  Title New nighttime roadway lighting documentation applied to public safety at night: A case study in San Antonio, Texas Type Journal Article
  Year 2019 Publication Sustainable Cities and Society Abbreviated Journal Sustainable Cities and Society  
  Volume 46 Issue Pages 101459  
  Keywords Lighting; Public Safety; Security; Planning  
  Abstract Built environment and public safety professionals view street lighting as an important factor in improving the well-being of the community at night. Extant research that has examined the relationship between street lighting and public safety has found inconclusive or mixed results and has called for more extensive lighting metrics. Using new lighting measurement technologies and geographic information science, this study builds on previous work to demonstrate new metrics to consider when evaluating public safety, specifically crime and traffic accidents. Downtown San Antonio, Texas is used as a case study to explore illuminance levels on roadways and the driver’s eye, and how these metrics can be used to understand the lighting characteristics of where crime and traffic accidents occur. The findings indicate that the central downtown district in San Antonio has higher illuminance levels than the existing roadway lighting guidelines while the residential downtown neighborhoods have insufficient light levels. Statistical analysis reveals that roadway illuminance levels are higher in areas where no crime occurred and driver’s eye illuminance levels are lower in areas with no traffic accidents. The findings prove the usefulness of new lighting documentation techniques and support the importance of considering illuminance metrics when assessing crime and traffic accidents at night.

  Title Contentious Light: An Analytical Framework for Lighting Conflicts Type Journal Article
  Year 2018 Publication International Journal of Sustainable Lighting Abbreviated Journal  
  Volume 20 Issue 1 Pages 62-77  
  Keywords Society; Lighting; Planning  
  Abstract This paper takes into view the broad range of contemporary conflicts regarding outdoor lighting. It proposes a working-definition that allows for differentiating lighting conflicts from other forms of lighting-related contention, as well as an analytical framework that allows for the structured description of individual lighting conflicts, and the comparative analysis of multiple cases. The analytical framework was developed based on the social-scientific analysis of media reports of existing conflict cases in Europe and North America, and informed by existing knowledge from the fields of lighting and conflict studies. A central challenge for developing such a framework is dealing with the high level of contingency and complexity of lighting conflicts. The framework reduces this complexity by focusing its field of vision to those aspects that are directly related to the lighting and its contestation. For each of these aspects, it provides sets of descriptive variables that allow for describing the conflicts’ individuality in a standardized – and thus comparable – way. The framework strictly separates the regarded aspects from their judgment by the conflict parties, making it possible to contrast their views on one and the same lighting situation. A visual template supports the process of analysis. It allows for depicting individual cases in short, and for clearly identifying where perspectives differ. At the multiple-case level, the framework not only opens up possibilities for spatial and temporal comparisons of lighting conflicts and the subsequent development of typologies, but also for harnessing their potential for informing the development of more sustainable planning and policy approaches for artificial lighting.

  Title The benefits of light at night Type Journal Article
  Year 2019 Publication Building and Environment Abbreviated Journal Building and Environment  
  Volume 151 Issue Pages 356-367  
  Keywords Lighting; Society; Conservation  
  Abstract The use of light at night continues to increase. Simply put, this is because without light we are deprived of our premier sense, vision. By enabling vision the use of light at night delivers a number of benefits to people. Such benefits include greater safety for pedestrians and drivers, reduced fear of crime, more use of outdoor facilities after dark, enhanced economic growth and the creation of built and natural environments that are a source of beauty and entertainment. This suggests that the use of light at night is linked to some very basic human motivations which in turn means that people value such benefits and will not willingly abandon them. Fortunately, careful lighting design, soundly-based outdoor lighting standards and new lighting and sensor technology offer the possibility of providing the benefits of light at night while minimizing the impact on the environment.

  Title The role of ambient light level in fatal crashes: inferences from daylight saving time transitions Type Journal Article
  Year 2002 Publication Accident Analysis & Prevention Abbreviated Journal Accident Analysis & Prevention  
  Volume 34 Issue 4 Pages 487-498  
  Keywords Public Safety; Lighting  
  Abstract The purpose of this study was to estimate the size of the influence of ambient light level on fatal pedestrian and vehicle crashes in three scenarios. The scenarios were: fatal pedestrian crashes at intersections, fatal pedestrian crashes on dark rural roads, and fatal single-vehicle run-off-road crashes on dark, curved roads. Each scenario's sensitivity to light level was evaluated by comparing the number of fatal crashes across changes to and from daylight saving time, within daily time periods in which an abrupt change in light level occurs relative to official clock time. The analyses included 11 years of fatal crashes in the United States, between 1987 and 1997. Scenarios involving pedestrians were most sensitive to light level, in some cases showing up to seven times more risk at night over daytime. In contrast, single-vehicle run-off-road crashes showed little difference between light and dark time periods, suggesting factors other than light level play the dominant role in these crashes. These results are discussed in the context of the possible safety improvements offered by new developments in adaptive vehicle headlighting.

  Title A Global Perspective for Sustainable Highway Tunnel Lighting Regulations: Greater Road Safety with a Lower Environmental Impact Type Journal Article
  Year 2018 Publication International Journal of Environmental Research and Public Health Abbreviated Journal Int J Environ Res Public Health  
  Volume 15 Issue 12 Pages  
  Keywords Lighting  
  Abstract Tunnel lighting installations function 24 h a day, 365 days a year. These infrastructures have increased exponentially and now connect quite distant locations, even on different continents. This has led European administrations and international regulatory bodies to establish regulations for tunnel safety with the lowest environmental impact. However, until now, these regulations have almost exclusively focused on traffic safety, and relegated sustainability to the background. Even though they recognize the need to reduce energy consumption, they do not propose any tools for doing so. Given the impact of these installations and the lack of a specific regulatory framework, Asian countries will soon be forced either to update previous standards for tunnel lighting or elaborate new ones. A better understanding of the weaknesses of European regulations combined with a willingness to embrace innovation could position Asia as a world leader in the regulation of more sustainable road tunnels. The objective of this research was to improve the sustainability of tunnel lighting installations through new regulations or amendments to existing ones, without impairing the mental well-being of users, who could potentially be affected by energy-saving measures. Accordingly, this paper presents and analyzes a broad proposal for formulating tunnel lighting regulations. The originality of this proposal lies in the fact that it integrates road safety, lower environmental impact, and user well-being. Furthermore, it is expected to broaden the perspective of regulatory bodies and public administrations with regard to tunnel installations, which would ultimately enhance their sustainability.
