Information Sources

The opportunity to provide an affordable urban TMC service in Australia is only possible through the combination of several advanced ITS (intelligent transport system) technologies. In particular Suna Traffic Channel uses the traffic light control systems (SCATS & STREAMS) and specialist traffic flow modelling technology developed by the Australian company Custom Traffic Pty Ltd.

Suna Traffic Channel data is generated by the information gathered at the sensors on the road networks on arterial roads and freeways. In Melbourne the base traffic data is from VicRoads and other sources.

The most important source of raw traffic flow data is derived from the loop sensor network embedded in the road pavement on the approach to signalised intersections. Virtually all urban (and many regional) signalised intersections are networked to central traffic light control systems in each state. By agreement with the respective road authorities to value-add this data, we are able to develop and drive near real-time link-by-link congestion models.

The output of a congestion model is only the start. Intelematics has entered into an exclusive agreement with ITIS, a European leader in TMC technology for the encoding and decoding of the Suna traffic channel service.
