摘要: 针对当前大城市中心道路的交通拥堵问题,基于北斗卫星定位系统提供的车辆位置信息,设计并模拟实现了基于北斗的智能路标系统。该系统利用车辆中北斗定位终端提供的位置信息与道路参数作为变量,基于车道占有率建立了道路的实时路况模型,并通过路标的LED灯光颜色变换引导车流,最后,基于PC端与单片机的串口通信模拟了系统的运行流程。系统有效实施具有一定的实用价值。Abstract: Based on the vehicle location information provided by the BeiDou Navigation Satellite System, the intelligent road marking system based on the BDS is designed and simulated to solve the traffic congestion in the central city road. The system uses the position information and road parameters provided by the BeiDou positioning terminal in the vehicle as variables, establishes a realtime traffic model of the road based on the lane occupancy, and guides the traffic flow through the LED color change of the signpost. Finally, based on PC and the serial communication of singlechip simulates the running flow of the system. The effective implementation of the system has a certain practical value.
