| description | The invention provides a road risk pre-estimation analysis method and an anti-collision warning device, and the method comprises the following steps: S1, selecting an operation lane according to needs, and setting the range of an anti-collision warning region and a warning speed threshold value; s2, setting a lane adjacent to the operation lane as an overspeed detection alarm area, and setting a speed limit threshold value; s3, taking the lane width direction as an X-direction coordinate of a radar scanning surface, and taking the early warning distance of the anti-collision warning area along the lane direction as a Y-direction coordinate of the radar scanning surface; s3, starting radar scanning and analyzing scanning data; and S4, giving an alarm for the data meeting the judgment condition. The device comprises an early warning machine and a portable alarm device communicated with the early warning machine. According to the invention, corresponding judgment conditions are set according to different road co |
