Traffic Feeds via HD Radio Signal
By now, you are probably aware that some GPS devices can receive traffic feeds over the FM bandwidth (TMC Traffic) that are translated into visual representations of traffic situations, including incident reporting and traffic flow situations. At CES 2007, NAVTEQ is demonstrating the transmission of traffic feeds over HD radio waves, which just like the audio component offers a significant increase in bandwidth. This bandwidth increase will aloe more information to be sent which in turn can be changed into more personalized information for you and your GPS. Traffic coverage is set to increase and according to one report NAVTEQ is looking at using GPS equipped fleet vehicles (like Inrix does) to get more coverage than just roads equipped with sensors. With better coverage comes better information that is available, but the HD bandwidth increase should allows for more types of data display and more customized information.
