摘　　要：交通灯控制系统在城市交通监管中起着极其重要的作用。应用VHDL语言,在Altera公司的Max+PlusⅡ软件环境下,通过模块化编程完成了灯亮时间可调的交通灯控制系统设计,并进行了逻辑综合、仿真和硬件下载,系统的软件仿真和实验测试结果满足了设计要求,达到了预期的效果。由于设计采用了EDA技术,不但大大缩短了开发研制周期,提高了设计效率,而且使系统具有设计灵活,实现简单,性能稳定的特点。The traffic light controller has become an indispensable part of the traffic systems, playing an important role in the traffic supervision. This paper realizes the design of traffic light controller whose flickering times is adaptively changeable with VHDL. The Max＋Plus II software automatically completed the VHDL resource program analysis,logic synthesis,opti mization and device programming. The results of simulation meet scheme design. With EDA technology, the design has the advantages of facility design,convenient operation,high reliability and the design efficiency is also improved.
