Samenvatting
Prior research has suggested that the use of daytime running lights (DRL) on operating vehicles can reduce the frequency and severity of collisions. The objective of the effort reported here was to obtain data on perceptual effects of DRL intensity, lamp area, colour, number of lamps and lamp /background contrast in the above areas. Three experiments were performed to investigate human performance as functions of these design parameters in tasks involving peripheral vehicle detection, turn signal detection and rearview mirror discomfort glare produced by DRL.
