  Title Road lighting and accidents: Why lighting is not the only answer Type Journal Article
  Year 2017 Publication Lighting Journal Abbreviated Journal  
  Volume 82 Issue 5 Pages 22-26  
  Keywords Lighting; Public Safety  
  Abstract Tony Price and Steve Fotios point out that while road lighting can be a significant counter measure to accidents, and that higher levels might help, the presence of road lighting does not guarantee all accidents will be avoided.

  Title Effect of illuminance and spectrum on peripheral obstacle detection by pedestrians Type Journal Article
  Year 2015 Publication Lighting Research & Technology Abbreviated Journal  
  Volume 49 Issue 2 Pages 211-227  
  Keywords Public Safety; Lighting  
  Abstract Obstacle detection is an important visual task for pedestrians. An experiment was carried out to measure the ability to detect peripheral obstacles under variations of illuminance and scotopic/photopic luminance ratio and with older and younger test participants. The LED array used in this work enabled scotopic/photopic ratio to be varied whilst chromaticity was held constant. The tests employed a full-scale model with dynamic fixation and walking to better simulate pedestrian experience than in past work. Detection performance increased with illuminance, reaching a plateau at 2.0 lux. A higher scotopic/photopic ratio improved obstacle detection but only at the lowest illuminance used in this study (0.2 lux). Older participants showed poorer obstacle detection performance than younger participants but again only at the lowest illuminance.

  Title The transition between lit and unlit sections of road and detection of driving hazards after dark Type Journal Article
  Year 2017 Publication Lighting Research & Technology Abbreviated Journal  
  Volume 51 Issue 2 Pages 243-261  
  Keywords Vision; Public Safety; Lighting; Planning  
  Abstract An experiment to investigate peripheral detection performance during a driver’s transition between lit and unlit sections of road was undertaken. The results suggest that when a driver moves from a lit to an unlit section of road their detection performance decreases almost immediately to that expected for the conditions of the unlit section and that there is no significant change in the subsequent 20-minute period. Tests were conducted at three luminances (0.1, 1.0 and 2.0 cd/m2): while an increase from 0.1 to 1.0 cd/m2 improved detection, a further increase to 2.0 cd/m2 did not. Lighting of two S/P ratios (0.65, 1.40) was examined at 1.0 cd/m2: this did not suggest an effect on detection performance. Taken together, these results suggest that, in the current context, visual performance reached a plateau at 1.0 cd/m2.

  Title What Happens in the Shadows: Streetlights and How They Relate To Crime Type Journal Article
  Year 2017 Publication Abbreviated Journal  
  Volume Issue Pages  
  Keywords Crime; Lighting  
  Abstract After finding in a previous report, “Streetlights in the City: Understanding the Distribution of Houston Streetlights,” that the city of Houston’s more than 173,000 streetlights were not evenly distributed throughout the city, this next report answers the question: do places with more streetlights have lower crime rates?

The findings complicate the common perception that more streetlights lead to fewer crimes. While there was some evidence that a particularly high density of streetlights can provide protective benefits, excluding those extremes provides a much muddier picture, suggesting that crime is a reflection of other neighborhood contexts. As such, cities should be cautious in expecting direct reductions in crime with the introduction of more streetlights.

  Title Reducing the environmental footprint of church lighting: matching façade shape and lowering luminance with the EcoSky LED Type Journal Article
  Year 2018 Publication International Journal of Sustainable Lighting Abbreviated Journal  
  Volume 20 Issue 1 Pages 1-10  
  Keywords Energy; Lighting; Remote Sensing  
  Abstract The lighting of the Church of the Three Kings in Logatec, Slovenia was replaced in 2014. The power of the installation was reduced 96% from 1.6 kW to 58 W, and spill light from the site was effectively eliminated. As a result, the church is no longer visible in nighttime satellite images of the area, indicating a reduction of waste light from the site of at least a factor of 30. This article discusses the concept of sustainability with regards to cultural heritage lighting, within the context of this example.
