Advanced Adaptive Street Lighting Systems for Smart Cities

Abstract

This paper reports the results of a recently concluded R&D project, SCALS (Smart Cities Adaptive Lighting System), which aimed at the development of all hardware/software components of an adaptive urban smart lighting architecture allowing municipalities to manage and control public street lighting lamps. The system is capable to autonomously adjust street lamps’ brightness on the basis of the presence of vehicles (busses/trucks, cars, motorcycles and bikes) and/or pedestrians in specific areas or segments of the streets/roads of interest to reduce the energy consumption. The main contribution of this work is to design a low cost smart lighting system and, at same time, to define an IoT infrastructure where each lighting pole is an element of a network that can increase their amplitude. More generally, the proposed smart infrastructure can be viewed as the basis of a wider technological architecture aimed at offering value-added services for sustainable cities. The smart architecture combines various sub-systems (local controllers, motion sensors, video-cameras, weather sensors) and electronic devices, each of them in charge of performing specific operations: remote street segments lamp management, single street lamp brightness control, video processing for vehicles motion detection and classification, wireless and wired data exchanges, power consumptions analysis and traffic evaluation. Two pilot sites have been built up in the project where the smart architecture has been tested and validated in real scenarios. Experimental results show that energy savings of up to 80% are possible compared to a traditional street lamp system.

A Semantic Model for Interchangeable Microservices in Cloud Continuum Computing

“…Despite all benefits of cloud continuum computing frameworks, interoperability problem is a key unsolved challenge which needs to be addressed. This is because in light of emerging IoT solutions addressing the needs of domains such as intelligent energy management [15], smart cities [16], lighting [17,18] and healthcare [19], many different technologies and techniques offered by various providers have to be integrated with each other and even customised in most cases. In this regards, very limited research works [20][21][22][23][24][25], which concentrate on heterogeneous modern computing environments and the related interoperability issues have been conducted.…”

ICT Driven Smart Lighting Solution “iLIGHT” for Smart Cities: A Conceptual Framework

“…Let us further explore the Smart Lighting System for Smart Cities [12][13][14][15][16][17][18][19][20][21][22][23][24]. Refer figure 3 which has shown the typical architecture of Smart Lighting System.…”

A web-based control system for traditional street lighting that uses high-pressure sodium lamps

“…The IoT-based street lighting system has been enhanced to facilitate the construction of a smart city. Numerous works have combined the street lighting system with other components for this purpose, including a faulty streetlight detector [21], emergency buttons installed on light poles that send an emergency signal to the police station [22], camera units that manage the traffic signal [23], special sensors for traffic counting [24], human detectors that can alert authorities to probable theft at odd hours [25], and smart poles that equip cameras to detect and report any motion events [26]. The dimming performance of LED lamps is another important technology that researchers are interested in.…”
