Optimization method of signal timing and vehicle speed dynamic coordination control based on vehicle-road coordination

Abstract

The present invention proposes a signal timing and vehicle speed dynamic coordination control optimization method based on vehicle-road coordination. First, based on the original green wave coordination scheme of the coordinated arterial road, and according to the traffic flow information parameters and the initial detection of the incoming flow of the target fleet on the road section, Calculating the increment of green light time is beneficial to improve the traffic capacity of the coordinated intersection and reduce the queue length of the intersection when the target vehicle traffic increases; according to the actual driving speed of the target vehicle team, combined with the optimal design speed of the original green wave coordination scheme of the coordinated arterial road , to calculate the green light adjustment time of the coordinated intersection, which is beneficial to obtain the maximum green wave bandwidth and minimize the number of parking of straight vehicles. Under the dynamic optimization of timing, the driving behavior of vehicles is adjusted to ensure the efficiency of road traffic.
