  Title Colors of attraction: Modeling insect flight to light behavior Type Journal Article
  Year (down) 2018 Publication Journal of Experimental Zoology. Part A, Ecological and Integrative Physiology Abbreviated Journal J Exp Zool A Ecol Integr Physiol  
  Volume 329 Issue 8-9 Pages 434-440  
  Keywords Animals; ecology; Lighting  
  Abstract Light sources attract nocturnal flying insects, but some lamps attract more insects than others. The relation between the properties of a light source and the number of attracted insects is, however, poorly understood. We developed a model to quantify the attractiveness of light sources based on the spectral output. This model is fitted using data from field experiments that compare a large number of different light sources. We validated this model using two additional datasets, one for all insects and one excluding the numerous Diptera. Our model facilitates the development and application of light sources that attract fewer insects without the need for extensive field tests and it can be used to correct for spectral composition when formulating hypotheses on the ecological impact of artificial light. In addition, we present a tool allowing the conversion of the spectral output of light sources to their relative insect attraction based on this model.

  Title Investigation of flashing and intensity characteristics for vehicle-mounted warning beacons Type Journal Article
  Year (down) 2018 Publication Accident Analysis & Prevention Abbreviated Journal Accident Analysis & Prevention  
  Volume 119 Issue Pages 23-28  
  Keywords Security; Public Safety; Lighting  
  Abstract Reducing the potential for crashes involving front line service workers and passing vehicles is important for increasing worker safety in work zones and similar locations. Flashing yellow warning beacons are often used to protect, delineate, and provide visual information to drivers within and approaching work zones. A nighttime field study using simulated workers, with and without reflective vests, present outside trucks was conducted to evaluate the effects of different warning beacon intensities and flash frequencies. Interactions between intensity and flash frequency were also analyzed. This study determined that intensitiesof 25/2.5 cd and 150/15 cd (peak/trough intensity) provided the farthest detection distances of the simulated worker. Mean detection distances in response to a flash frequency of 1 Hz were not statistically different from those in response to 4 Hz flashing. Simulated workers wearing reflective vests were seen the farthest distances away from the trucks for all combinations of intensity and flash frequency.

  Title The association between correlated colour temperature and scotopic/photopic ratio Type Journal Article
  Year (down) 2018 Publication Lighting Research & Technology Abbreviated Journal Lighting Research & Technology  
  Volume 35 Issue 10 Pages 1365-1374  
  Keywords Vision; Lighting  
  Abstract The scotopic/photopic ratio (S/P) is a parameter that may be considered in the design of road lighting. This paper compares the S/P ratio and correlated colour temperature (CCT) for 297 light source spectra identified in IES Technical Memorandum TM-30-15 to test the assumption that higher S/P ratios demand higher CCTs. The results suggest that, for a given lamp type, there is a strong association between S/P ratio and CCT, and hence that for a given CCT only a small variation in S/P ratio is available. However, the results also suggest that a larger variation in S/P ratio is possible if the lighting designer is able to consider a change in lamp type.

  Title Light Pollution: Is there an Environmental Kuznets Curve? Type Journal Article
  Year (down) 2018 Publication Sustainable Cities and Society Abbreviated Journal Sustainable Cities and Society  
  Volume 42 Issue Pages 337-343  
  Keywords Remote Sensing; Economics; Lighting  
  Abstract Light pollution is ranked high among recent forms of environmental degradation. While there have been many studies focusing on the diverse effects of artificial lighting on human health, wild life, etc., studies related to the social-economic impact of light pollution have been neglected. In the current paper, we assessed the relationship between economic development and light pollution. Using collected field data of illuminance levels as a measure of light pollution and land prices as an indicator of economic development, we drew conclusions about the effects of economic development on light pollution. The results did not show an inverted-U relationship between the two variables, hence denouncing the Environmental Kuznets Curve (EKC) theory. A regression analysis test showed an R-squared value of 0.322 at p > 0.215. Looking at the obtained results, which show no statistical significance between the two variables, we advise that local light pollution regulation laws and policies be equally stringent throughout districts/cities, regardless of economic status.
