The E ect of Field of View and Surface Tex - ture on Driver Steering Performance

In the present study we investigated steering accuracy in terms of our ability to keep to the middle of a lane in a xed-base driving simulator. In particular, we studied the dependence of steering accuracy on the visibility o f diierent road sections, on the assumption that performance reeects the importance of diierent road sections in guiding steering. Other innuences on steering accuracy-including the presence of textural cues, in the form of a textured road surface, and the horizontal eld of view-were also investigated. We found that textural cues can improve accuracy in lateral lane control, presumably by providing strong optical ow, and that driving accuracy is little aected by increasing the horizontal eld of view from 40 to a full eld of 180 .
