An intelligent scheduling method for unmanned intersections without traffic lights

Abstract

An intelligent dispatching method for unmanned intersections without traffic lights, including the following steps: Step 1: Set up a traffic manager based on the intersection and dispatch areas and divide collision avoidance areas, and establish a traffic manager as a collaborative vehicle communication and planning vehicle The central control and management mechanism of dispatching; Step 2: The traffic manager receives the driving data of specific vehicles entering the dispatching area, and returns the dispatching information of specific vehicles passing through the intersection; Step 3: According to the guidance of dispatching information, the unmanned vehicles carry out corresponding Adjust to pass through the intersection; the collision avoidance area is the intersection area of ​​two lanes at the intersection, the collision avoidance area is divided into 16 square conflict areas of the same area, and the same square conflict area can only be occupied by one vehicle at most; enter The unmanned vehicles in the collision avoidance zone need to travel at the same constant speed and in a predetermined 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
