Intelematics, a subsidiary of the Royal Automobile Club of Victoria, has launched its SUNA service, which delivers real-time information about traffic and road conditions to portable navigation systems.
Adam Game, Chief Executive Officer, Intelematics said the SUNA service "provides deep urban arterial coverage rather than just focusing on inter-city freeway links such as services in Europe and will initially cover more than 75 per cent of Australia's urban population".
The system is designed to be purchased fro between $100 to $150 as a value-add on with nay new popular-branded GPS device and provides around-the-clock information on traffic delays and road incidents directly to the driver's GPS system, allowing motorists to avoid congested roads. By collecting raw traffic flow data from a loop sensor network embedded in the road pavement near intersections. Virtually all urban and many regional signalised intersections are networked to central traffic control systems where the data is aggregated.
The company then feeds the signal system data into its traffic model of the entire urban arterial road network. The traffic model produces estimated delay and travel time for each road segment across the network approximately every three minutes. This travel time data is merged with incident information and traffic messages created.
