摘　　要：交通系统中车辆的控制一直是被广泛关注的话题,如何灵活控制信号灯,并且使车辆控制达到最优化的效果,这需要综合运用现代电子技术与通讯技术等手段来实现交通运输.FPGA系统由于其自身的并行结构,有着相对灵活和高速处理数据的优势,本设计通过用VHDL硬件电路描述语言编程,完成倒数计时器和状态转换等程序设计,实现对LED灯及7段数码管的直接控制,最后在Quartus II软件平台下进行编译和仿真,并通过Cyclon系列器件模拟实现,解决了使用单片机引脚有限的问题,使FPGA在信号灯控制中发挥了重要作用.The vehicle control in transportation system has been a widely concerned topic, u- sing a flexible method to optimize the vehicle system control, which requires the integrated use of modern electronic technology and communication technology and other means to a- chieve. Due to the parallel structure in the FPGA system, it has advantages of relatively flex- ible system and high-speed data processing. This design use the wide used VHDL hardware description language in the programming, then design a countdown timer and a state transi- tion program and so on, using these to achieve real time control of an intelligent transporta- tion system at the intersection signal lamp. Finally, using Quartus II software platform process the design files and simulation by Cyclone series. It solved the problem of the limited
