Title Nighttime Visibility in Varying Moonlight Conditions Type Journal Article
Year 2019 Publication SAE Technical Paper 2019-01-1005 Abbreviated Journal
Volume Issue Pages
Keywords Public Safety; Moonlight; Vision
Abstract When the visibility of an object or person in the roadway from a driver’s perspective is an issue, the potential effect of moonlight is sometimes questioned. To assess this potential effect, methods typically used to quantify visibility were performed during conditions with no moon and with a full moon. In the full moon condition, measurements were collected from initial moon rise until the moon reached peak azimuth. Baseline ambient light measurements of illumination at the test surface were measured in both no moon and full moon scenarios. Additionally, a vehicle with activated low beam headlamps was positioned in the testing area and the change in illumination at two locations forward of the vehicle was recorded at thirty-minute intervals as the moon rose to the highest position in the sky. Also, two separate luminance readings were recorded during the test intervals, one location 75 feet in front and to the left of the vehicle, and another 150 feet forward of the vehicle. These luminance readings yielding the change in reflected light attributable to the moon. In addition to the quantitative measurement of light contributed by the moon, documentation to the change in visibility of objects and pedestrians located on the roadway were documented through photographs. Calibrated nighttime photographs were taken from the driver’s perspective inside the vehicle with low beam headlamps activated. The photographs were analyzed after testing to determine how the light intensity of the pixels in the photographs changed at each thirty-minute interval due to the additional light contribution from the moon. The results of this testing indicate that the quantifiable change in visibility distance attributable to added moonlight was negligible, and in real-world driving situations, the effect of additional illumination from a full moon would be unlikely to affect the detection of an object or pedestrian in or near the travel lane of the roadway.

Title Assessing Public Perceptions about Road Lighting in five Neighborhoods of Tirana, Albania Type Journal Article
Year 2019 Publication Abbreviated Journal
Volume Issue Pages
Keywords Public Safety; Psychology; Roadway lighting; Albania; Europe
Abstract Lighting is essential for sight, human health and well-being, emerging the need for assessing exterior lighting to better understand how far public is satisfied about exterior lighting. Exterior lighting was assessed in five major roads of the capital city of Tirana, Albania, in November 2017. Security, obstacle detection and visibility were evaluated using questionnaires for road lighting. The approximately 87 and 60 percent of respondents, respectively, were not able to detect a pavement obstacle after-dark and to distinguish a

familiar face at a distance of 5 m and 10 m along roads. Road lighting after-dark was unsatisfactory to 60 percent of respondents. These findings identified road lighting could be inadequate for users, requiring further investigation and new data collection of road lighting in neighborhoods of Tirana.

Title Pedestrian Lighting, Acceptable Levels of Light: A Pilot Project Type Journal Article
Year 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.
