Intersection-based V2P collision avoidance method

Abstract

The invention discloses an intersection-based V2P collision avoidance method comprising the steps that firstly, the participants of the game are ensured to be vehicles and pedestrians, and the participants are classified to define their passing strategy sets; secondly, street crossing delay and risk payment of the vehicles and the pedestrians of the intersection are solved and a V2P game model is established; thirdly, traffic reward and punishment payment is added on the basis of delay and risk payment so as to enhance the priority rate of the vehicles; and fourthly, an SEIR virus propagation model is improved, and an IEVRI model is established to analyze the psychology of the traffic participants so as to prove the necessity of introducing traffic rewards and punishments. The pedestrian flow and the vehicle flow in the traffic flow, the distance and the speed of the pedestrians and the vehicles from a decision area to a conflict area and the relative potential of the number of the unit batch of street crossing pedestrians are integrally considered, and the traffic reward and punishment factors are added and the V2P game model is established so that the road traffic safety can be enhanced and the passing efficiency can also be guaranteed.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to an intersection-based V2P collision avoidance method. Background technique [0002] According to the report of the World Health Organization's global road safety status, 1.24 million people die in traffic accidents every year, and 50 million people are disabled, of which 22% are pedestrians, and about 20% of traffic accidents occur at crossroads. Due to the large population of our country, there is a serious phenomenon of people and vehicles mixed in the traffic system, which increases the traffic conflict between vehicles and pedestrians. With the large-scale application of 4G LTE technology and the popularization of smart phones, using existing network technology It realizes human-vehicle interaction and reduces traffic accidents, which is more active and effective than traditional collision avoidance methods. [0003] In order to solve the vehicle-to-pedest...

Problems solved by technology

The process of information interaction between vehicles and pedestrians crossing the street is also a game process. Many domestic researchers use repeated games to establish driver behavior models at unlit intersections and give vehicles reasonable traffic decisions. However, repeated games increase the risk of collisions and increase traffic efficiency. Low, some people also proposed a dynamic game model of non-cooperation between drivers and pedestrians crossing the street. Time delay and risk-benefit were considered in the game but not quantified
