摘　　要：论述一种基于FPGA的交通红绿灯设计方案,可以有效解决城市中十字路口各方向车流量不均衡,特别是同一条道路相对方向车流量不均衡的问题。对相对方向采用不同步的红绿灯信号,减小了十字路口交通资源的浪费情况,实现对交通信号的智能控制,极大提高十字路口的车辆运行效率。This paper discusses a design scheme of FPGA-based traffic lights, which can be an effective solution to unbalanced omnidirec- tional traffic flow on city crossroads, especially to the unbalanced road traffic flow in opposite directions on the road. The intelligent control of traffic signals is realised by using asynchronous signals of traffic lights for opposite directions, which reduces the wastage of traffic resource on crossroads. The traffic efficiency of vehicles on crossroads has therefore been greatly improved.
