ROSSLYN, Va.—Today, the National Electrical Manufacturers Association (NEMA) published NEMA TS 5-2017 Portable Traffic Signal Systems (PTSS) Standard. This new standard covers traffic signaling equipment used to enable and expedite the safe movement of vehicle traffic in work zones during roadway construction, such as single-lane road closures during emergencies and planned events.

According to Scott Heydt, Director of Marketing at Horizon Signal Technologies, Inc., and Chair of NEMA's 03TS Portable Traffic Signal Technical Committee, "NEMA TS 5 provides the traffic control industry with a much-needed standard for portable traffic signals, which differ significantly from permanent traffic signal installations, and accurately reflects the latest technologies being used in the industry."

NEMA TS 5-2017 is available for $138 in hard copy or as an electronic download on the NEMA website.


The National Electrical Manufacturers Association (NEMA) represents nearly 325 electrical equipment and medical imaging manufacturers that make safe, reliable, and efficient products and systems. Our combined industries account for 370,000 American jobs in more than 6,100 facilities covering every state.
