Abstract
A haul road safety system that includes a flashing stop sign is positioned at the intersection in a standard position. A doppler radar is set up and mounted on a wig wag warning sign typically; however, it can be placed on another platform in any convenient location. When the radar detects a moving vehicle, it causes the sign's electronics to activate and the sign to illuminate and its warning lights to blink. The sign is programmed to warn of the existence of the intersection and the necessity to stop ahead. At the same time, a radio signal is sent from the radar/electronics module to the flashing stop sign at the intersection which immediately begins flashing.
