Patterns of use, perceived benefits and reported effects of access to navigation support systems: an inter-European field operational test

The study presents findings regarding drivers’ patterns of use, attitude towards, and reported effects of access to mature nomadic navigation support systems. Three different systems were tested by 582 drivers in four-field operational tests 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 and comfort. Reported effects involved increased possibilities to choose the route according to preferences; a decrease in the time it took to reach destinations and in the distance covered to reach the destination. One in four reported a decrease in fuel consumption attributed an increased compliance with speed limits and/or that driving around and searching 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 however smaller than expected before the trial

Impacts on safety - results and implications: TeleFOT [Field Operational Tests of Aftermarket and Nomadic Devices in Vehicles]. D4.4.3 Vol 0.4

This deliverable presents the full and final analysis results in relation to the safety impact assessment. It then draws upon these results to discuss the impact that the functions provided by Nomadic Devices have upon safety. The deliverable is structured so as to present the key results for each Research Question (RQ) and Hypothesis within the main body of the report. These main results are then restructured on a function basis in order to assess the impact of each function upon; • Route Choice • Distance Travelled • Distraction • Speed • Lane positioning • Braking behaviour • Manual activity Further supporting analysis for each RQ is provided in Annex 1. Subsequently, an evaluation is made relating any impacts observed to consequences for safety. This evaluation is made using results that refer to singular functions; results from Field operational tests (FOT) that evaluated bundles of functions are included within the results sections for each Research Question but not included within the evaluation. This is since there are no current rigorous methods accepted within the research community for dealing with bundles of functions; this is being discussed and considered within the revision of the FESTA handbook
