Abstract

This paper reviews the measures commonly used in experiments to evaluate collision avoidance systems. The use of Closest Point of Approach, Time to Closest Point of Approach, and Manoeuvre Magnitude was criticized particularly for multi-ship encounters. However, the data do suggest that two measures, Entropy and the use of experienced judges to give rank scores of performance, seem to be good measures even in multi-ship encounters. The use of a composite measure is not experimentally evaluated in this paper, but it is suggested that if one were used, it would have to be very complicated. Mr Cook is with the Department of Applied Psychology at UWIST, Dr Crawshaw in the Department of Psychology at the University of Hull.
