The invention relates to a principal-vibration wave expressway vehicle overspeed detection method with a location function. The principal-vibration wave expressway vehicle overspeed detection method includes fixing vibration wave detecting unit sensors in an expressway roadbed layer, amplifying signals and processing frequency spectrum by detecting vibration wave signals generated by vehicles passing the pavement on the expressway, providing vibration wave track information of same frequency characteristics to a data processor, starting cameras to take pictures of overspeed vehicles on the road segments when speed information given by the vibration wave track information of the same frequency characteristics is larger than the overspeed value. The principal-vibration wave expressway vehicle overspeed detection method has the advantages of long detection distance and capability of determining location of overspeed expressway vehicles by the technology method.
