Controls Work Vehicles Entering Roadways and Warns Motorists

SAWS provides a safer ingress and egress solution to address the dangers on construction haul roads and intersection crossings. The system detects approaching vehicles and notifies dangerous entry vehicles to stop or yield. It simultaneously warns the public of entering vehicles.

How SAWS Works

When a construction vehicle is detected, SAWS activates an LED regulatory edge-lit sign trailer, which then communicates via radio to activate an LED wig wag trailer. The edge-lit advanced warning sign on the main lanes warns motorists of trucks entering.
