An electronic warning system with highly advanced sensing algorithms designed to provide advanced warning to personnel within mobile work zones when there is a threat of vehicle intrusions and consisting primarily of a sensor that includes electronically-scanned radar, high-precision differential GPS, accelerometers, gyroscopes, and magnetometers for position and orientation sensing, high-definition video, and several wireless interfaces used to monitor traffic in the area and to broadcast a warning when an intrusion is detected, a second sensor that includes a tracking device that is typically strapped to the hard hat with high-precision position sensing as well as wireless interfaces in order to receive warning signals from the other system sensor and to and determine whether it is in the path of the oncoming threat, and a vibrator motor and acoustic buzzer to alert the user that the threat is approaching and activates lights and sirens when a threat is detected
