摘　　要：早期平面交叉路口交通信号控制系统研究是建立在单片机或EDA芯片和QuartusⅡ软件基础上,难以满足城市交通控制和电子技术发展需求。该研究根据现有平面交叉路口交通信号控制的实际情况,采用了新一代FPGA芯片,在目前流行的Vivado2018软件基础上,使用Verilog语言设计完成;首先分析了交通信号控制系统的设计需求和策略,提出基于FPGA交通信号控制系统新设计方案,并对交通信号控制系统新方案中信号灯控制方法和交通信号倒计时方法进行了深入的讨论,然后对平面交叉路口交通信号进行仿真和比较实验。实验结果显示该方法具有较高的可靠性和较好的工作效率。The early research of traffic signal control system at level crossing is based on MCU or EDA chip and Quartus Ⅱ software,which is difficult to meet the needs of urban traffic signal control and electronic technology development.According to the reality of the existing of traffic signal control at level crossing,this research adopts a new generation of FPGA chip,and finally finished by using verilog language based on the current popular vivado 2018 software.Firstly,the design requirements and strategies of the traffic signal control system are analyzed,and a new design scheme of the traffic signal control system based on FPGA is proposed.The signal control method and traffic signal countdown method in the new scheme of the traffic control system are discussed in depth.Finally,the simulation and comparison experiments are carried out on the traffic signals of the intersection,and the results show that it has higher reliability and better efficiency.
