Coded Rumble Strips to Enhance Reliability of Autonomous Vehicles

Road strips are used worldwide to alert drivers to changing road conditions and potential danger. These markers are currently passive and work by causing vehicle to vibrate, alerting drivers to pay attention to the road and road signs. In this work, we propose encoding the markers so that a message can be exchanged to help drivers and enhance autonomous vehicle performance. The instants vibrations occur can carry information that can be used by the vehicle. This information can be a warning message or information about the location. The proposed solution can be used by autonomous vehicles or ordinary vehicles equipped with motion sensing capabilities. Utilizing motion gyroscopic sensors, we illustrate how a message can be transferred and decoded from these markers.
