Abstract

This report describes a series of target detection tasks carried out at night on highway 417 in south-east Ottawa. Their purpose was to collect data on seeing distances for a group of subjects of known visual characteristics using headlamps of known illumination characteristics. Details are given of the five male subjects, between the ages of 26 and 40, who took part in the experiment, the equipment used, the site and the procedure followed. Tests were done both with and without a glare car facing the subject. All tests were carried out with the subject's car headlights on low beam. The subject's headlights were left on at all time so that he would be adapted to the luminance level they provided. An analysis of the results of these tests appear in report LTR-ST.599, entitled "detectability distances in some automobile headlight experiments, IRRD abstract no. 215263.
