For approximately 10 years, part of the research effort of the TNO Institute for Perception has been devoted to the analysis and modeling of driving behavior. In this paper, some of the most relevant research issues in this area will be reviewed. First, an impression is given of some theoretical and experimental studies on course perception and vehicle guidance in preview. Second, two nearly developed methods for describing vehicle control as a supervisory task are discussed. The predictions made with these models were verified in a field experiment in which subjects drove under conditions with temporary occlusion of visual input at different speed levels. Subjects' self-chosen occlusion durations could very well be explained by both models. Suggestions are given of how the proposed methods can be applied to optimize roadway and vehicle characteristics.

For approximately 10 years, part of the research effort of the TNO Institute for Perception has been devoted to the analysis and modeling of driving behavior. In this paper, some of the most relevant research issues in this area will be reviewed. They all start from the basic view that the driver behaves as an information-processing system, looking for relevant input data in order to be able to process the course and speed of his own and other vehicles and, accordingly, to act in the right way. The issues to be discussed concern basic performance while the results of both offer elements in modeling driver behavior.
