DAD

The Driveway Assistance Device (DAD) solves a longstanding work zone dilemma: How to control residential driveways that fall within a one-lane bidirectional workzone.

Since 2011, Horizon Signal has worked exclusively with various state Departments of Transportation to develop the DAD as an effective method for controlling driveway traffic. Each DAD is equipped with two flashing arrows to inform the motorists as to the direction traffic is flowing through the work zone. Drivers may enter the queue in the direction of the flashing arrow, thus reducing the likelihood of wrong-way driving within the lane closure.

As part of the signal system network, each DAD has full conflict monitoring capabilities. The DADs also have the capability to be activated and deactivated sequentially in order to maximize safety within the signal setup.
