  Title Lighting for cycling in the UK—A review Type Journal Article
  Year 2015 Publication Lighting Research & Technology Abbreviated Journal  
  Volume 49 Issue 3 Pages 381-395  
  Keywords Lighting; Planning; Public Safety  
  Abstract While UK governments have recently sought to increase cycling activity, it remains a minority interest. One reason for this is the perceived danger of cycling on roads filled with traffic. There is statistical evidence to support this perception; for equal exposure, cyclists are more likely to be seriously injured than either drivers or pedestrians. Lighting has a role to play in reducing the hazards of cycling by enhancing the visibility and conspicuity of cyclists. Unfortunately, it is not at all clear that the current lighting regulations and recommendations for cycling and cyclists are the best that can be achieved or are even adequate for these purposes. A number of actions are suggested that should enable lighting’s contribution to the safety of cyclists to be realized.

  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 Effects of Environmental Lighting Conditions on Operating Speeds on Urban Arterials Type Journal Article
  Year 2012 Publication Transportation Research Record: Journal of the Transportation Research Board Abbreviated Journal Transportation Research Record  
  Volume 2298 Issue 1 Pages 78-87  
  Keywords Lighting; Public Safety  
  Abstract Driver behavior is influenced by environmental lighting conditions on roads; in the literature, many studies report a reduced night–day accident ratio following improvements to lighting on different types of roads, with the results classified by severity and type of accident. Few studies, however, report the influence of lighting conditions on driver speed. This study investigates the principal factors that influence driver speed on arterial roads in Turin, Italy. The aim of this study was to analyze driver speed under different daylight and nighttime lighting conditions. Six arterial roads were selected for observation and the measurement of speeds and illuminance on the pavement surface. The results showed that illuminance, in addition to factors such as lane position, lane width, and the relevant speed limit, should be considered a variable that can influence driver speed. The study used a regression equation to predict operating speeds (V85) on urban arterials; the corresponding sensitivity analysis has made it possible to quantify the effects of the aforementioned variables on operating speed under different environmental lighting conditions.

  Title The role of lighting in road traffic collisions Type Journal Article
  Year 2020 Publication Lighting Research & Technology Abbreviated Journal Lighting Research & Technology  
  Volume 52 Issue 4 Pages 485-494  
  Keywords Public Safety  
  Abstract The paper reports a study that examines how to determine if a road traffic collision took place in daylight or in the dark. An innovative method was developed, based on solar altitude, to establish cut-off points of daylight and darkness determined from a study of daylight availability in England, Scotland and Wales. This approach provides a rigorous method to differentiate daytime and night-time collisions. The criteria were used in a study of the collisions reported in the STATS19 data set for the weeks either side of the clock changes that are necessary between Greenwich Mean Time and British Summer Time. By comparing periods with the same clock time either side of the time change, using the aforementioned method, it was possible to isolate collisions within the same time period that during one week occurred in darkness and in the other week in daylight. The initial finding was that there are 19.3% more collisions in the dark periods and there is an even greater increase (31.7%) in pedestrian injuries.

  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.
