  Title Comparative Study of Road Lighting Efficiency in the Context of CEN/TR 13201 2004 and 2014 Lighting Standards and Dynamic Control Type Journal Article
  Year 2019 Publication Energies Abbreviated Journal  
  Volume 12 Issue 8 Pages 1-14  
  Keywords Economics; Energy; Lighting; Planning  
  Abstract This paper presents a comparative study of differences in energy consumption while applying 2004 and 2014 releases of the CEN/TR 13201 standard for lighting designs. Street lighting optimal design and its optimization is discussed. To provide a reliable comparison, optimal designs for a given representative set of streets were calculated. The optimization was performed by newly developed software. As a test bed, a set of streets was selected with varying physical and traffic characteristics. The energy consumption was measured on the same set of streets both statically, which assumed the same lighting levels throughout night, and with a dynamic control, which adjusted lighting based on traffic intensity. For experiments with the dynamic control, one year of traffic intensity data were used. The findings confirm increased economical impact of dynamic control for the 2014 standard, which results in significant energy saving.

  Title Designing digital displays and interactive media in today’s cities by night. Do we know enough about attracting attention to do so? Type Journal Article
  Year 2018 Publication Conscious Cities Anthology Abbreviated Journal  
  Volume Issue Pages  
  Keywords Commentary; Lighting  
  Abstract With the huge transformation in the development of digital screen technology and its consistently decreasing cost, digital billboards are progressively replacing traditional static, two-dimensional poster advertisements in our cities1. Previously, due to the substantial expenditure involved, they were only available to major international brands with vast promotional resources to build their brand fame. Today, however, they are being used increasingly by advertisers to deliver all kinds of messages from simple ones to more sophisticated, interactive storytelling. Soon, however, even newer ways of purchasing advertisements using computers will be introduced by the outdoor media industry to address the public, so potentially everybody will be able to rent out available advertising space and communicate the message. But are we ready for this next step? As there are no proper guidelines or regulations in place for this new medium in the urban realm, today we are facing issues such as no integration of the display’s location into the built environment, no specifications based on knowledge of human perception and the human centric design approach, no control over its content quality, and so called ‘display blindness’2 seems to be a common collective urban experience at night. Taking London as one of the most cutting-edge outdoor digital advertising environments in the world3 (with the largest number of these screens traditionally located in or in close proximity to Piccadilly Circus) this paper discusses various aspects of this new medium. Besides the layout and geometry of the space, it also focuses on navigation and attracting the visual attention of passers-by at night in a practical human oriented context. Additionally, questions regarding complex sensory, social, special and interactional issues and the necessity for interdisciplinary collaboration have been addressed.

  Title Design of Path Prediction Smart Street Lighting System on the Internet of Things Type Journal Article
  Year 2019 Publication Journal of the Chosun Natural Science Abbreviated Journal  
  Volume 12 Issue 1 Pages 14-19  
  Keywords Lighting  
  Abstract In this paper, we propose a system for controlling the brightness of street lights by predicting pedestrian paths, identifying the position of pedestrians with motion sensing sensors and obtaining motion vectors based on past walking directions, then predicting pedestrian paths through the route prediction smart street lighting system. In addition, by using motion vector data, the pre-treatment process using linear interpolation method and the fuzzy system and neural network system were designed in parallel structure to increase efficiency and the rough set was used to correct errors. It is expected that the system proposed in this paper will be effective in securing the safety of pedestrians and reducing light pollution and energy by predicting the path of pedestrians in the detection of movement of pedestrians and in conjunction with smart street lightings.

  Title Optimizing Lighting of Rural Roads and Protected Areas with White Light: A Compromise among Light Pollution, Energy Savings, and Visibility Type Journal Article
  Year 2019 Publication Leukos Abbreviated Journal Leukos  
  Volume in press Issue Pages 15502724.2019.1574138  
  Keywords Lighting; Energy; Skyglow; LED  
  Abstract The broad implementation of light emitting diode (LED) light sources in public lighting has become a revolution in recent years. Their low power consumption and good performance (extremely low onset time, long lifetime, high efficacy) make LEDs an optimal solution in most outdoor applications. In addition, the white light emitted by the vast majority of LEDs used in public lighting and their good color rendering improve well-being, comfort, and safety in cities, especially in commercial zones and urban centers. However, regulations on light pollution that have been developed in some countries in parallel to the introduction of LED lighting impose strong constraints to white light emission, which is present due to the higher Rayleigh scattering of short wavelengths. These regulations request filtering blue wavelengths in some protected areas and thus limit the projects to high- or low-pressure sodium sources or amber LEDs. In this work, the pros and cons of white and amber LED lighting in rural areas are analyzed and compared through simulations made on a typical rural lighting situation and considerations based on efficiency, visual performance, nonvisual effects, and light pollution. The most important conclusion is that Rayleigh scattering seems to prevail in the current considerations on light pollution, whereas other important aspects affecting safety and sustainability are are not considered. Accurate designs can decrease light pollution without constraints against white LEDs. The objective of this work is to provide evidence leading to consider light pollution from a more general perspective in the benefit of humans and the environment.
