摘　　要：现有道路交通信号控制系统已难满足现今的智能化趋势。通过设计CAN通信和以太网通信双层架构,实现了大容量信息的高效传输以及信号灯控制和车辆信息的实时交互。通过灯组监控模块设计,实现了信号灯的双重管控,在信号灯或其控制系统出现故障时,确保实时执行方案降级或独立黄闪控制。以上高效通信和双重管控策略有效提高了道路交通信号控制系统运行质量,为智能交通的发展提供了理论基础。Existing traffic signal control system is already difficult to meet the current trend ofintelligence.Through design of dual layer architecture with CAN and Ethernet communication,highefficient transmissions of big data as well as real-time interaction of signal light control and automobileinformation are realized.Through the module design on light group surveillance,dual control on the signallight is realized so that real-time implementation of program degrade or independent yellow flash controlwill be stimulated along with failure on signal light or its control system.The efficient communicationand dual control strategy above can effectively improve the quality of traffic signal control system,andprovide a theoretical basis for the development of intelligent traffic.
