摘要：AbstractThe overall objectives of the TeleFOT project are to evaluate the impact of different functions provided by nomadic and after market devices (ND) on four impact areas: efficiency, environment, mobility and safety. The fifth area to be investigated is user uptake. The paper presents preliminary results from one of 13 field operational tests (FOTs), the Swedish L-FOT2 focusing on user uptake. One device and three functions were tested: a Green Driving Support System (GD), a Navigation Support System (NAV) and a Traffic Information Service (TI). Preliminary results indicate the importance of addressing the relative rather than the absolute benefits of a function, i.e. the benefits relative other functions offered by other channels/devices and, further, that the specific characteristics and contents of a function need to be analysed in depth order to understand user uptake.
