The Driveway Assistance Device (DAD) has been designed to control driveways located within a one-lane temporary work zone. The system increases safety for both the motorist and the worker, while maximizing traffic flow through the work zone.
The DAD is a self-contained cart with a small footprint, which allows for easy maneuverability during deployment. The card features a battery bank with on-board 110-volt charger and an optional outrigger and solar charging system. Each signal is equipped with one 12″ solid red indication and two flashing red arrows, which alert the motorist that one way access is permitted in the direction of the flashing arrow.
HOW IT WORKS: The Driveway Assistance Device will display a flashing red arrow in the direction of the traffic traveling with the work zone. The motorist may proceed in the direction of the flashing arrow, yielding to the traffic traveling within the work zone. A solid red indication is displayed when it is not safe for the motorist to enter the work zone. Each DAD is linked to a portable traffic signal system controlling the work zone traffic. Communication between the system and the DAD is accomplished wirelessly.
Information signs are easy to affix to the signal mast
Engineered with recognizable signals to boost adherence
