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 earliest role as an exclusive distributor for Automatic Signal Company in Illinois, Indiana, and Wisconsin, TCC grew alongside the Midwest’s expanding transportation needs. Today, with headquarters, warehouse, and Illinois regional sales operations in Woodridge, Traffic Control Corporation supports state and local agencies, contractors, and consultants across eleven states.

Certification length depends on the specific course, agency requirement, manufacturer program, or equipment standard involved. Many traffic control credentials require periodic renewal, refresher training, or annual testing documentation, especially for safety-related equipment such as conflict monitors or MMUs. Traffic Control Corporation can help agencies understand available training options, documentation needs, and appropriate renewal planning.
