WRONG WAY INDICATION BEACON AND RELATED METHODS
First Claim
1. A wrong way vehicle detection system comprising:
- a warning station positioned along a roadway and comprisinga wrong way indication sign facing away from a direction of oncoming traffic on the roadway,at least one flashing beacon adjacent the wrong way indication sign,a forward facing movement sensor adjacent the wrong way indication sign and facing away from the direction of oncoming traffic on the roadway, anda rear facing movement sensor adjacent the wrong way indication sign;
a communications device;
a controller configured tooperate the forward facing movement sensor to detect a wrong way vehicle on the roadway,responsive to the detection of the wrong way vehicle on the roadway by the forward facing movement sensor, activate the at least one flashing beacon and operate the rear facing movement sensor to detect movement of the wrong way vehicle beyond the warning station, andresponsive to detection of the wrong way vehicle moving beyond the warning station, send a wrong way vehicle detection alert via the communications device; and
a navigation server configured to receive the wrong way vehicle detection alert and send a wrong way driver warning to at least one mobile wireless communications device within a geographic boundary of the warning station.

Abstract
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.

12. A wrong way vehicle detection method for a warning station positioned along a roadway, the warning station comprising a wrong way indication sign facing away from a direction of oncoming traffic on the roadway, at least one flashing beacon adjacent the wrong way indication sign, a forward facing movement sensor adjacent the wrong way indication sign and facing away from the direction of oncoming traffic on the roadway, and a rear facing movement sensor adjacent the wrong way indication sign, the method comprising:
-
operating the forward facing movement sensor to detect a wrong way vehicle on the roadway; responsive to the detection of the wrong way vehicle on the roadway by the forward facing movement sensor, activating the at least one flashing beacon and operating the rear facing movement sensor to detect movement of the wrong way vehicle beyond the warning station using the controller; responsive to detection of the wrong way vehicle moving beyond the warning station, sending a wrong way vehicle detection alert via the communications device using the controller; and at a navigation server, receiving the wrong way vehicle detection alert and sending a wrong way driver warning to at least one mobile wireless communications device within a geographic boundary of the warning station. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
