  Title How Dark Is Dark? Bright Lights, Big City, Racial Profiling Type Journal Article
  Year 2016 Publication Review of Economics and Statistics Abbreviated Journal Review of Economics and Statistics  
  Volume 98 Issue 2 Pages 226-232  
  Keywords Psychology; Public Safety; Society  
  Abstract Grogger and Ridgeway (2006) use the daylight saving time shift to develop a police racial profiling test that is based on differences in driver race visibility and (hence) the race distribution of traffic stops across daylight and darkness. However, urban environments may be well lit at night, eroding the power of their test. We refine their test using streetlight location data in Syracuse, New York, and the results change in the direction of finding profiling of black drivers. Our preferred specification suggests that the odds of a black driver being stopped (relative to nonblack drivers) increase 15% in daylight compared to darkness.

  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 Factors related to the risk of pedestrian fatality after a crash in Spain, 1993–2013 Type Journal Article
  Year 2019 Publication Journal of Transport & Health Abbreviated Journal Journal of Transport & Health  
  Volume 12 Issue Pages 279-289  
  Keywords Public Safety  
  Abstract Introduction

The aim of this study was to quantify the magnitude of association between pedestrian fatalities during the first 24 h after a crash and pedestrian-, driver-, vehicle- and environment-related characteristics in Spain from 1993 to 2013.

Methods

Data were analyzed for all 203,622 traffic crashes involving a pedestrian and a motor vehicle recorded in the Spanish Registry of Road Crashes with Victims. After multiple imputation for missing values, crude (CMRR) and adjusted mortality rate ratios (AMRR) were obtained for each variable with Poisson regression models.

Results

Pedestrian risk of death after a crash increased nearly exponentially with pedestrian age. Male sex, committing an infraction and having a physical defect were also associated with a higher risk of death (AMRR 1.27, 95%CI 1.17–1.37 for physical defect). Regarding driver-related factors associated with pedestrian fatalities, visual defects (AMRR 1.21, 95%CI 1.08–1.37) and the commission of a speed infraction (AMRR 2.59, 95%CI 2.43–2.76) increased the risk. Heavy vehicles (trucks, vans, buses) and the presence of passengers were also associated with a higher risk of pedestrian death. The risk of pedestrian death was lower for crashes that occurred between 12:00 and 14:00, in good light conditions, at intersections, and when the pedestrian was on a sidewalk. Risk was higher in crashes in rural areas with fewer than 5000 inhabitants.

Conclusions

We identified several factors strongly associated with the risk of pedestrian fatality; some of these factors are analyzed here for the first time. This knowledge is potentially useful in the design and prioritization of measures intended to increase pedestrian safety.

  Title Driving in the Dark: Designing Autonomous Vehicles for Reducing Light Pollution Type Journal Article
  Year 2019 Publication Science and Engineering Ethics Abbreviated Journal Sci Eng Ethics  
  Volume Issue Pages 1-17  
  Keywords Society; Darkness; Planning; Public Safety; Design for values  
  Abstract This paper proposes that autonomous vehicles should be designed to reduce light pollution. In support of this specific proposal, a moral assessment of autonomous vehicles more comprehensive than the dilemmatic life-and-death questions of trolley problem-style situations is presented. The paper therefore consists of two interrelated arguments. The first is that autonomous vehicles are currently still a technology in development, and not one that has acquired its definitive shape, meaning the design of both the vehicles and the surrounding infrastructure is open-ended. Design for values is utilized to articulate a path forward, by which engineering ethics should strive to incorporate values into a technology during its development phase. Second, it is argued that nighttime lighting-a critical supporting infrastructure-should be a prima facie consideration for autonomous vehicles during their development phase. It is shown that a reduction in light pollution, and more boldly a better balance of lighting and darkness, can be achieved via the design of future autonomous vehicles. Two case studies are examined (parking lots and highways) through which autonomous vehicles may be designed for “driving in the dark.” Nighttime lighting issues are thus inserted into a broader ethics of autonomous vehicles, while simultaneously introducing questions of autonomous vehicles into debates about light pollution.

  Title An efficiency evaluation of radar‐based obstruction lights controlling at a wind turbine test site Type Journal Article
  Year 2019 Publication Wind Energy Abbreviated Journal  
  Volume 22 Issue 4 Pages  
  Keywords Lighting; Public Safety; Planning  
  Abstract In this study, an obstruction lights controlling (OLC) system based on a Terma SCANTER 5000 radar has been installed at a test centre for large wind turbines. The objective of this study was to evaluate the efficiency of the OLC system and to improve this efficiency by introducing new technological features. Once the first assessment had been carried out, new software with improved tracking functionalities was installed to the radar. With the new software, a second assessment was made to compare the new performance to the old one. To analyse the tracks, geographic information system (GIS) tools have been used. A new MATLAB script was developed to automate the assessment as well as to gather data on the tracks. These data sets were used to improve the system performance by introducing a radar cross section (RCS)/speed filter. The outcome of the study is a filter that can be implemented on the radar system to improve the efficiency of the system and reduce the time that obstruction lights need to be on for by 62.59%, without compromising the integrity of the system.
