The invention relates to the technical field of intelligent traffic, and provides an overspeed detection method and system based on vehicle positioning. The method comprises the following steps: collecting real-time positioning data of a target vehicle; downloading road track information and road speed limit information; constructing a vehicle driving space coordinate system; adding the road speed limit information as constraint information to the vehicle driving space coordinate system to obtain a vehicle overspeed driving comparison space; performing coordinate conversion on the real-time positioning data of the target vehicle, and synchronously inputting the real-time coordinate position into the vehicle driving space coordinate system; and if the real-time coordinate position is out of the vehicle overspeed driving comparison space, a vehicle overspeed driving prompt is sent out. The problems that in the prior art, vehicle overspeed detection is slow, and a driver is not reminded in time are solved, and the technical effects that overspeed detection is fast, the driver is reminded, and the vehicle driving safety is improved are achieved.

    本申请涉及智慧交通技术领域,提供一种基于车辆定位的超速检测方法和系统。所述方法包括:采集目标车辆的实时定位数据;下载道路轨迹信息和道路速限信息;构建车辆行驶空间坐标系;将所述道路速限信息作为约束信息添加至所述车辆行驶空间坐标系,得到车辆超速行驶比对空间;对所述目标车辆的实时定位数据进行坐标转换,将所述实时坐标位置同步输入至所述车辆行驶空间坐标系;若所述实时坐标位置处于所述车辆超速行驶比对空间之外,发出车辆超速行驶提醒。本申请解决了现有技术中车辆超速检验较慢,提醒驾驶人员不及时的问题,达到了快速检测超速并提醒驾驶人员,提高了车辆行驶安全性的技术效果。
