  Title Determining the potential safety benefit of improved lighting in three pedestrian crash scenarios Type Journal Article
  Year 2007 Publication Accident; Analysis and Prevention Abbreviated Journal Accid Anal Prev  
  Volume 39 Issue 3 Pages (up) 638-647  
  Keywords Lighting; Accidents, Traffic/*prevention & control/statistics & numerical data; Automobile Driving/*psychology; Darkness/*adverse effects; *Environment Design; Humans; Lighting/*standards; Prevalence; Risk; *Safety; Time; *Visual Perception; *Walking  
  Abstract The influence of light level was determined for three pedestrian crash scenarios associated with three adaptive headlighting solutions-curve lighting, motorway lighting, and cornering light. These results were coupled to corresponding prevalence data for each scenario to derive measures of annual lifesaving potential. For each scenario, the risk associated with light level was determined using daylight saving time (DST) transitions to produce a dark/light interval risk ratio; prevalence was determined using the corresponding annual crash rate in darkness for each scenario. For curve lighting, pedestrian crashes on curved roadways were examined; for motorway lighting, crashes associated with high speed roadways were examined; and for cornering light, crashes involving turning vehicles at intersections were examined. In the curve analysis, lower dark/light crash ratios were observed for curved sections of roadway compared to straight roads. In the motorway analysis, posted speed limit was the dominant predictor of this ratio for the fatal crash dataset; road function class was the dominant predictor of the ratio for the fatal/nonfatal dataset. Finally, in the intersection crash analysis, the dark/light ratio for turning vehicles was lower than for nonturning vehicles; and the ratio at intersections was lower than at non-intersections. Relative safety need was determined by combining the dark/light ratio with prevalence data to produce an idealized measure of lifesaving potential. While all three scenarios suggested a potential for safety improvement, scenarios related to high speed roadway environments showed the greatest potential.

  Title Limitations in drivers' ability to recognize pedestrians at night Type Journal Article
  Year 2005 Publication Human Factors Abbreviated Journal Hum Factors  
  Volume 47 Issue 3 Pages (up) 644-653  
  Keywords Vision; Public Safety; Adult; Age Factors; Aged; *Automobile Driving/psychology; Clothing; *Darkness; Female; Humans; Male; Middle Aged; Reaction Time; Task Performance and Analysis; Visual Perception  
  Abstract This study quantified drivers' ability to recognize pedestrians at night. Ten young and 10 older participants drove around a closed road circuit and responded when they first recognized a pedestrian. Four pedestrian clothing and two beam conditions were tested. Results demonstrate that driver age, clothing configuration, headlamp beam, and glare all significantly affect performance. Drivers recognized only 5% of pedestrians in the most challenging condition (low beams, black clothing, glare), whereas drivers recognized 100% of the pedestrians who wore retroreflective clothing configured to depict biological motion (no glare). In the absence of glare, mean recognition distances varied from 0.0 m (older drivers, low beam, black clothing) to 220 m (722 feet; younger drivers, high beam, retroreflective biomotion). These data provide new motivation to minimize interactions between vehicular and pedestrian traffic at night and suggest garment designs to maximize pedestrian conspicuity when these interactions are unavoidable.

  Title Spectral considerations for outdoor lighting: Designing for perceived scene brightness Type Journal Article
  Year 2014 Publication Lighting Research and Technology Abbreviated Journal Lighting Res. & Tech.  
  Volume 47 Issue 8 Pages (up) 909-919  
  Keywords Public Safety; outdoor lighting; photopic; photopic illuminance; human vision; metrics; task lighting; parking lots  
  Abstract Photopic illuminance is the photometric metric used today for specifying parking lot lighting levels. The photopic luminous efficiency function does not represent the spectral sensitivity of the perceived scene brightness of parking lots. Sources with a greater proportion of short-wavelength radiation will be seen as brighter for the same photopic illuminance. Moreover, the psychological benefit of providing people with a sense of safety and security in a parking lot is better correlated with the perceived brightness of the parking lot than with its photopic illuminance. Because photopic illuminance is not predictive of the psychological benefit expected from the parking lot lighting system, electric energy will be unnecessarily wasted if specifications are based upon this metric. Specifying parking lot lighting with a benefit metric based upon perceived scene brightness could reduce electric power requirements as well as the amount of radiant energy reflecting from the pavement and escaping into the night sky. A method of equating brightness for different spectral power distributions is provided.

  Title New Framework of Sustainable Indicators for Outdoor LED (Light Emitting Diodes) Lighting and SSL (Solid State Lighting) Type Journal Article
  Year 2015 Publication Sustainability Abbreviated Journal Sustainability  
  Volume 7 Issue 1 Pages (up) 1028-1063  
  Keywords Conservation; sustainable development; exterior; ecological; environmental; economic; impact; light pollution; safety; visibility; social  
  Abstract Light emitting diodes (LEDs) and SSL (solid state lighting) are relatively new light sources, but are already widely applied for outdoor lighting. Despite this, there is little available information allowing planners and designers to evaluate and weigh different sustainability aspects of LED/SSL lighting when making decisions. Based on a literature review, this paper proposes a framework of sustainability indicators and/or measures that can be used for a general evaluation or to highlight certain objectives or aspects of special interest when choosing LED/SSL lighting. LED/SSL lighting is reviewed from a conventional sustainable development perspective, i.e., covering the three dimensions, including ecological, economic and social sustainability. The new framework of sustainable indicators allow prioritization when choosing LED/SSL products and can thereby help ensure that short-term decisions on LED/SSL lighting systems are in line with long-term sustainability goals established in society. The new framework can also be a beneficial tool for planners, decision-makers, developers and lighting designers, or for consumers wishing to use LED/SSL lighting in a sustainable manner. Moreover, since some aspects of LED/SSL lighting have not yet been thoroughly studied or developed, some possible future indicators are suggested.
