Lighting Techniques and Methods for Some Essential Components of Road Infrastructure in Romania

Good quality lighting of streets, National Roads (DN) or highways is essential for road safety, personal safety and the urban or suburban environment. It also supports commercial and recreational activities at night, which can have a major impact on the economic growth of the area. The purpose of street lighting is not to direct light directly in front of cars, this is done by using their headlights. Instead, the adjacent areas are illuminated, hiding potential hazards from the side (street intersections or roadside). The scientific paper presents an original study and a personal opinion of the authors on the techno-economic and scientific acceptance of techniques and methods of lighting some essential components of road infrastructure in Romania. In this way interested readers can learn about the need for lighting of road infrastructure components, some theoretical considerations on the lighting of road infrastructure components, siting solutions for lighting systems of road infrastructure elements, risk areas involving street lighting, illumination of intersections of National Roads as well as between national roads and other intersecting public roads, illumination of railway level crossings, illumination of pedestrian crossings on National Roads, illumination of parking areas, illumination of road junctions, illumination of public transport stations, illumination of art elements (bridges, footbridges and overpasses) and illumination of toll stations. At the end of the paper, conclusions are drawn and presented on the research carried out by the authors.
