- The study presents findings regarding drivers' patterns of use, attitude towards, and reported effects of access tomature nomadic navigation support systems. Three different systems were tested by 582 drivers in four-field operationaltests for a period of six months. A majority of the participants used the support system for trips where the route/destination was unfamiliar but there were also other use scenarios. The main benefits entailed convenience andcomfort. Reported effects involved increased possibilities to choose the route according to preferences; a decrease inthe time it took to reach destinations and in the distance covered to reach the destination. One in four reported adecrease in fuel consumption attributed an increased compliance with speed limits and/or that driving around andsearching for the correct route to reach the desired destination could be avoided. A majority reported ‘no change’regarding the number of journeys made by car. Reported effects (whether increases or decreases) were howeversmaller than expected before the trial.

Journal article (peer-reviewed)abstract
- ICT-mediated traffic information has been argued to contribute to a more sustainable transport system through affecting drivers. Nevertheless, long-term effects of travellers having access to nomadic in-vehicle systems for traveller information are not well known. This study presents the results from a multi-national large-scale field operational test (FOT). The results show that the users in general were positive to the tested systems and that there were several effects on their driving behaviour but in many cases the effects were limited. Moreover the effects varied between system types. Positive effects were related to comfort, as well as individual and system efficiency. One could also notice that perceived effects were not as high as the participants had expected, leading to some disappointment. Most of the times this was due to the tested systems functioning in a less than optimal way.
