Portable traffic signals allow you to use fewer flaggers. One pair can be quickly and easily installed to control a single lane closure; four Pop-Ups can handle complex intersections even where there's no pre-existing infrastructure to support them. At 6 ft., the signal's footprint is the industry's smallest. Lightweight enough to be towed with a pickup and narrow enough to fit anywhere. The LD Pop-Up features the ATC controller with Maxtime software. Control units communicate via wireless encrypted radio.
