Abstract: Methods and systems are described for providing improved detection of a motor vehicle traveling against a designated direction of travel in a roadway. Multiple signals among various system constituents are checked against each other to ensure the lack of a false wrong way indication otherwise possible by use of a single detector. An alert is provided to the wrong way motor vehicle operator and other vehicle operators in the vicinity of detection. A long-range or cellular communication may be broadcast to further provide an alert of a wrong way event and to dispatch emergency personnel to the vicinity.
