New Device Gives Drivers an Audible Warning of Upcoming Work ZonesAbstract:
In an effort to promote safer conditions in work zones, the Kentucky Transportation Center, in conjunction with the State of Kentucky and the Federal Highway Administration (FHWA), sponsored a project to demonstrate the use of the portable rumble strip at maintenance work zones across the State.
Developed by the Strategic Highway Research Program (SHRP), the portable rumble strip is placed across the road about 100 m (250 ft) in advance of the work zone. The device causes a vibration in the steering wheel and a rumble as vehicles pass over it, warning drivers that conditions on the road will soon become dangerous. The portable rumble strip is best suited for low-speed roads that carry few heavy trucks.
