Vehicle-road cooperation intersection traffic flow conflict resolution method

Abstract

The invention discloses a vehicle-road cooperation intersection traffic flow conflict resolution method, which comprises the following steps: real-time acquisition is performed on intersection full-time-space dynamic traffic information through a vehicle-mounted unit and a road side unit, an intersection control center performs fusion processing on the received traffic data information, driving behavior suggestions are provided for vehicles, the driving state of the vehicle is adjusted in advance in the regulation and control area, the distance between the vehicle and the front vehicle is controlled to the optimal gap, the vehicle is driven into the buffer area and the intersection at a constant speed in the state, and the traffic flow in the conflict direction can alternately pass through the intersection conflict area through the gap, so that conflict resolution is realized. According to the method, the vehicles are not limited by control of traditional signal lamps any more, fixed delay caused by traffic signal control to the vehicles is reduced, the traffic capacity of the intersection and the traffic efficiency of the vehicles are greatly improved on the premise that traffic safety is guaranteed, and space-time resources of the intersection are fully utilized.

Description

technical field [0001] The invention relates to the technical field of vehicle control at road intersections, in particular to a vehicle-road coordinated intersection vehicle flow conflict resolution method. Background technique [0002] Intersections, as the hub nodes of traffic gathering, turning and evacuation, are the concentration of road traffic conflicts and the focus of urban road traffic design and organization management. Therefore, an efficient and reasonable strategy for resolving traffic flow conflicts at intersections is the key to solving the problem of urban traffic congestion, and it is also the bottleneck that restricts the efficiency of urban traffic operations and the capacity of road intersections. [0003] Under the existing technology, in order to ensure the safety of vehicles and smooth driving, the signal light control mode of "stop at red light and go at green light" is generally used at intersections to guide vehicles in all directions to pass in a...

Problems solved by technology

But obviously, this method of conflict resolution cannot achieve every second in terms of signal timing, nor can it achieve every inch of land in traffic channelization, so there is a certain amount of idle time and idle area in the intersection, resulting in the intersection of space-time resources. waste of
