Abstract

A portable signal for traffic control at intersections, school crossings, traffic accidents, road repairs, and road construction. In the first aspect of the invention, the signal is suspended from an overhead cable which supports an existing traffic signal. The signal is formed by attaching one or more detachable light panels to the sides of a control module. Each light panel is comprised of a rectangular housing and a vertical array of red, amber and green lights mounted in the housing. The control module is a generally rectangular unit comprised of a housing and controls, timing circuits and a power supply mounted in the housing. The timing circuits are conventional and control the 'on' and 'off' periods of the red, amber and green lights. A remotely controlled power hoist is attached to the top of the control module for raising and lowering the traffic signal. In a second aspect of the invention, the traffic signal is supported on a vertical post which rests on a road surface. In a third aspect of the invention the traffic signal is supported on an open bed of a pick-up truck.
