2 An Exploratory Investigation of the Stochastic Nature of the Drivers' Eye Movements and Their Relationship to the Roadway Geometry

Since it has been estimated (Hartman, 1970), that a driver acquires over 90% of his information visually, an understanding of drivers' visual information acquisition patterns and cues would be not only desirable, but essential to an understanding of the input side of the driving process. If visual driving cues could be identified, they could be explicitly considered both in the formulation of driving models and in the design of the roadway environment. This could have a dual benefit of improving the quality of both.
