Title Bad Science: comments on the paper ‘Quantifying the impact of road lighting on road safety — a New zealand Study’ by Jackett & Frith (2013). Type Journal Article
Year 2020 Publication World Transport Policy and Practice Abbreviated Journal World Transp Policy & Practice
Volume 26 Issue (up) 2 Pages 10-20
Keywords Safety; Security; Commentary; Statistics; Collisions
Abstract The paper of Jackett & Frith (2013), which purports to show considerable gains for road safety with increasing road luminance, is seriously flawed. It asserts that increasing the luminance on roads causes improvements in road safety. Its cross-sectional design fails to rule out major potential confounders. using a longitudinal design would be a far superior approach. The paper exhibits poor statistical practice. The selection process for the relatively small sample of urban roads is unclear and the post hoc processing of the data is questionable. The analysis is seriously deficient, as variables which indicate detrimental effects of increased road lighting are removed from the modelling without proper justification and other variables are not included in the first analysis yet appear in the subsequent cosmetic analyses. The latter give an illusion of false certainty. The data collected, which would allow checking, is not published. The practice of the journal in which the paper appeared is seriously deficient in not allowing the publication of critical responses. although being used to promote increased road lighting, the paper’s claim disagrees with results from better quality research

Title Unawareness in environmental protection: The case of light pollution from traffic Type Journal Article
Year 2012 Publication Land Use Policy Abbreviated Journal Land Use Policy
Volume 29 Issue (up) 3 Pages 598-604
Keywords Public Safety; public policy; traffic safety
Abstract New information is often emphasized as a basis of effective and scientifically sound environmental policy and management. However, outdated or incorrect information is not automatically nor instantly replaced by new insights. This article focuses on the various ways environmental information can be unintentionally left with insufficient attention or purposefully neglected. Energy-related emissions caused by road traffic in Finland are used as an illustrative example and light pollution caused by artificial lighting is identified as an emerging issue that has gained especially low recognition in the environmental agenda. Four different reasons for this lack of recognition are discussed: recognized unawareness, false awareness, deliberate unawareness and concealed awareness. Paying attention to light pollution is important because of various ecological, socio-cultural and economic effects but also because implementing measures aimed for reducing light pollution create possibilities for alleviating other social and environmental problems in transport and land use policies.

Title Subjective impressions under LED and metal halide lighting Type Journal Article
Year 2014 Publication Lighting Research and Technology Abbreviated Journal Lighting Research and Technology
Volume 46 Issue (up) 3 Pages 293-307
Keywords lighting; outdoor lighting; subjective; LED; metal halide; *Safety; Belgrade
Abstract In order to compare subjective impressions created by LED and metal halide ambient lighting, a pilot project was conducted in a Belgrade park. All general requirements for an adequate comparison of subjective impressions were fulfilled. The survey was conducted using a questionnaire related to all aspects the researchers considered relevant for subjective evaluation of illuminated pedestrian paths in parks. It was concluded that the respondents, both those who had and those who did not have previous knowledge in the field of lighting, strongly preferred the use of metal halide lamps for the illumination of parks, which is in opposition to the statements of some LED manufacturers. It was also shown that light level and feelings of safety and comfort are evaluated as most important.

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 (up) 3 Pages 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.
