Title Lighting for cycling in the UK—A review Type Journal Article
Year 2015 Publication Lighting Research & Technology Abbreviated Journal
Volume 49 Issue 3 Pages 381-395
Keywords Lighting; Planning; Public Safety
Abstract (down) While UK governments have recently sought to increase cycling activity, it remains a minority interest. One reason for this is the perceived danger of cycling on roads filled with traffic. There is statistical evidence to support this perception; for equal exposure, cyclists are more likely to be seriously injured than either drivers or pedestrians. Lighting has a role to play in reducing the hazards of cycling by enhancing the visibility and conspicuity of cyclists. Unfortunately, it is not at all clear that the current lighting regulations and recommendations for cycling and cyclists are the best that can be achieved or are even adequate for these purposes. A number of actions are suggested that should enable lighting’s contribution to the safety of cyclists to be realized.

Title Street Lighting and Public Safety: New Nighttime Lighting Documentation Method Type Journal Article
Year 2018 Publication ARCC Conference Repository Abbreviated Journal
Volume Issue Pages
Keywords Public Safety; Lighting
Abstract (down) While the rapid transition of street lighting technologies is occurring across the country for its promising benefits of high energy efficiency, higher intensity, long lamp life, and low maintenance, there is a lack of understanding on the impacts from street lighting’s physical characteristics on public safety. Nighttime lighting and its impact on the incidence of crime and roadway accidents has been investigated since the 1960s in the United States and the United Kingdom. However, prior research has not presented any scientific evidence such as quantified lighting characteristic data and its impacts on public safety because they relied on subjective survey inputs or over-simplified quantification of nighttime lighting conditions. To overcome the limitation of previous studies, extensive documentation of street lighting characteristics was conducted in downtown San Antonio, Texas, which adopts both conventional and new street lighting technologies. Two different sets of light level data were collected on roadways in order to measure the amount of light falling on the ground and on drivers’ eyes inside a car. Correlated color temperature and a color rendering index of nighttime lighting were recorded. The collected lighting data was mapped in a Geographic Information Systems database in order to spatially analyze lighting characteristics. The paper first highlights the potential issues with lighting analysis in previous studies. Next, the proposed research methodology to address these issues for both data collection and spatial analyses is explained. Finally, the preliminary documentation and analysis of street lighting characteristics are presented.

Title Research on the Lighting Performance of LED Street Lights With Different Color Temperatures Type Journal Article
Year 2015 Publication IEEE Photonics Journal Abbreviated Journal IEEE Photonics J.
Volume 7 Issue 6 Pages 1-9
Keywords Lighting; LED; light-emitting diodes; PC-LED; dark adaption; color perception; fog; skyglow
Abstract (down) While light-emitting diodes (LEDs) are a very efficient lighting option, whether phosphor-coated LEDs (PC-LEDs) are suitable for street lighting remains to be tested. Correlated color temperature (CCT), mesopic vision illuminance, dark adaption, color perception, fog penetration, and skyglow pollution are important factors that determine alight's suitability for street lighting. In this paper, we have closely examined the lighting performance of LED street lights with different color temperatures and found that low-color-temperature (around 3000 K) PC-LEDs are more suitable for street lighting.

Title A decision support system for assessment of street lighting tenders based on energy performance indicators and environmental criteria: Overview, methodology and case study Type Journal Article
Year 2019 Publication Sustainable Cities and Society Abbreviated Journal Sustainable Cities and Society
Volume 51 Issue Pages 101759
Keywords Lighting; Policy
Abstract (down) While LEDs are now the most efficient light sources, their adoption in the road lighting design has been delayed due to a variety of reasons such as malpractice, huge number of inappropriate luminaires, missing technical information and ineffective policies. An example is the, low luminous efficacy values, which confuse the decision makers for national roads. The new part of EN13201-5 describes many energy performance indicators, which are still not used in street light projects or in lighting simulation tools. The aim of this paper is a) to present the significance of using these indicators through a decision tool, capable to evaluate a number of lighting designs in a lighting tender and b) to propose an evaluation method as part of a future energy policy including environmental criteria. A case study is also presented. The results show that the aforementioned decision tool is necessary in order to evaluate the ranking of the corresponding offers. Thus, increased energy savings could be achieved together with environmental benefits. In the case examined, the best solution resulted in 72.1% energy savings and CO2 emission reduction.

Title Dark Matters: The Effects of Artificial Lighting on Bats Type Book Chapter
Year 2015 Publication Bats in the Anthropocene: Conservation of Bats in a Changing World Abbreviated Journal
Volume Issue Pages 187-213
Keywords Animals; bats; vertebrates; ecology; artificial light at night; climate change
Abstract (down) While artificial lighting is a major component of global change, its biological impacts have only recently been recognised. Artificial lighting attracts and repels animals in taxon-specific ways and affects physiological processes. Being nocturnal, bats are likely to be strongly affected by artificial lighting. Moreover, many species of bats are insectivorous, and insects are also strongly influenced by lighting. Lighting technologies are changing rapidly, with the use of light-emitting diode (LED) lamps increasing. Impacts on bats and their prey depend on the light spectra produced by street lights ; ultraviolet (UV) wavelengths attract more insects and consequently insectivorous bats. Bat responses to lighting are species-specific and reflect differences in flight morphology and performance ; fast-flying aerial hawking species frequently feed around street lights, whereas relatively slow-flying bats that forage in more confined spaces are often light-averse. Both high-pressure sodium and LED lights reduce commuting activity by clutter-tolerant bats of the genera Myotis and Rhinolophus, and these bats still avoided LED lights when dimmed. Light-induced reductions in the activity of frugivorous bats may affect ecosystem services by reducing dispersal of the seeds of pioneer plants and hence reforestation. Rapid changes in street lighting offer the potential to explore mitigation methods such as part-night lighting (PNL), dimming, directed lighting, and motion-sensitive lighting that may have beneficial consequences for light-averse bat specie.
