Traffic Control Corporation was founded in 1946 by Joseph Lizzadro, Sr. and Edward R. Hansen at 134 North LaSalle Street in Chicago, Illinois. From its early role as an exclusive distributor for Automatic Signal Company in Illinois, Indiana, and Wisconsin, the company grew into a leading Midwest distributor of traffic signal equipment and ITS solutions.

Its vision remains practical and service-focused: help transportation professionals apply dependable technology, solve field problems, and keep roadway systems moving safely.
A dynamic message sign is an electronic traffic sign that displays changeable messages for drivers. Agencies use these signs to communicate crashes, congestion, travel times, work zones, closures, detours, weather warnings, and public safety alerts. Unlike static signs, Dynamic Message Signs (DMS) can be updated remotely or locally so roadway information stays current as conditions change.
