A Novel Virtual Traffic Light Algorithm Based on V2V for Single Intersection in Vehicular Networks

摘要

For the vehicle passing priority, the existing virtual traffic light algorithm only considered the factor of the arrival time, a group of vehicles won't transfer the wayleave until they all pass completely. This method cannot achieve the maximum road traffic throughput capacity. This paper designs a queuing chain model and proposes a virtual traffic lights algorithm for Single Intersection (for short SVTL) based on the queuing chain model, considering comprehensively three parameters: the waiting time of each lane, the length of queue chain and the number of queues. The SVTL algorithm eliminates the phenomenon of waiting in vain basically, saves the waiting time of the vehicle, and avoids unnecessary parking conditions. The simulation shows that the SVTL shortens the average waiting time when the traffic density is high, compared with the Common Traffic Lights (CTL) and the existing virtual traffic light algorithm DVTL, the average speed is increased by 36.9% and 16.2% respectively.
