3 3 Standardisering CIE ISO Internationalt CEN Europeisk nivå TC 169 WG9 NS Standard Norge NLK - Norsk Lysteknisk komité Fordrer internasjonalt samarbeid

4 4 CIE INTERNATIONAL COMMISSION ON ILLUMINATION Hovedkontor i Wien

5 5 Arbeidet Reportership v/ Eirik Bjelland i flere år Ønske om en egen Technical Report (TR) for adaptiv belysning Leon, Spania, møte sept 25 Vedtak om oppdatering av CIE 115 Pentti Hautala formann, Eirik Bjelland sekretær

6 6 Arbeidet Kommiteen består av mer enn 2 eksperter God geografisk spredning Har hatt møter i Europa, USA og Kina Axel Stockmar, Tyskland, har bidratt med arbeider Måling av refleksjon fra snø, Narvik

8 8 Adaptive Road Lighting Adaptive road lighting is defined as lighting provided where and when it is needed dependent on different variable conditions, such as speed, traffic volume and/or composition, ambient luminances, weather etc. NOTE (CIE 115:2X): Changes of the average lighting level should not affect the other quality criteria more than prescribed in the system of lighting classes.

9 9 Lighting Classes in CIE 115:2X There are three different sets of lighting classes in CIE publication 115:2X from which appropriate lighting quality criteria / requirements can be selected: M Lighting classes for motorized traffic C Lighting classes for conflict areas P Lighting classes for pedestrian and low speed traffic areas

10 Selection of Lighting Situation, Influencing Parameters in general Speed (composition of users in the same relevant area) Geometry (separation of carriageways, type of junctions, intersection density, conflict areas, measures for traffic calming) Traffic use (traffic flow of vehicles, cyclists, pedestrians, parked vehicles, crime risk / facial recognition, difficulty of navigational task) Environmental influences (complexity of visual field, ambient luminance, weather type, colour rendition) Visual guidance, traffic control 1
