SMART PHOTONIC GUIDANCE SYSTEM FOR ROAD SAFETY

Abstract

Despite therapid and continuous progress in the constructionofvehicles and accompanying improving road infrastructure,the road safety issue remains very serious. Especially, it concerns intersections and road junctions where nearly 30% of road accidents take place. The paper is focused on a newintelligent path displaying support system to be installed on intersections of complex geometry combined with multiphase traffic lights. It consists ofoptical projectionof two different horizontal signs,i.e. strips designating lanes for the green-light directions and perpendicular blocking lines for the red-light directions.
