  Title Impressions of Lighting in Public Squares After Dark Type Journal Article
  Year 2017 Publication Environment & Behavior Abbreviated Journal Env. & Behav.  
  Volume 43 Issue 3 Pages 227-254  
  Keywords Psychology; public lighting; public safety; security; crime; perception; outdoor lighting  
  Abstract Lighting may affect impressions of public squares. Following studies on office interior lighting, the present research manipulated three modes of lighting—non-uniform–uniform, peripheral–overhead, and dim–bright—in three virtual squares. One study had 32 participants (15 men, 17 women) judge the spaciousness and privacy of each of the 24 public squares. A second study had a different group of 30 participants (16 men, 14 women) rate the appeal, safety from crime, and excitement of each square. Study 1 found that judged spaciousness increased with uniform and bright lighting, and that privacy increased with non-uniform, dim, and peripheral lighting. Study 2 found that rated appeal increased with uniform and bright lighting, as did safety from crime and excitement. Across the two studies, the uniform and bright lighting conditions contributed most to the kinds of favorable experiences people might expect to have in public spaces after dark.

  Title A study on selecting of Light Cutoff Panel depending on the installation condition using the lighting simulation Type Journal Article
  Year 2016 Publication Journal of the Korea Academia-Industrial cooperation Society Abbreviated Journal Journal of the Korea Academia-Industrial cooperation Society  
  Volume 17 Issue 2 Pages 246-251  
  Keywords Lighting; Light cutoff panel; Light pollution; Light trespass; Relux; Security light  
  Abstract The use of security lighting that emits spill light is considered a cause of light trespass problems in the residential areas. Therefore, a cutoff panel was installed as an alternative way to reduce light trespass. On the other hand, it has another problem in that it is less effective and is not good enough for aesthetics and safety. In this study, a light cutoff panel was designed and manufactured to reduce the light trespass, and the structure of a proper light cutoff panel was studied. Using a goniophotometer, the light distribution file (IES file) was extracted and the characteristics of light distribution were analyzed using the RELUX program. The results showed that the reduction of spilt light in the backward direction was decreased significantly for all types of light cutoff panels except the coated globe. In the case of a black powder coated light cutoff panel, the forward light caused by light reflected from the surface of the light cutoff panel was also reduced, which means that the black powder coated light cutoff panel is effective in the performance of light cutoff in the forward and backward directions. In addition, the coated glove increased the spilt light in the forward and backward directions because it reflects the upward light to go down. A 90 % accuracy between the measurement value of light trespass and the expected value of the light trespass was obtained from a simulation.

  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 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 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 Effects of road lighting on motorways Type Journal Article
  Year 2009 Publication Traffic Injury Prevention Abbreviated Journal Traffic Inj Prev  
  Volume 10 Issue 3 Pages 279-289  
  Keywords Lighting; Public Safety; Security  
  Abstract OBJECTIVES: The study has three objectives. The first is to investigate how the effect of road lighting on motorway accidents varies with different weather and road surface conditions. The second is to evaluate the future benefit of road lighting as a safety measure on motorways. The third is to evaluate the need for further research in the field of motorway lighting. METHOD: This article presents a cross-sectional study of the effects of road lighting on motorways mainly in The Netherlands. The main source of data is a Dutch database of accidents covering the period 1987-2006, but British and Swedish data are also used. RESULTS: The effect of road lighting on motorways is found to be greater in The Netherlands than in Great Britain or Sweden. Reasons for this are not known. Effects are found to vary according to background characteristics and are lesser during precipitation than during fine weather and on wet road surfaces than on dry surfaces. No effect of road lighting is found during fog. Collision with light poles constitutes a large number of accidents on lit motorways and reduces the safety effect of road lighting. CONCLUSIONS: The effect of road lighting on injury accidents during darkness is found to be very high (-49%) on Dutch motorways. However, the effect seems to vary between countries. Collisions with light poles reduce the effect of road lighting. Road lighting will probably be an effective safety measures on motorways for many years. In the long term, however, the benefit of road lighting will probably be reduced along with the implementation of new vehicle and road technology. Modern technology permits a continuous adaptation of luminance levels to optimize the effect of road lighting on safety while at the same time minimizing energy consumption. However, more detailed knowledge concerning the effects of road lighting at different lighting levels is needed in order to use this technology effectively. Alternative or additional measures like LED guide lights and light road surfaces also need to be evaluated.
