Abstract:

For many institutions, it is important to evaluate a given driving technique as safe or unsafebased on measurable vehicle movement parameters. The paper constitutes a part of studies aimed atestablishing a method of parameter-based evaluation of drivers in various road conditions, in otherwords, to create a so-called ‘driver profile’. The tests were carried out on a 650 km route, on fourvarying road types. Longitudinal and lateral acceleration values are used to evaluate the drivingstyle. An analysis is presented of the impact of the type and shape of road on acceleration values.The results demonstrate that the same driver, when driving the same vehicle on an expressway, aninter-urban road or in urban traffic, will move with various acceleration values. A detailed analysisof acceleration values and distributions was conducted. Interesting conclusions were drawn afterexcluding the so-called ‘smooth driving’ sections, by acceleration ranges of−0.5 to 0.5 m/s2from theanalysis. This allowed for the evaluation of the structure of other longitudinal and lateral accelerationvalues. After this modification, the distributions showed specificity for the given road type, therebyallowing the road type used by the vehicle’s driver to be recognized based solely on the distribution.
