interaction between vehicles and vehicles, vehicles and infrastructure, etc. These unmanned vehicles connected to each other through wireless communication can reduce most collisions in the transportation system, reduce traffic delays, greatly improve traffic management efficiency, and provide infotainment and telematics functions. Therefore, interconnected unmanned vehicles have great potential for improving traffic system management capabilities, and their advantages make them one of the current research hots...

Problems solved by technology

The traditional traffic light scheduling method can adjust the traffic flow at the intersection to a certain extent, but there are many defects as follows: it cannot adapt to the real-time traffic flow flexibly and intelligently; it lacks the communication and coordination function with unmanned vehicles; resulting in traffic congestion and safety issues; it is difficult to improve the throughput of the entire transportation system and the efficiency of traffic management

[0006] In summary, the existing problems in the existing technology are: (1) The improved intelligent traffic light dispatching system cannot fully utilize the advantages of interconnected unmanned vehicles to improve traffic management capabilities

(2) Most of the new dispatching algorithms in scenarios without traffic lights have a single function and are limited to their specific vehicle driving rules (3) In the process of adjusting the driving state of the vehicle, it is extremely dependent on the reliability of communication and the strength of unmanned driving technology. stability
