The invention discloses an expressway vehicle speed limiting method which comprises the steps of: arranging ground radars on lane marking lines between expressway carriageways, relays are arranged along an expressway, wherein the relays communicate with the ground radars; respectively recording a first moment when the first vehicle passes through the first ground radar and a second moment when the first vehicle passes through the second ground radar; determining the speed of the first vehicle according to the set positions of the first radar and the second radar and the time interval of passing through the two ground radars; and if the speed of the first vehicle is overspeed, reminding the first vehicle to decelerate. The ground radars can record the position of the vehicle in real time and feed the position back to the relay, and then the time when the vehicle arrives at each ground radar is determined. Due to the fact that the ground radar is arranged along the lane marking, the speed of the vehicle can be accurately obtained, if the vehicle is overspeed, the vehicle is reminded to slow down, and the speed of the vehicle is limited. By adjusting the distance between the ground radars, the speed measurement of the vehicle at different moments can be realized.
本申请公开了一种高速公路车辆限速方法,所述方法包括:在高速公路行车道之间的车道标线上设置地面雷达,沿高速公路布设中继,中继与地面雷达通信;分别记录第一车辆经过第一地面雷达的第一时刻和第二地面雷达的第二时刻;根据第一雷达和第二雷达的设置位置和经过两个地面雷达的时刻间隔确定第一车辆的速度;如果第一车辆的速度超速,则提醒第一车辆进行减速。地面雷达可以实时记录车辆的位置,并反馈给中继后,确定车辆到达每个地面雷达的时刻。由于地面雷达是沿着车道标线设置,因此可实现对车辆速度的精确获取,如果车辆出现超速,则提醒车辆进行减速,实现对车速的限制。通过调整地面雷达之间的间距,可以实现对车辆不同时刻的速度测量。
