The "field of safe travel" revisited: interpreting driving behaviour performance through a holistic approach

Papakostopoulos, Vassilis

The present paper proposes a conceptual framework for the driver's visual-spatial perceptual processes. Based on a theoretical analysis of driving proposed by Gibson and Crooks [(1938). A theoretical field-analysis of automobile-driving. The American Journal of Psychology, 51, 453-471. doi: 10.2307/1416145 ], the developed field of safe travel (FoST) framework suggests that at any moment the driver constructs a "field" by integrating two perceptual entities: (i) the possible available spatial fields for locomotion and (ii) the driver's mental image of ego-vehicle outer-line and motion dynamics. This framework is used to reinterpret in a unified way a number of disparate research findings reported in the literature concerning specific driving sub-tasks (e.g. lane keeping and car following). It is argued that the FoST framework may be used to predict drivers' behaviour in various traffic/situation environments based on their prioritisation between the above two perceptual entities. Implications of the proposed framework at a theoretical and practical level, in view of the future of driving with multiple levels of automation, are also discussed.
