Project Turns GPS Phones Into Traffic Reporters

wfberg TomTom did it! (119 comments)

TomTom takes anonymized location information from mobile phone handsets in The Netherlands, and make traffic reports they call HD traffic.

The handsets are not (necessarily) equipped with GPS chips, but their location is triangulated by the GSM network itself. The mobile network (Vodafone NL) supplies the information to TomTom, who then process it into traffic reports.

They claim to cover 10 times more roadarea than conventional traffic detection that uses inductive loops embedded in the roads. (The conventional system is already quite extensive in The Netherlands, which is a small and densely populated country). I seem to recall TomTom also have some sort of patent.

Your Blu-ray player won't play future discs

wfberg wfberg writes  |  more than 6 years ago

wfberg (24378) writes "Having won the format war, Blu-ray Disc Association president Andy Parsons expressed his gratitude to early adopters saying 'it's normal for new technology to change and older hardware to become obsolete'. Apparently, BD 2.0 discs will not play on current hardware, and only the PS3 might be upgradeable to 2.0. The explanation for putting out an incomplete standard? "We should have waited another year to introduce Blu-ray to the public, but the format war changed the situation""
