LIGHTING OF INTERCHANGES

ALUMBRADO DE NUDOS

IN ROADS AND MOTORWAYS, THE MORE DANGEROUS LOCATIONS ARE THOSE WHERE THERE IS A PHYSICAL DISCONTINUITY OF THE ROAD, E.G., CROSSINGS, ACCESSES, INTERCHANGES AND IMPORTANT JUNCTIONS. THESE ZONES ARE PRIORITY ZONES AS REGARDS STREET LIGHTING. LIGHTING SYSTEMS FOR INTERCHANGES ARE: CONVENTIONAL LIGHTING SYSTEMS WITH MEDIUM-HEIGHT MASTS AND SYSTEMS WITH HIGH MASTS. THE LATTER REDUCE GLARE TO A MINIMUM AND DISPEL THE "TUNNEL" EFFECT DECREASING THE RISK OF COLLISIONS. DETAILS ARE GIVEN OF THE STAGES OF THE INSTALLATION OF A STREET LIGHTING SYSTEM FOR AN INTERCHANGE WHICH USES HIGH MASTS. THE PROJECT VARIABLES (LUMINANCE AND ILLUMINATION, UNIFORMITY AND OUTPUT COEFFICIENTS, AESTHETICS, GLARE), THE NUMBER, POSITION, HEIGHT AND ORIENTATION OF THE MASTS, THE SELECTION OF THE TYPE OF LAMP (HIGH- OR LOW-PRESSURE SODIUM VAPOUR, MERCURY), LANTERN OF PROJECTOR ARE DESCRIBED.
