All of Rhode Island's limited access highways were targeted for improved signage and pavement markings to clearly distinguish exit ramps from entrance ramps and prevent confusion. At the two dozen high-risk areas, most in the Providence metropolitan area, new detection systems sense if a driver has entered a highway off-ramp, and activate a series of flashing signs. It will also notify the Rhode Island State Police that someone is driving the wrong way on the road, take a picture of the vehicle, and display a message on our overhead signs to warn drivers heading in the opposite direction.
Our plan is modeled on a similar project in San Antonio, Texas, where 29 flashing signs were installed along a major highway. Within a year, there was a 30 percent reduction in wrong-way driving incidents.
