A wrong way vehicle detection system may include a warning station, a communications device and a controller to operate a forward facing movement sensor at the warning station to detect a wrong way vehicle on the roadway, and responsive to the detection of the wrong way vehicle on the roadway by the forward facing movement sensor, activate at least one flashing beacon and operate a rear facing movement sensor at the warning station to detect movement of the wrong way vehicle beyond the warning station. The controller may also, responsive to detection of the wrong way vehicle moving beyond the warning station, send a wrong way vehicle detection alert via the communications device. The system may further include a navigation server to receive the wrong way vehicle detection alert and send a wrong way driver warning to a mobile wireless communications device(s) within a geographic boundary of the warning station.
