Eye movement and driving behaviour in curved section passages of an urban motorway

Abstract: This study focuses on driver eye movements and vehicle control behaviour, factors implicated in the human errors that are considered to be important factors that may cause traffic accidents. Some curved sections of urban motorways have a comparatively high frequency of accident occurrence. The authors attempted to link three factors, namely eye movement, roadway alignment, and driver speed and steering control. In order to analyse the factors that lead to human error, an in-car experiment was carried out on some routes with curved sections of the Tokyo Metropolitan Expressway. This study focuses on single-car collisions occurring primarily in free-flow regions. Using the results of the experiment, the authors were able to analyse the factors that produce human error in relation to motorway alignment, eye movement, and centrifugal acceleration in the curved sections. As a result, the authors proposed a model that evaluates the risk of curved sections in relation to the driver’s eye movement and driving behaviour
