Title Social Impact of Connected Landmark Lighting: A Social Sensing Approach Type Journal Article
Year 2020 Publication IEEE Internet of Things Magazine Abbreviated Journal IEEE Internet Things M.
Volume (up) 3 Issue 1 Pages 64-67
Keywords Lighting; Society
Abstract The benefits of using light emitting diode (LED) lighting for landmarks extend beyond energy savings to the use of illumination for creating visual identity, placemaking, and increasing tourism. While measuring energy consumption is possible with metering technologies, thereby quantifying savings in energy costs, quantification of the social impact of landmark lighting is not straightforward. Measuring and monitoring social impact metrics is key to stakeholders investing in new connected LED lighting systems or upgrades of conventional lighting in order to realize the benefits of lighting that are beyond energy sustainability. We consider social sensing as an approach to quantifying social impact of landmark lighting. Using lighting at the Empire State Building and Bay Bridge as case studies, social sensing querying and data analytics aspects are presented. A number of practical lessons and technical directions for the use of social sensing in connected landmark lighting are then laid out.

Title NightLife: A cheap, robust, LED based light trap for collecting aquatic insects in remote areas Type Journal Article
Year 2016 Publication Biodiversity Data Journal Abbreviated Journal Bdj
Volume (up) 4 Issue Pages e7648
Keywords Animals; Ecology; Lighting
Abstract Background

There are approximately one hundred thousand aquatic insect species currently known to science and this figure is likely a significant underestimation. The ecology of aquatic insect groups has been studied due to their role as bioindicators of water quality and in the case of Diptera, their role as vectors of disease. Light trapping targets emergent adults, using mercury vapour bulbs or actinic fluorescent tubes, however these light sources are unsuitable for sampling remote regions due to their power requirements, which limit their mobility. Most insects studied have three types of photoreceptors corresponding to UV, blue and green light.

New information

We describe the NightLife: a cheap, robust, portable, LED based light source which targets insect trichromatic vision, is capable of autonomous operation and is powered by a single AA battery. Field trials show that the NightLife is capable of collecting sufficient samples of 12 insect orders, including all aquatic orders commonly collected by traditional light trapping and compares favourably with actinic fluorescent tubes and white LEDs. Future development in LED technology will likely result in LEDs replacing traditional light sources for collecting insects more widely.

Title Method to improve the survival of night-swarming mayflies near bridges in areas of distracting light pollution Type Journal Article
Year 2017 Publication Royal Society Open Science Abbreviated Journal R. Soc. open sci.
Volume (up) 4 Issue 11 Pages 171166
Keywords Animals; Lighting
Abstract Numerous negative ecological effects of urban lighting have been identified during the last decades. In spite of the development of lighting technologies, the detrimental effect of this form of light pollution has not declined. Several insect species are affected including the night-swarming mayfly Ephoron virgo: when encountering bridges during their mass swarming, these mayflies often fall victim to artificial lighting. We show a simple method for the conservation of these mayflies exploiting their positive phototaxis. With downstream-facing light-emitting diode beacon lights above two tributaries of the river Danube, we managed to guide egg-laying females to the water and prevent them from perishing outside the river near urban lights. By means of measuring the mayfly outflow from the river as a function of time and the on/off state of the beacons, we showed that the number of mayflies exiting the river's area was practically zero when our beacons were operating. Tributaries could be the sources of mayfly recolonization in case of water quality degradation of large rivers. The protection of mayfly populations in small rivers and safeguarding their aggregation and oviposition sites is therefore important.

Title Visualizing Multilayered Geospatial Data In Virtual Reality To Assess Public Lighting Type Journal Article
Year 2020 Publication ISPRS – International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences Abbreviated Journal Int. Arch. Photogramm. Remote Sens. Spatial Inf. Sci.
Volume (up) Xliii-B4-2020 Issue Pages 623-630
Keywords Lighting; Instrumentation; Vision
Abstract With the improvement and proliferation of virtual reality devices, their use for research and professional activity is broadening,fostering the advent of the field of immersive analytics, as is their acceptance among consumers. Other than the heightened sense of immersion into visualized data they provide, they also make displays of much larger apparent size and different positioning practical than what would be possible otherwise. Drawing on these benefits, we implemented a development of Multiple and Coordinated Displays (MCVs) for geovisualization that stacks different layers of data above each other, tilted for legibility. In a formal experiment, we evaluated it and two other, comparable MCV methods implemented in VR for their usefulness in analyzing public perception and soliciting public feedback regarding urban street lighting. In that field, the direction has recently been shifting from purely systemic development to a participatory approach, thus our investigation was into how a system like this could facilitate participation that can yield actionable results. Previous analysis of interaction data and usability questionnaires reveals preferences for certain systems depending on user characteristics, with the stack system showing a slight advantage over a grid of layers and especially over temporal multiplexing. We show that regardless of MCV variation, participants were able to analyze and provide feedback on public lighting situations that can directly contribute to urbanist work. The MCV approach further aided in understanding their choices, as eye-tracking allowed us to analyze attention to individual data layers.
