According to the 2006 annual report of Trafficmaster, the parent company of Teletrac, Teletrac was monitoring 65,000 vehicles in the United States at the end of 2006. Therefore this agreement will offer Navteq’s subsidiary Traffic.com a robust set of additional floating data to further improve its real-time traffic information. Nevertheless, key competitor INRIX is already gathering “real time GPS probe data from more than 650,000 commercial vehicles across the U.S” said the company early September.
The “Real-Time Traffic Flow Ground Truth Testing Methodology Validation and Accuracy Measurement” study, published one year ago by Frost & Sullivan, was positioning INRIX as a leader in this field thanks to its GPS probe data. “Inrix's Smart Dust Network provides a major advantage,” said Veerender Kaul, Program Manager at Frost & Sullivan. “Instead of primarily relying on static DOT and radar sensor networks, Inrix is uniquely aggregating real-time data from over 625,000 GPS-enabled commercial vehicles and combining it with data from multiple private and public sources. Inrix's approach provides a scalable model enabling wide-spread road segment coverage of real-time speeds across the U.S.”.
