  Title Road lighting research for drivers and pedestrians: The basis of luminance and illuminance recommendations Type Journal Article
  Year 2018 Publication Lighting Research & Technology Abbreviated Journal Lighting Research & Technology  
  Volume 50 Issue 1 Pages 154-186  
  Keywords Security; Public Safety; Lighting; Review  
  Abstract This article discusses quantitative recommendations for road lighting as given in guidelines and standards, primarily, the amount of light. The discussion is framed according to the type of road user, the driver and the pedestrian, these being the user groups associated with major and minor roads, respectively. Presented first is a brief history of road lighting standards, from early to current versions, and, where known, the basis of these standards. Recommendations for the amount of light do not appear to be well-founded in robust empirical evidence, or at least do not tend to reveal the nature of any evidence. This suggests a need to reconsider recommended light levels, a need reinforced by recent developments in the science and technology of lighting and of lighting research. To enable improved recommendations, there is a need for further evidence of the effects of changes in lighting: This article therefore discusses the findings of investigations, which might be considered when developing new standards.

  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 Effects of Overall Low-Beam Intensity on Seeing Distance in the Presence of Glare Type Journal Article
  Year 2000 Publication Transportation Human Factors Abbreviated Journal Transportation Human Factors  
  Volume 2 Issue 4 Pages 313-330  
  Keywords Public Safety; Vision  
  Abstract Previous studies have demonstrated that current low-beam headlamps do not provide adequate seeing distance for safety. Could this situation be improved by providing more total light from low-beam headlamps, leaving the relative distribution of light unchanged? Although such a proposal is probably not the best practical solution, it is important to consider some of the visual consequences of a general increase in light to analyze the overall problem of low-beam headlighting.

In a nighttime field study we measured seeing distance in the presence of glare as a function of headlamp intensity, always varying the intensity of the seeing light and glare light by the same proportion. Increasing intensity by a factor of about 3.8 increased seeing distance by about 17% for both young and old drivers. This result is consistent with predictions from quantitative vision modeling using veiling luminance to represent the disabling effects of glare. We also collected subjective estimates of discomfort glare and found, as expected, that the higher intensities produced substantially more discomfort.

Our findings suggest that, if objective visual performance is the only criterion, there is no clear upper limit to how intense low-beam headlamps should be. However, there may be a level at which people simply will not tolerate the subjectively discomforting effects of glare, or at which glare indirectly affects objective performance through its effects on subjective comfort. Because subjective discomfort, rather than objective visual performance, may be the limiting consideration for setting maximum glare levels, more research should be done to understand the nature and consequences of discomfort glare, including possible effects of subjective comfort on objective visual behavior.

  Title Under the Cover of Darkness: How Ambient Light Influences Criminal Activity Type Journal Article
  Year 2015 Publication Review of Economics and Statistics Abbreviated Journal Review of Economics and Statistics  
  Volume 97 Issue 5 Pages 1093-1103  
  Keywords Public Safety; Crime  
  Abstract We exploit daylight saving time (DST) as an exogenous shock to daylight, using both the discontinuous nature of the policy and the 2007 extension of DST, to consider the impact of light on criminal activity.Regression discontinuity estimates show a 7% decrease in robberies following the shift to DST. As expected, effects are largest during the hours directly affected by the shift in daylight. We discuss our findings within the context of criminal decision making and labor supply, and estimate that the2007 DST extension resulted in $59 million in annual social cost savings from avoided robberies.
