Title Pedestrian Lighting, Acceptable Levels of Light: A Pilot Project Type Journal Article
Year (down) 2019 Publication Institute for Public Administration Abbreviated Journal
Volume Issue Pages
Keywords Lighting; Public Safety; Security
Abstract This pilot project study was intended to demonstrate that assessing the adequacy of an area’s pedestrian lighting need not be an expensive, time-consuming, or overly complicated process. Though the discussion of methods of pedestrian lighting can become quite technical and involved, as demonstrated in a 2016 IPA report on the topic, “Delaware Transportation Lighting Inventory & Assessment” (http://www.ipa.udel.edu/publications/transportationlighting-2016.pdf), simply observing and recording light levels in a given study area is quite straightforward.

Title Road lighting research for drivers and pedestrians: The basis of luminance and illuminance recommendations Type Journal Article
Year (down) 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 Investigation of flashing and intensity characteristics for vehicle-mounted warning beacons Type Journal Article
Year (down) 2018 Publication Accident Analysis & Prevention Abbreviated Journal Accident Analysis & Prevention
Volume 119 Issue Pages 23-28
Keywords 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 From global radiance to an increased local political awareness of light pollution Type Journal Article
Year (down) 2018 Publication Environmental Science & Policy Abbreviated Journal Environmental Science & Policy
Volume 89 Issue Pages 142-152
Keywords Remote Sensing; Public Safety; Animals
Abstract We present a novel transparent method to analyze measurements of the Suomi NPP (Suomi National Polar-orbiting Partnership) satellite in night vision, into luminous intensity and luminance on the community level, with a special focus to address light planners and non-experts, and for the first time, to further address politicians, decision-makers and law-makers, and governmental agencies. We checked the propagated efficiency of road lighting and its impact on luminous flux, and identified a waste of light emissions in the largest city of Switzerland, Zurich. We looked at security (issues like criminal acts) and found no correlation with communities’ luminous intensity. We assessed road safety (accidents) against local luminance and found no evidence of darkness being more risky when the overall distribution of illuminance on roads is considered. We screened crayfish habitats in the Canton of Zurich against local illuminance and found clear evidence of preferred darkness for the living. Based on this finding, we propose an upper limit for light immissions in the crayfish habitats. These four analyses have been chosen to demonstrate the usefulness of Suomi NPP's coverage in combination with our approach. We could apply it to ecological, social and economical topics. We hope others will follow and we can draw more attention of governments to take action to reduce the light pollution on local levels, like Langnau am Albis of Switzerland has exemplified.
