NAVTEQ, a leading global provider of digital maps for vehicle navigation and location-based solutions, and DaimlerChrysler Research and Technology North America, Inc.
will be demonstrating, at the 12th Annual World Congress on Intelligent Transport Systems (ITS)
taking place November 6 - 10 in San Francisco, CA, a new technology prototype that
showcases wireless delivery of digital map data from wireless hot spots to
in-vehicle navigation systems. This technology will be showcased in a variety of locations at ITS including the NAVTEQ booth (#901) and in special NAVTEQ and DaimlerChrysler research
prototype vehicles.
NAVTEQ and DC RTNA are conducting this joint demonstration to focus on advancing
the quality of drivers" overall experience with their navigation system. The dynamic
nature of the road network makes the ability to quickly and accurately update the map
data powering a navigation system a true competitive differentiator for car companies
and location-based solution providers. The wireless map update technology is a significant
step in making it possible for drivers to receive updated map data while in route, utilizing their existing navigation systems.
Currently, in-vehicle navigation systems use CDs, DVDs or hard disk drives to store map data.
Due to the complexity and cost of the updating process, most automobile manufacturers release
updated maps on CD or DVD media only on a semiannual or an annual basis, creating a need for a faster, more frequent updating process. This research prototype illustrates how, through the use of DSRC (Dedicated Short Range Communication) technology, wireless map updates would allow drivers to drive by a designated
DSRC road side access point and download updates to their DSRC enabled navigation system. The server-based wireless delivery technology uses the commercial service channel of DSRC to transmit information at up
to 27 megabytes per second over a distance of up to 1000 meters. This system which operates in
real time is able to determine what new pre-processed map data the specific vehicle"s
navigation system needs and then prompts the driver to update their map.
Vehicle Infrastructure Integration is the wireless communication of safety, mobility and
commercial information among vehicles and the transportation infrastructure.
At the 12th Annual ITS World Congress, NAVTEQ is also collaborating with BMW, Motorola and Volkswagen of America, Inc. to demonstrate how VII technology,
and NAVTEQ’s dynamic data processing capabilities, can enhance driver experience and safety.
