Description TeleFOT project will assess the impacts of functions provided by aftermarket and nomadic devices in vehicles and raise wide awareness of their traffic safety potential. The objectives of the TeleFOT project are to assess the impacts of functions provided by aftermarket and nomadic devices in vehicles and raise wide awareness of their traffic safety potential. These devices can provide different types of driver support functions and almost nothing is known about their safety and other impacts yet. The market penetration of portable navigators and smart phones is exploding today. The timing for the project is ideal. The functions to be tested cover two broad areas: Functions promoting (i) safe driving and (ii) economic and fuel efficient driving. These are Speed information, Traffic information, Road weather information and “Green driving” support. The impacts are assessed on levels ranging from usability; behaviour and incidents; safety; Green Driving and efficiency; to the impacts on the transport system. Attention will be also paid to possible negative impacts, since especially smart phones are not originally designed for vehicle use and navigators may have problems in fixing and positioning in the cockpit. The project also aims at speeding up the penetration of systems able to "see" beyond drivers’ field of vision in conditions where good situation awareness is needed. TeleFOT provides opportunities to test the impacts of similar functions future cooperative systems will provide after their development challenges have been solved in the coming years. In fact, aftermarket and nomadic devices provide an alternative to some important cooperative driving and ADAS functions for many years ahead. The concept comprises of creating three European test communities: Northern, Central and Southern. About 3 000 drivers participate in the tests. The project has strong national support and no resources are needed for setting up the testing infrastructures. Business models are also studied. Owing to very different traffic behaviour and reactions to safety measures in Europe, it is necessary to have test communities spanning from south to north.
