Despite continuous investment in road and vehicle safety, as well as improvements in technology standards, the total amount of road traffic accidents has been increasing over the last decades. Consequently, identifying ways of effectively reducing the frequency and severity of traffic accidents is of utmost importance. Going beyond existing research, we developed a comprehensive in-vehicle decision support systems, which provides accident hotspot warnings to drivers based on location analytics applied to a Swiss historical accident dataset, composed of over 266,000 accidents. The system was tested in a country-wide field test of 57 professional TCS drivers, with over 170,000km driven during a four-week period. Ultimately, we demonstrate that in-vehicle warnings of accident hotspots have a significant improvement on driver behaviour over time.
