Traffic Control Centre

Transport SA’s Traffic Control Centre (TCC) located at Norwood forms the central hub of a comprehensive and advanced data gathering system which manages Adelaide’s traffic flow.

Many people take the operation of traffic lights for granted. The state-of-the-art facility and the equipment that is required to keep the traffic flowing in Adelaide amaze first-time visitors to the Traffic Control Centre (TCC) at Norwood.

In fact, the Traffic Control Centre somewhat resembles the bridge of the Starship Enterprise or even NASA Ground Control with its wall of television monitors, large workstations, communication equipment, and highly sophisticated computer systems.

On a tour of the Traffic control Centre, visitors can

• view, in real time, computer generated images of any of the 580 traffic signal sites connected to the ACTS (Adelaide’s Coordinated Traffic Signal) system (you can even request the operator to dial up an intersection that is near your home or on your travel route)
