ABSTRACT:
A traffic control device with folding legs which form a sawhorse type base when extended, and which fold for storage. The traffic control device has wheels which come into contact with the road surface when the frame of the traffic control device is lifted at one end. Attached to the traffic control device is a simulated flagman which has a head, a torso and an arm. The arm supports a two-sided traffic control sign. The sign is placed in a sign holder of the simulated flagman, and a motor turns the sign 180 degrees in either direction to expose one side or the other of the traffic control sign. The motor is controlled by a wireless remote transmitter and receiver. The device can be operated by a flagman, allowing the flagman to be situated in a position of safety from the traffic. One or a pair of these devices can replace one or two flagmen in controlling traffic.
