A remote controlled mobile traffic control system which can be used in the place of a human flag person. A mobile platform with an adjustable traffic control indicator thereon is controlled by a remote control. The operator can move the platform and change the indication of the traffic control apparatus from a safe distance. The apparatus permits “flagging” of traffic in a moving traffic control zone arrangement, and operational safety is maximized. A traffic barrier arm is movable between deployed and retracted positions obstructing the path of oncoming traffic, for example by a remote controlled actuator or by remote controlled turning of the platform. A remote alarm unit accompanies to the work crew to alarm them of traffic entering the work zone without authorization or at unsafe speed. The apparatus can travel with a moving or changing work zone, either by human remote control or autonomous “follow me” functionality.
