This invention relates to a system to alert drivers and bicyclists of a pedestrian crossing in a crosswalk in nighttime or dark conditions. It uses road markings consisting of a fluorescent pigment installed on a pedestrian crossing. A sensor detects the presence of a pedestrian intending to cross at the crosswalk and then an ultraviolet light source, not visible to the pedestrian, is activated to irradiate the fluorescent road markings, which then emit visible light seen by the oncoming vehicle. The system communicates with a paired and identical alert system on the other side of the crosswalk to illuminate the road markings on both sides of the road and account for pedestrian crossing from either side.
