Prototyping and Field Testing of a Demand-responsive Rumble Strip Mechanism

This project includes the design, prototyping and field testing of a Demand Responsive Rumble Strip (DRRS) mechanism, which becomes active (lowers) only when needed. This mechanism is to be installed on travel lanes upstream of locations with safety concerns. Making the rumble strips active only when needed prevents drivers from becoming accustomed to the effects of the rumble strips while minimizing the nose as compared to permanent rumble strips. Hence, drivers’ attention will be regained making them aware of the presence of pedestrians in the roadway. In addition, in the context of autonomous vehicles, the proposed mechanism provides redundancy so as to minimize the likelihood of a crash as a consequence of system failures and/or malfunction. In the context of connected vehicles, the proposed mechanism can be activated through communication with vehicles and pedestrians.
