ADAPTIVE SYSTEMS IN ROAD LIGHTING INSTALLATIONS
The new revised European standards for road lighting will be published in July 2015 highlighting the importance of energy performance aspects in road installations. The adaptive lighting approach can increase energy saving and reduce the environmental impact if compared to traditional solutions with the same type of luminaires and installation layout. For these reasons, the next revision of the Italian standard on the selection of lighting classes will consider adaptive installation suggesting peculiar requirements and control strategies as supplement to the European standard requirements. The paper describes the development of a luminance and traffic detector for adaptive system and the results of measurements carried out in more than one year on two experimental road lighting installations representative of an high volume traffic road (starting lighting class M2) and of a medium volume traffic road (starting lighting class M3).
