The device is called an intrusion alarm and it warns workers via an earsplitting siren that a vehicle has entered the work zone, giving workers extra seconds to get out of the way. This article describes the technology behind the perimeter-marking device. A list of manufacturers is provided. The device was developed under the Strategic Highway Research Program.
