The original concept for the Vision in Vehicle series of international conferences was born from discussions within the Applied Vision Association which led eventually to the first conference being held in 1985. Ten years of progress later and this volume presents the selected and edited proceedings of the Sixth International Conference on Vision in Vehicles (VIV6) which was held at the University of Derby, 13-16 September 1995. The meeting was organised in association with the Applied Vision Association and the Ergonomics Society. The conference is unique in the eclectic mix of disciplines which are attracted to the meetings and this enables research inssues to be considered in very broad contexts. Chapter headings and selected papers: Preface. Driver's Visual Search Behaviour. Modelling changes in eye fixation patterns while driving (A. Liu et al.). Visual Inputs to Vehicle Steering.
