Gaze direction and driving behavior of drivers at level crossings

Abstract

Abstract: International level crossing statistics reveal that the majority of accidents at level crossings occur due to human error on the part of car drivers. Often, the rather unspecific description of “attentional deficits” is given as the cause of most accidents. In this study, driving data and eye-tracking data were collected during a standardized driving study. Using a research vehicle, the behavior of 24 participants was observed while approaching two level crossings (one with passive protection, the other with active light-signal protection). It turned out that on the last 300m of the approach towards level crossings, all of the drivers detected and fixated upon at least parts of the protection layout at both level crossings. Nevertheless, only one third of all participants subsequently derived the right reaction and checked the rails for an oncoming train. Two thirds of the participants did not direct their attention towards the rail tracks. With such deficient gaze behavior, visual detection of a potentially oncoming train is difficult. In addition to the maladaptive gaze patterns, inattentive drivers decelerated significantly less while approaching both level crossings than attentive drivers.
