Objectives: The primary objective of the proposed series of urban outdoor lighting demonstrations is to validate prior research findings suggesting a role for enhanced perceptions of brightness and personal security under light sources varying in their spectral (color) content, and suggesting that pedestrian-level lighting in crosswalks and other conflict areas can enhance pedestrian safety by making them more visible to drivers in congested urban areas.

Introduction. Recent demographic trends suggest an increasing suburbanization of poor populations. Given that poor households are often unable to afford increasing housing prices in many urban areas they are increasingly moving to the suburbs. At the same time, suburbs often do not support the public transit needs of poor populations and access to jobs. Insufficient transit can also exacerbate recovery times after extreme weather events for vulnerable populations.
