For ATC Controller Products throughout Australia

Our Products

We manufactures a number of traffic signalling products for urban intersection control, motorway entrance traffic flow and lane use management. While all of our traffic signalling products are designed to be SCATS® compatible, many can be customised for specialist application use.


The ATSC4 Traffic Signal Controller is ATC's flagship product and is a high technology solution with a high degree of reliability that is SCATS® compatible and runs the VC5 SCATS protocol if coordinated by a SCATS® system or can run on its own in Flexilink Mode whereby the controller has a set of plans to run at given times of the day. Click here for more information.

Ramp Metering

Related to and based on the ATSC4 Traffic Signal Controller, is ATC's Ramp Metering Controller that controls 1 or 2 sets of signals on a ramp joining a high speed motoroway allowing 1 signal green at a time to minimise delays on the motoroway due to the joining vehicles being slower than the motorway vehicles. Learn more about Ramp Metering.

Lane Use

A Lane Use Controller is also available whereby a specialised ATSC4 controller is configured to drive special LED Lanterns, generally a green arrow or red cross to indicate if the lane is available to a motorist travelling in a given direction. The application for Lane Use systems include bridges, tunnels, narrow roads or other roads where some lanes can change direction during the course of a day to assist with peak hour traffic or accidents/emergencies. Learn more about the Lane Use Controller.

SID (System Interface Device)

For customers that have existing controllers or purchasing controllers that are notSCATS® compliant but wish to connect them to a new SCATS® system, ATC provide a System Interface Device (SID) product to convert SCATS® Adaptive coordination commands to a series of hardware force-and-hold signals that are interfaced to a foreign controller to control the time the foreign controller stays in a phase and then force it to move to a new phase in coordination with SCATS®. This preserves the investment in the existing Controller asset but provide fully adaptive traffic control on the road using SCATS®Learn more about the SID.

Cardbus Cards & Programmer

To program the configuration or "personality" of an intersection within a traffic signal controller, ATC manufacture a Cardbus Card and programmer to allow service personnel to install a newly configured personality at a new or existing intersection. Click here to learn more.

Legacy Alpha16 Controller

While the Alpha16 has been superceded by the ATSC4, spare parts are still available to those with the legacy controller. To request a quote for Alpha16 Parts, click here.
