“…This author affirms that the ‘rise of light-emitting diodes (LEDs) or the capitalist transformation of the nocturnal realm’ are usually not well understood. Therefore, we would want to consider new articles that are helping to improve these valid concepts or approaches and its lacks, for example, the modelling research conducted by Ziou and Kerouh (2018) for smart cities, or by Dominoni and Nelson (2018) highlighting the relevance of integrative studies across taxa, biological functions and scientific disciplines from the urban ecology approach. In this line, we strongly consider excellent contributions which can afford: (i) the effects of construction region environments on night-time brightness considering the regional economic development levels (Wang et al, 2019); (ii) the definition of the city boundaries with dramatic impacts on the scaling dynamic of the night-time light (Operti et al, 2018) and (iii) the combination of technical studies (e.g.…”

Light pollution is the consequence of elevated lighting emitted by human-made artefacts to the lower atmosphere. Recently, there have been major advances in the assessment and mitigation of light pollution impacts on humans and the natural ecosystems. Severe negative impacts of light pollution have been highlighted while very few mitigation measures have been implemented. People (scientists, policymakers or stakeholders) interested in light pollution may not have a holistic perspective of the problem, and also there is a need for incorporating social and natural dimensions. Therefore, the main goal of this paper is to review the literature on light pollution using ISI Web of Science by paying attention to the (i) type of publication, year and journal; (ii) impacts on specific elements; (iii) location and (iv) methods used. Our results indicated that the elevated number of papers come from a diverse range of disciplines, methods, places and scales. It is clear that light pollution is getting enough attention from the scientific community but decisions on the implementation of mitigation measures are left with the stakeholders, ordinary inhabitants, policymakers and politicians. Nevertheless, light pollution is having impacts on the health of humans and the natural ecosystem as perceived by experts and inhabitants having divergent perspectives. Thus, light pollution is multifaceted but difficult to be faced, mitigated and not holistically understood. This review paper groups the total impacts of light pollution on the Earth presents some contradictory results, summarises mitigation measures, and provides specific future research directions.

“…Satellite images, the visual equivalent of information perceived by a sensor, can be used to provide information about artificial nighttime radiation. Due to artificial night radiation, the impact area of atmospheric pollution increases [51,52,6]. Urban studies should include a strong foundation of analysis that allows for an interdisciplinary diagnosis to describe the various conditions of urban settlements [53].…”

“…The smart city concept has brought up many technological and scientific problems, including light pollution. Light pollution, which occurs as a direct result of incorrect external lighting, has various negative effects on the economy, ecology and health [6]. Light pollution has a large number of negative effects on individuals, ecosystems, astronomy and energy consumption, just as it is caused by sound, garbage and chemical products.…”

With the developing technology and increasing urbanization, many problems have started to arise in the use of energy resources and nature. In addition to environmental effects, energy-saving considerations constitute the main purpose of any proposed smart system. In outdoor lighting, along with the use of energy-efficient bulbs, the lighting should be done with the right method and the right way. In addition to these, an intelligent system integrated with an automatic control mechanism is needed. Incorrect outdoor lighting causes unnecessary energy consumption as well as light pollution and CO2 emission. These situations have negative consequences on both mental and physical health of the human, as well as on other living creatures and nature. Therefore, smart outdoor lighting systems offer an essential solution in preventing negative consequences that may occur with incorrect outdoor lighting. In this study, outdoor lighting requirements, light pollution and smart cities are examined in detail and the smart outdoor lighting systems within the scope of the smart cities are emphasized. As a result, the importance and necessity of the smart outdoor lighting system which provides energy-efficient and environmentally friendly structures by enabling street lamps to work smartly and efficiently are outlined.

“…Turn off street lighting: streetlights are equipped with motion sensors that turn off the lights when there is no need for light. Such practices reduce the light pollution caused by streetlights [30]. Warning light: flashing amber lights placed on the pavement in front of the pedestrian sidewalk increases the safety of pedestrians [31].…”

“…Materials such as wood, stucco, masonry, metal, or any material that absorbs vehicle-generated noise may also be used [44]. Use of full cutoff fixtures to eliminate light above the horizontal level: this fixture reduces light pollution from streetlights as it focuses the light downwards, thus preventing light "leaks" at or above 90 degrees [30]. Advance stop line and sign: a stop line and a sign marked/placed in advance of crosswalks to improve the safety and visibility of pedestrians [31].…”

A Holistic Intersection Rating System (HIRS)—A Novel Methodology to Measure the Holistic Operational Performance of Signalized Urban Intersections

et al. 2021

Signalized urban intersections are key components of urban transportation networks. They are traditionally viewed and designed as primarily motorized traffic facilities, and thus their physical and operational designs have traditionally aimed at maximizing traffic throughput subject to constraints dictated by vehicular safety requirements and pedestrian crossing needs. Seen from a holistic viewpoint, urban intersections are hubs or effective centers of community activities of which traffic flow is only one. Those hubs have direct and indirect impacts on the overlapping traffic functionalities, the environment, public health, community wellbeing, and the local economy. This study proposes a new rating system, the Holistic Intersection Rating System (HIRS), aimed at appraising signalized intersections from a more inclusive viewpoint. This appraisal covers traffic functionality, sustainability, and public health and community wellbeing. This rating system can be used as a guide to conceive, plan, or design new intersections or revamp existing ones. HIRS rates signalized urban intersections based on the level of use of relevant enabling technologies, and the physical and operational designs that allow those intersections to operate holistically, thus leading to a more human-centric and sustainable operational performance. HIRS was validated using a panel of experts in construction, transportation, and public health. The Relative Importance Index (RII) method was used to weigh the HIRS features. The rating system was piloted on a sample of 20 intersections in different cities in the UAE. The results revealed glaring gaps in services to or the consideration of pedestrians, cyclists, and nearby households. The sample intersections scored a mean of 32% on the public health and community wellbeing section, 37% on the pedestrian subsection, and 15% on the cyclist subsection. Such relatively low scores serve as indicators of areas for improvements, and if mapped to their specific features and their relative weights, specific physical and operations designs and technology integration can be identified as actionable items for inclusion in plans and/or designs.
