Abstract
The TeleFOT EU/FP7 project aims at assessing the impacts of telematic functions provided by nomadic and aftermarket devices, such as navigation support and speed limit information, on traffic safety, user mobility and environment. As much as 3000 test users will form the test communities of Finland, Sweden, UK, Italy, Spain and Greece. For the collection and analysisof the data a data collection system is needed, which allows collecting input from various heterogeneous sources and extracting relevant data for all analysts. This paper will describe the issues which have to be taken into account when developing the data collection system, gathering information from a heterogeneous amount of devices and services.
