基于DEEC车载分簇的交通灯改进配时方案
An Improved Traffic Light Timing Scheme with DEEC Vehicular Clustering Algorithm
摘要
Abstract
In cellular vehicle-to-everything (C-V2X) system, aiming at the problems of vehicle congestion and queuing at intersections in urban roads, the improved distributed energy efficient clustering (DEEC) clustering algorithm is presented to select the vehicle node with higher energy of remaining node as the cluster head for improving the survival time of the cluster and utilize the relay vehicle to transmit information for reducing vehicle communication delay. At the same time, the improved Webster traffic light timing algorithm is used to conduct the corresponding signal phase scheduling and cycle timing, and thus reducing the waiting time of vehicles. Finally, the VISSIM traffic simulation modeling software verifies that Webster traffic light improved timing algorithm can reduce vehicle waiting time at intersections and alleviate traffic congestion on urban roads. Numerical simulation results show that the proposed scheme can decrease the communication delay, reduce the waiting time of vehicles and alleviate the urban traffic congestion.关键词
