Abstract
Laboratory measurements were carried out to determine the detection potential of 25 normal observers engaged in an automobile headlight research programme. An exposure duration was selected to represent search and detection functions of night driving tasks. Target sizes and luminance ranges were chosen to encompass visibility conditions prevailing in automobile night driving. An analytical expression was then derived to yield threshold luminance increments required by normal observers as a function of target size and background luminance.
