Intelematics will now use thousands of probe vehicles across Australia to monitor traffic flow in a major enhancement of its SUNA traffic service.Called SUNA Phase 2, this new service features a range of improved technologies, including the integration of speed data collected from thousands of vehicles including taxis, road service vehicles, courier vans, coaches and GPS-equipped private vehicles. This will deliver more detailed road coverage and higher precision than its current traffic model.
Intelematics Australia’s CEO, Adam Game said that the service upgrade will go live in the third quarter of 2010 at no additional cost to existing SUNA Traffic Channel customers.
“SUNA Phase 2 will deliver tangible improvements to the accuracy and level of coverage currently provided to motorists. Drivers will have greater understanding and control of the road conditions around them, delivering a safer and more enjoyable motoring experience,” said Game.
“SUNA Traffic Channel provides a real-time traffic service that enhances the driving experience of Australian motorists by helping them understand, anticipate and respond to changes in traffic flow and road conditions,” added Game.
The new fleet of probe vehicles will complement the technology already employed by Intelematics to monitor congestion levels, which leverages sensor infrastructure associated with traffic light control systems and freeway and toll-way management systems.
GPS probe vehicles, sometimes referred to as ‘floating vehicles’, measure their location, bearing and speed at regular intervals and then upload this information to servers using a cellular data connection. GPS data provides a highly accurate measure of travel times that provides reliable information even in dense urban road networks where less precise positioning techniques break down.
Fusing the data generated by the probe vehicles and the road sensors provides the opportunity to generate quality and coverage levels that cannot be achieved through a single technology. Integrating the data enables the automation of congestion monitoring across freeways lacking speed monitoring infrastructure and 24/7 congestion monitoring on less trafficked arterial roads even when floating vehicle data is sparse.
Intelematics Australia is currently conducting thorough testing of SUNA Phase 2 across Melbourne and Sydney.
