Abstract

A gender and age balanced sample of subjects viewed video footage which necessitated the judgment of the acceptability of gaps between two obstacles, as well as time-to-coincidence (TTC) estimates in relation to a stationary vehicle. Approach time was held constant while approach speed, gap size, and period of occlusion (for TTC) were systematically varied. Judgment accuracy was compared for footage obtained with a visible wavelength camera in darkness with the images from an infra-red thermal camera. Results indicated that approach speed, gap size, period of occlusion, and type of image affected judgment accuracy.
