This report is the first in a series dealing with head movements as an indicator of attention distributions of drivers in traffic situations. In order to study head movements in driving special car mounted equipment was constructed. The apparatus registers drivers' head movements in three dimensions using three potentiometers as sensing unit. In a pilot study it was found that in urban road crossings the sum of maximum horizontal head movements to the left and to the right (head angle) seems to be a consistent and reliable measure of head movement activity. Head angle seems to differentiate well between crossings and to correlate negatively with vehicle speed. Suggestions for continued studies are made.(a)
