Faster HD Traffic Signal Test Works - Better Updates
A recent test has proven that a new faster algorithm can deliver faster downloads to HD raio based traffic receivers making HD radio able to pull down the data feed 10 times faster than RDS/TMC based feeds to regular GPS units. The fatter pipe is the difference between getting generic announcements "Accident" and the potential for more relevant information - "Traffic Accident Right Lane near Exit #3". The advancement also leaves space for finer slices on road traffic conditions, giving a more detailed look at what parts of the road are jammed and what is not. It will also allow for traffic prediction capability, something that is available from major suppliers, but has yet to work its way into a mainstay GPS unit.
The recent test was conducted with a new specially equipped BMW, in Philly, where it was able to download signals quickly and completely offering a fast download speed and complete picture of the traffic situation. The new digital format is 10 times faster than RDS/TMC - FM based signals, while the older digital format is only 4 times faster. Look for availability later this year.
