Page 1 of 2 SUNA Traffic Channel - Australia's first Traffic Message Channel (TMC) road information service - is set to go live in Melbourne by Christmas, spreading to Sydney and Brisbane by the end of the first quarter of 2008. Adelaide and Perth will be added later that year. Register now to win a Canon EOS 500D Developed by RACV subsidiary Intelematics Australia, SUNA aggregates and processes data collected by the traffic light control system plus human observation and messages from probe vehicles to identify trouble spots. Other data sources include the tow truck allocation system, and highway ice and wind sensors. Warnings of events such as major sporting fixtures and street parades are inserted ahead of time. Data is broadcast piggybacked on conventional FM radio signals, and can be decoded by suitably equipped in-car navigation systems. "Virtually all the world's navigation brands" including Garmin, Medion, Navway, Neo and Siemens are compatible, according to Intelematics CEO Adam Game. Some low-end models advertised in Europe as being TMC-enabled are sold here without being described as such, he noted. The navigation hardware generally interprets the messages and displays appropriate symbols on the map, and issues a verbal warning of incidents on the selected route. Some models offer dynamic guidance, which routes around obstructions that are likely to cause a delay greater than a threshold value. "Basically, you use the navigation system the way you usually do... and you start getting warnings," said Game. "We think traffic [information] is the hook" that will promote the adoption of embedded navigation systems, he said. Currently, less than five percent of new Australian cars are purchased with navigation systems, compared with around 25 percent in Europe. Current Australian sales run at 600,000 accessory navigation systems, compared with around one million cars. It is possible that more navigation systems than cars may be sold during 2008, Game suggested. << First page < 1 2 Next page > Last page - Post your comment >>
