Abstract
This report summarises the total research effort, with emphasis on the final phase which covered a series of experiments relating driver and pedestrian gap-acceptance to illumination level, uniformity ratio, vehicle lighting and vehicle speed. The major conclusions of the research are that drivers' responses to a roadway obstacle almost always improved in the presence of increased illumination, left turning drivers and pedestrians will utilise available lighting to maximise safety, and gap-acceptance performance variability increases with illumination. Parking lights resulted in an overestimate of separation distance in the intersection crossing situation. (A)
