智能交通平台设计

摘要
该设计以金属传感器作为车辆感应器置于路面下,监测车流情况,根据两条道路上的车流量之比等于两方红绿灯的绿灯亮起持续时间之比,实时自动调整当前红绿灯的时间。若是一方双向道路无车,而另一方有车,无车道路方红绿灯的绿灯时间置为最小值,有车方绿灯时间根据车数确定。该文搭建了基于Arduino控制的智能交通平台模型,来模拟演示红绿灯具体的调整方案,利用到Arduino的中断、串口通信机制,采用车辆计数控制与红绿灯控制分离的方式,设置按钮中断来进行智能模式与备用模式的切换。
This design uses metal sensor as the vehicle sensor to be placed under the road surface to monitor the traffic flow. According to the ratio of the traffic flow on the two roads, it is equal to the ratio of the green light duration of the two traffic lights, and the current traffic light time is automatically adjusted. If one of the two-way roads has no cars and the other has a car, the green time of the traffic lights on the car-free roads is set to a minimum, and the green time of the vehicles is determined according to the number of cars. This paper builds an intelligent traffic platform model based on Arduino control to simulate the specific adjustment scheme of traffic lights. It uses Arduino′s interrupt and serial communication mechanism, and uses vehicle counting control and traffic light control to separate and set button interrupt to intelligent mode. Switching of the standby mode.
