摘要
用VHDL和有限状态机的方法设计了主干道与支干道的交叉路口交通信号灯无人自动管理的控制系统。将路口红绿灯的各种亮灯情况定义不同的状态,路口状况定义为触发条件,组成有限状态机。基于此模型的交通信号灯控制系统可充分利用现有交通资源,缓解城市交通压力。
The automatic traffic light controlling system for the crossing consisted of a highway and a farmroad was designed by using VHDL and finite state machine.In the design,the light phase of the green and red light was defined as the state,and the situation of the crossing was defined as the condition,which form a finite state machine.The traffic light controlling system based on the model can make full use of the existed traffic resources,and help to lighten the heavy traffic in the cities.
