A Wrong Way Ramp (WWR) detection system is described. The system is based on (i) in-ground magnetometer sensor grids which wirelessly communicate vehicle detection events to an access point; (ii) algorithms identifying wrong-way events with a high detection rate and low false alarm rate for a variety of vehicle and driver behaviors; (iii) video monitoring and notification; and (iv) Driver alerts. The system design, test issues and resolutions, and field results are presented.
