Rugged Terrain No Problem for New Warning SignAbstract:
When highway maintenance or repair crews are on the job, they set signs up on the shoulder or slope at the side of the road, warning motorists of the work zone ahead. By alerting motorists to the change in travel conditions, the signs improve safety for workers and drivers alike.
Unfortunately, it isn’t always easy to set up the signs. While major highways generally have wide, flat shoulders with plenty of room for signs, many roads have narrow shoulders or no shoulders at all. This is particularly common in mountainous States like Tennessee.
To overcome this problem, the Tennessee Department of Transportation (DOT) uses the portable all-terrain sign and stand, a device developed by the Montana Department of Highways and evaluated by Tennessee DOT for the Strategic Highway Research Program (SHRP). The device features adjustable legs that can be placed on any slope. Stakes driven through the legs secure the sign to the ground.
