  Title Road lighting and pedestrian reassurance after dark: A review Type Journal Article
  Year 2015 Publication Lighting Research and Technology Abbreviated Journal Lighting Research and Technology  
  Volume 47 Issue 4 Pages 449-469  
  Keywords (up) Security, psychology  
  Abstract This paper concerns road lighting for pedestrians and how this aids reassurance, their confidence when walking alone after dark. Evidence from past studies that lighting enhances reassurance is supported by the findings of an unfocussed approach that aimed deliberately to avoid focus on lighting or fear, thus to counter the unintended potential for focussed, quantitative methods to lead towards such a finding. Review of the characteristics of lighting suggests an optimum illuminance of 10 lux, of high S/P ratio, and aimed toward the pedestrian and natural elements of the environment, will enhance reassurance. Further research is needed to validate the optimum illuminance, the appropriate metric for characterising lamp spectral power distribution, and the most desirable aims of spatial distribution.

  Title Why Lighting Claims Might Well Be Wrong Type Journal Article
  Year 2017 Publication International Journal of Sustainable Lighting Abbreviated Journal Intl J of Sustainable Lighting  
  Volume 19 Issue 1 Pages 69-74  
  Keywords (up) Security; Crime; lighting; regulation  
  Abstract This paper gives some background to claims of benefit from road lighting and why large beneficial claims may be suspect. It places this in the context of general concerns about the unreliability of claims in science using knowledge gained, particularly from investigations in the field of health-care. It points to the need to plan, proceed and check science in unbiased and rigorous ways. It gives recommendations for more transparency, asks for clear protocols to be produced in advance, that clear reports are written which follow appropriate reporting guidelines and that the data is accessible.

  Title On-road experiment to assess drivers' detection of roadside targets as a function of headlight system, target placement, and target reflectance Type Journal Article
  Year 2015 Publication Accident; Analysis and Prevention Abbreviated Journal Accid Anal Prev  
  Volume 76 Issue Pages 74-82  
  Keywords (up) security; lighting  
  Abstract Adaptive headlights swivel with steering input to keep the beams on the roadway as drivers negotiate curves. To assess the effects of this feature on driver's visual performance, a field experiment was conducted at night on a rural, unlit, and unlined two-lane road during which 20 adult participant drivers searched a set of 60 targets. High- (n=30) and low- (n=30) reflectance targets were evenly distributed on straight road sections and on the inside or outside of curves. Participants completed three target detection trials: once with adaptive high-intensity discharge (HID) headlights, once with fixed HID headlights, and once with fixed halogen headlights. Results indicated the adaptive HID headlights helped drivers detect targets that were most difficult to see (low reflectance) at the points in curves found by other researchers to be most crucial for successful navigation (inside apex). For targets placed on straight stretches of road or on the outside of curves, the adaptive feature provided no significant improvement in target detection. However, the pattern of results indicate that HID lamps whether fixed or adaptive improved target detection somewhat, suggesting that part of the real world crash reduction measured for this adaptive system (Highway Loss Data Institute (HLDI), 2012a) may be due to the differences in the light source (HID vs. halogen). Depending on the scenario, the estimated benefits to driver response time associated with the tested adaptive (swiveling HID) headlights ranged from 200 to 380ms compared with the fixed headlight systems tested.

  Title Investigation of flashing and intensity characteristics for vehicle-mounted warning beacons Type Journal Article
  Year 2018 Publication Accident Analysis & Prevention Abbreviated Journal Accident Analysis & Prevention  
  Volume 119 Issue Pages 23-28  
  Keywords (up) 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 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 (up) 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.
