Title Making sense of diodes and sodium: Vision, visuality and the everyday experience of infrastructural change Type Journal Article
Year 2019 Publication Geoforum Abbreviated Journal Geoforum
Volume 103 Issue Pages 95-104
Keywords Lighting; visual sensorium; United Kingdom
Abstract The recognition of vision as a powerful register for organising urban space locates lighting technologies at the heart of urban experience. Recently, scholars have established that lighting technologies shape not just what we see but how we see, drawing attention towards light as that ‘with which we see’. This article shifts attention from the role of lighting in shaping what and how people see, to how people make sense of changes to their visual sensorium—from what lighting infrastructures do to what is done with them. By following older residents living in the London Borough of Newham along routine travels on foot at night, I demonstrate how they make sense of the Council’s initiative to upgrade their 19,500 street-lamps with Light Emitting Diodes. I demonstrate how such infrastructural change exposes an uneven geographical distribution of and access to light and darkness with potentially detrimental consequences for the formation of public life after dark. Recognising how light infrastructures are reframed through everyday life, I demonstrate how LEDs do not necessarily produce their desired effects and how light clutter and light bleed might contribute to producing nocturnal atmospheres where people feel safe and confident. Broadening the understanding of how different technologies and light sources are important for the formation of inclusive nocturnal publics the article sets out a ‘politics of visibility’ that recognises the role of lighting in creating visibility for and of residents.

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 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 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 Impact of urban street lighting on road users’ perception of public space and mobility behavior Type Journal Article
Year 2019 Publication Building and Environment Abbreviated Journal Building and Environment
Volume 154 Issue Pages 32-43
Keywords Lighting; Psychology
Abstract Refitting public spaces with light-emitting diode (LED) technology in lieu of conventional luminaires bears the risk of compromising lighting quality that road users have already adapted to; this is because the LED technology has been well tested indoors, but it has not been necessarily evaluated outdoors. Further insight into the effects of street lighting on road users is necessary to resolve potential deficiencies of available technologies. This study compares the effects of three different lighting scenarios (conventional lighting, state-of-the-art LED, optimized LED) on road users via surveys (N = 598 persons) and observations (N = 1341 persons) in the city of Vienna. In terms of the uniformity of street illumination and the comfort it provides, the results show the positive effects of LED street lighting both on surveyed pedestrians and vehicle drivers. The observations of pedestrian walking behavior revealed an unexpected result—no significant differences were noted apart from a more centric walking path along the sidewalk under LED illumination, particularly with the optimized LED luminaire.
