The Mobile Millennium traffic data is based in part on the backbone technology of NAVTEQ Traffic, which provides nation-wide aggregated traffic data in the US from a variety of sources, now including real-time data from GPS-enabled mobile phones in vehicles traveling on the highways.
The pilot will operate over four to six months and up to 10,000 members of the public community can participate.
A particularly interesting element of this trial is that the protection of personal privacy was built into the very core of the reporting technology used in Mobile Millennium. From inception, researchers built safeguards into the system, such as stripping individual device identifiers from the transmitted traffic data, using banking-grade encryption techniques to protect the transmission of data, and drawing data only from targeted roadways where traffic information is needed. The system continuously filters information to remove data that can be tied to a particular phone, minimizing the amount of sensitive information ever created, transmitted or stored.
This trial is very interesting because it allows Nokia and NAVTEQ to test such system on a rather large scale and ultimately to use these technologies in commercial applications in the coming years.
