Navigation Technologies, a provider of digital maps for vehicle navigation, Internet/wireless, government and business solutions, and TANN, a provider of real time traffic and travel information, are collaborating on a four-city trial of Navigation Technologies' real-time traffic data solution for North America. The trial is currently underway in Chicago, Los Angeles, New York and Detroit. Navigation Technologies has developed a traffic data solution designed to aggregate the data of multiple leading traffic data providers, like TANN, to provide the highest quality real-time traffic information. The information is packaged for delivery to vehicles and wireless handheld devices to help drivers in North America make smart routing decisions. According to Navigation Technologies, the solution is designed to provide detailed traffic information aggregated specifically for navigation applications. It utilizes multiple sources and types of information from incident (accidents, stalled vehicles, etc.) and flow (speed and movement of traffic) to weather and events. The information is merged with NAVTECH(R) map data through a data integration process for delivery to an in-vehicle navigation system, PDA or mobile phone through a wireless signal. Navigation Technologies says its traffic data solution employs an inclusive, flexible architecture that is scalable to multiple data providers and markets. TANN's traffic incident and flow data are key enablers of Navigation Technologies' four-city traffic trial. TANN is a vertically integrated traveler information news network, providing its partners with end-to-end digital technology communications solutions designed to promote the most efficient use of highways, streets and transit systems. TANN says its offers "in-depth, user-friendly and personally relevant traveler information news, enabling commuters to make informed traveling decisions." Navigation Technologies first demonstrated a North American traffic data solution in October 2002 at the 9th World Congress on Intelligent Transportation Systems (ITS), the global conference and exhibition on transportation technology.
