The objectives of TeleFOT 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 services and functions relate to cooperative driving like providing information on incidents ahead, traffic and road conditions and the like. Knowing that similar types of activities are underway elsewhere like in USA and Korea, selected members of the TeleFOT consortium are seeking cooperation outside Europe. Cooperation countries are USA and Korea. Especially USA is experienced in Field Operational Tests and Korea in innovative communication technologies and services, whereas some European countries are advanced in providing services for travellers. Consequently, it was found beneficial for both European and overseas projects to get together, discuss essential methodological issues, exchange views on testing, services and business models associated with the use aftermarket devices in vehicles. Also the objective is to find a common methodological basis in order improve comparability of tests in different regions worldwide. The main thing these countries share is the use of nomadic and aftermarket devices as one platform or interface for informing drivers of events and conditions having significance to their travel. All projects assume that cooperative driving technologies will make an essential part of the future driver assistance functions and services. All cooperation partners find it important to know the impacts of these systems on travellers' behaviour and choices and the role of aftermarket devices in this. In addition to the proposed joint activity, the proposers find this an opportunity for creating basis for future R&D activities with best players around.
