Abstract

The article reports on two analyses of driver behavior conducted separately, one carried out in Vienna (Austria) and the other in Tubingen (Germany). The data on which the analysis was based were in both cases subjective judgements of 40 behavior characteristics of drivers. In each case two observers accompanying the subject in his vehicle noted the degree in which these characteristics were evident on a nine-point rating scale. Differences between the Vienna investigation and the Tubingen study lay in the team of observers, the test route, the type of vehicle and the size of the samples. The programs for measuring similarities between factor matrices have only recently been developed. The comparison deals primarily with interpretation of the contents of the resulting factor loading matrix and additionally with the interpretation of the measures of similarity for each variable. The experiments are described only as far as is desirable for an understanding of the two basic matrices. The aim of the project was to determine components of driver behavior in terms of reliable, meaningful measures which allow generalization.
