Identification of patterns of driver speeding behaviour and safety margins from tangent to curve, 2018
A paper titled “Identification of patterns of driver speeding behaviour and safety margins from tangent to curve” authored by Eleonora Papadimitriou, Stergios Mavromatis, Dimosthenis Pavlou and George Yannis is now published in Advances in Transportation Studies. This paper presents a novel definition of drivers’ safety margins reflected in speed profiles on a tangent to curved road design. These safety margins are based on a vehicle dynamics model, which is implemented to assess the speed variation at impending skid conditions from tangent to curve on the basis of several parameters. Data from a driving simulator experiment are used to test the proposed methodology, explore driver’s speed profiles and the parameters affecting drivers’ safety margins. The results suggest that drivers’ safety margins towards the examined curve are considerable, with the majority of the drivers using less than 55% of the available vehicle engine power.
