| Title | Evaluation of the Safety Performance of Continuous Mainline Roadway Lighting on Freeway Segments in Washington State | Type | Report | ||

| Abstract | Washington State Department of Transportation (WSDOT) evaluated continuous roadway lighting on mainline freeway segments in Washington State. An extensive literature review on the safety performance of roadway lighting was completed. As part of this research effort WSDOT developed multivariate random parameter (RP) models with specific lighting variables for continuous lighting on mainline freeway segments. Roadway lighting is often used as a countermeasure to address nighttime crashes and this research evaluates common assumption related to roadway lighting. The models developed for this research use crashes from the end of civil dusk twilight to the start of civil dawn twilight since lighting systems are of limited value outside these timeframes. Natural light conditions were estimated for crashes based on location and time of the crash event. Based on the RP results, the research team concludes that the contribution of continuous illumination to nighttime crash reduction is negligible. In addition to the findings on safety performance, a pilot LED project on US101 demonstrated that LED roadway lighting can significantly increase energy efficiency and environmental stewardship (e.g., reducing greenhouse gas emissions) while maintaining safety performance outcomes. The research team recommended modification to WSDOT design policy, including removal of the requirement of continuous mainline lighting and reduction of lighting where segment specific analysis indicates appropriate. | ||||

| Title | Human signatures derived from nighttime lights along the Eastern Alpine river network in Austria and Italy | Type | Conference Article | ||
| Year | 2016 | Publication |
Abbreviated Journal | ||
| Volume | Issue | Pages | |||

| Abstract | Understanding how human settlements and economic activities are distributed with reference to the geographical location of streams and rivers is of fundamental relevance for several issues, such as flood risk management, drought management related to increased water demands by human population, fluvial ecosystem services, water pollution and water exploitation. Besides the spatial distribution, the evolution in time of the human presence constitutes an additional key question. This work aims at understanding and analysing the spatial and temporal evolution of human settlements and associated economic activity, derived from nighttime lights, in the Eastern Alpine region. Nightlights, available at a fine spatial resolution and for a 22-year period, constitute an excellent data base, which allows one to explore in details human signatures. In this experiment, nightlights are associated to five distinct distance-from-river classes. Our results clearly point out an overall enhancement of human presence across the considered distance classes during the last 22 years, though presenting some differences among the study regions. In particular, the river network delineation, by considering different groups of river pixels based on the Strahler order, is found to play a central role in the identification of nightlight spatio-temporal trends. |

| Title | Reducing Acadia's Light Pollution | Type | Manuscript | ||
| Year | 2016 | Publication |
Abbreviated Journal | ||

| Abstract | Acadia National Park is among the most visited national parks in the United States, attracting millions of people per year. Thousands of those visitors come to the park for “astro-tourism,” as Acadia has become one of the premier stargazing locations on the east coast. There remains, however, the continued threat from light pollution from the surrounding communities that negatively affects Acadia's darkness, contributing to a lesser visitor experience and potentially harming native ecosystems. Although park management and community organizations have engaged in significant efforts to decrease Acadia's nighttime light levels and raise awareness among visitors and locals regarding the importance of darkness, the park still seek to continue to decrease light pollution. This report developed policy options that could help solve the long-term policy goal of decreasing nighttime lighting levels within and around Acadia while also using the International Dark-Sky Association's Dark-Sky Park designation requirements as a reasonable, short-term policy benchmark. Working within existing organizations, the policy options crafted to address Acadia’s nighttime lighting levels were analyzed both qualitatively through a criteria evaluation and quantitatively through a Benefit Cost Analysis. The options included 1) the formation of a Darkness Coalition within the League of Towns, 2) a reimagining of the Worcester Polytechnic Institute Dark-Sky Project into the Dark-Sky Taskforce, 3) the creation of a Lighting Consultant position paid through the Friends of Acadia Wild Acadia initiative, and 4) the combination of Coalition and the Taskforce into the League of Towns – Dark-Sky Partnership (LOT-DSP). The report recommends the adoption of Option 4 – the creation of the LOT – DSP. While this option does not provide the greatest estimated monetary net value compared to the Status Quo in the quantitative evaluation, it still provides an estimated benefit of about $105 million over the course of five years and is the strongest option in the qualitative analysis. The LOT – DSP provides the best opportunity for Acadia to achieve legitimate and long-lasting nighttime light level reduction. |

Abbreviated Journal | ||
| Volume | Issue | Pages | |||
| Keywords | Skyglow; Remote Sensing; Artificial light at night; United Kingdom; Great Britain | ||||
| Abstract | We can now present the most accurate ever picture of how much light is spilling up into Britain’s night skies. Detailed interactive maps have been created for England showing districts, counties, National Parks and Areas of Outstanding Natural Beauty (AONBs) and, at a wider scale, National Character Areas. Besides these, there are high-level maps available for Scotland and Wales, so that we can now present the most accurate ever picture of how much light is spilling up into Britain’s night sky. |

| Title | Sark in the Dark: Wellbeing and Community on the Dark Sky Island of Sark | Type | Book Whole | ||
| Year | 2016 | Publication |
Abbreviated Journal | ||
| Volume | Issue | Pages | |||
| Keywords | Society; ecopsychology; environmental psychology; psychology | ||||
| Abstract | Studies of the beneficial and transformative qualities of encounters with nature typically focus on ‘green’ or grounded nature. In 'Sark in the Dark', Ada Blair shifts this focus upwards to a refreshing encounter with the richness of the dark night sky. In this book, she documents the research she conducted while at the University of Wales Trinity Saint David into the culture and history of the world’s first designated Dark Sky Island. Through a series of interviews with Sark residents, as well as poignant self-reflections, Blair explores the importance of the dark sky on human wellbeing and community. | ||||
