Title Individual factors influencing the assessment of the outdoor lighting of an urban footpath Type Journal Article
Year 2011 Publication Lighting Research and Technology Abbreviated Journal Lighting Research and Technology
Volume 43 Issue 1 Pages 31-43
Keywords footpath lighting; pathway lighting; outdoor lighting; lighting perception
Abstract During the hours of darkness, the mobility of young women, the elderly and the disabled is limited in urban areas. In a field study possible predictors of the perceived visual accessibility and the perceived danger of an urban footpath were investigated. Eighty-one people individually walked along the footpath after dark. They subjectively assessed the environment and answered a questionnaire about personality and socio-demographics. Visual accessibility was predicted by visual field, environmental trust and brightness. Danger was predicted by the pleasantness of the lighting, gender, brightness and environmental trust. Consequently, the influence of individual characteristics, including the subjective judgments of brightness and hedonic tone and the personality dimension of trust in the physical environment, should be considered in the design of exterior lighting for urban footpaths.

Title Factors Affecting Sign Visibility, Conspicuity, and Legibility: Review and Annotated Bibliography Type Journal Article
Year 2017 Publication Interdisciplinary Journal of Signage and Wayfinding Abbreviated Journal
Volume 1 Issue 2 Pages 2-25
Keywords Lighting
Abstract This paper summarizes published research studies, technical reports and codes and standards related to the visibility (i.e., conspicuity and legibility) of signage. In the summary that follows, publications are grouped and discussed according to several different topics. First, the typographic and symbolic characteristics of signs and the information they carry are described (e.g., letter size, font selection, etc.); second, photometric, colorimetric and temporal properties of signs as they affect visibility; finally, environmental considerations (e.g., daytime versus nighttime viewing, whether a sign is located in a rural or urban area, etc.) as they influence sign design are reviewed. Annotated summaries of each publication in the literature review are included at the end of this paper.

Title Spillover health effects of energy efficiency investments: Quasi-experimental evidence from the Los Angeles LED streetlight program Type Journal Article
Year 2018 Publication Journal of Environmental Economics and Management Abbreviated Journal Journal of Environmental Economics and Management
Volume 88 Issue Pages 283-299
Keywords Human Health; LED; public health; outdoor lighting; Los Angeles; economics; energy efficiency; breast cancer; fossil fuel carbon emissions
Abstract Payback estimates of energy efficiency investments often ignore public health externalities. This is problematic in cases where spillover health effects are substantial, such as when the application of new technology alters environmental exposures. When health externalities are included in return on investment calculations, energy efficiency programs may look more or less attractive than suggested by conventional “energy savings only” estimates. This analysis exploits the quasi-experiment provided by the 2009 Los Angeles (LA) LED streetlight efficiency program to investigate the returns on investments inclusive of an originally estimated health externality. Using the synthetic control method, we find that the LED streetlight program is associated with a lagged increase in breast cancer mortality of 0.479 per 100,000. Inclusive of the effects of LEDs on breast cancer and avoided carbon emissions, the LA LED program provides a −146.2% 10-year return compared to +118.2% when health outcomes and carbon emissions are ignored.
