Abstract
Systems, devices, and methods are disclosed in which one or more light sources, a detector, a processor and a controller are configured such that light from the one or more light sources improves the ability of a human or automated motor vehicle driver to identify and avoid pedestrians. The one or more light sources may provide spot illumination to moving objects or pedestrians on a road surface, with the spot illumination following the moving object or pedestrians along the portion of the road surface. The one or more light sources may project images on the ground or on other surfaces. The light source may be carried by a pedestrian or on personal transport used by a pedestrian. The light sources may be stationary and provide lighting for a pedestrian street crossing.
