With the opening of Sydney and Brisbane services last week, SUNA now provides real-time traffic coverage across more than 75 per cent of Australia’s urban population. The service was initially launched in Melbourne last year.
“Whilst there is no magic solution to everyday congestion, SUNA can help motorists identify when delays are unusual or severe”, said Adam Game, Chief Executive Officer at Intelematics Australia. “In Sydney alone there are typically more than 200 traffic warnings about congestion and incidents every peak hour period”, he added.
Unique to SUNA is its ability to identify traffic congestion levels using data derived from traffic light control systems. Indeed, SUNA’s most important source of raw traffic flow data is derived from the loop sensor network embedded in the road pavement on the approach to signalized intersections. In Australia virtually all urban - and many regional - signalized intersections are networked to central traffic light control systems in each state.
SUNA also supplements the sensor-based data with information from probe vehicles deployed in known congested areas as well as live observation of road conditions by trained experts. The combined information is then broadcast in an encoded digital format via the FM frequency directly to compatible navigation devices.
PND manufacturers both sell SUNA as a bundle (Mio 370, TomTom XL Traffic, and TomTom GO 720 Traffic) and as a standalone receiver with lifetime subscription. For example it cost around USD $129 for a TomTom Traffic receiver.
