Resumen
The design and operation of multifunctional infrastructures for public lighting as well as their impact on the urban environment and citizens? life is today of great interest. The cost of energy for public lighting is often an issue for the budget of municipalities. Furthermore, researchers? and designers? attention is increasingly focused on aspects of public lighting not directly valuable through economic factors. Starting from the ?quality? of the light environment, looking at citizens? visual comfort, the light has to be considered as an instrument to improve the urban context and objects therein (including buildings). Indeed, urban degradation (lack of infrastructures, maintenance, services, etc.) is linked to the poor quality of everyday issues, such as traffic, pollution, noise, lack of information, long times to access focal points, and the lack of safety. Simultaneously, in many areas, the potential related to the valorization of historical heritage is often underexploited. The installation of efficient lighting systems coupled with the implementation of ICT solutions can provide economic, social, and health benefits, energy efficiency, and visual comfort. On the other hand, as for indoor lighting, these systems can be expensive, not easy to maintain, and not as efficient as expected. The aim of this Special Issue was to investigate the problems and advantages of smart urban lighting systems in more detail. This Special Issue included 6 papers of the 10 submitted papers.
