Title Pollution-Free Road Lighting Type Journal Article
Year 2001 Publication Transactions of the International Astronomical Union Abbreviated Journal (down) Trans. Int. Astron. Union
Volume 24 Issue 03 Pages 364
Keywords Lighting; Skyglow
Abstract The beneficial effects of road lighting are often seen as very important. They relate to reducing road accidents and some forms of crime but also enhance the social safety of residents and pedestrians and the amenity for residents. Road traffic in developing countries is much more hazardous than in industrialized countries. Accident rates in ‘low’ income countries may be as much as 35 times higher than in ‘high’ income countries. Thus, it might be much more cost-effective to light roads in the developing world than in the industrialized world. Fighting light pollution is more pressing in developing countries as most of the major high-class astronomical observatories are there. Astronomical observations are disturbed by light from outdoor lighting installations, part of which is scattered in the atmosphere to form ‘sky glow’. The International Lighting Commission CIE has published a Technical Report giving general guidance for lighting designers and policy makers on the reduction of the sky glow.

Title Effects of road lighting on motorways Type Journal Article
Year 2009 Publication Traffic Injury Prevention Abbreviated Journal (down) Traffic Inj Prev
Volume 10 Issue 3 Pages 279-289
Keywords Lighting; Public Safety; Security
Abstract OBJECTIVES: The study has three objectives. The first is to investigate how the effect of road lighting on motorway accidents varies with different weather and road surface conditions. The second is to evaluate the future benefit of road lighting as a safety measure on motorways. The third is to evaluate the need for further research in the field of motorway lighting. METHOD: This article presents a cross-sectional study of the effects of road lighting on motorways mainly in The Netherlands. The main source of data is a Dutch database of accidents covering the period 1987-2006, but British and Swedish data are also used. RESULTS: The effect of road lighting on motorways is found to be greater in The Netherlands than in Great Britain or Sweden. Reasons for this are not known. Effects are found to vary according to background characteristics and are lesser during precipitation than during fine weather and on wet road surfaces than on dry surfaces. No effect of road lighting is found during fog. Collision with light poles constitutes a large number of accidents on lit motorways and reduces the safety effect of road lighting. CONCLUSIONS: The effect of road lighting on injury accidents during darkness is found to be very high (-49%) on Dutch motorways. However, the effect seems to vary between countries. Collisions with light poles reduce the effect of road lighting. Road lighting will probably be an effective safety measures on motorways for many years. In the long term, however, the benefit of road lighting will probably be reduced along with the implementation of new vehicle and road technology. Modern technology permits a continuous adaptation of luminance levels to optimize the effect of road lighting on safety while at the same time minimizing energy consumption. However, more detailed knowledge concerning the effects of road lighting at different lighting levels is needed in order to use this technology effectively. Alternative or additional measures like LED guide lights and light road surfaces also need to be evaluated.

Title Blocking harmful blue light while preserving image color appearance Type Journal Article
Year 2016 Publication ACM Transactions on Graphics Abbreviated Journal (down) Tog
Volume 35 Issue 6 Pages 1-10
Keywords Lighting; Vision
Abstract Recent study in vision science has shown that blue light in a certain frequency band affects human circadian rhythm and impairs our health. Although applying a light blocker to an image display can block the harmful blue light, it inevitably makes an image look like an aged photo. In this paper, we show that it is possible to reduce harmful blue light while preserving the blue appearance of an image. Moreover, we optimize the spectral transmittance profile of blue light blocker based on psychophysical data and develop a color compensation algorithm to minimize color distortion. A prototype using notch filters is built as a proof of concept.

Title Common Poorwill activity and calling behavior in relation to moonlight and predation Type Journal Article
Year 2008 Publication The Wilson Journal of Ornithology Abbreviated Journal (down) The Wilson Journal of Ornithology
Volume 120 Issue 3 Pages 505-512
Keywords birds; poorwills; Common Poorwill; Phalaenoptilus nuttallii; Arizona; moonlight
Abstract We investigated the influence of lunar and environmental factors on behavior of Common Poorwills (Phalaenoptilus nuttallii) in southern Arizona under a diverse set of natural and artificial conditions. Radio-marked poorwills were most active shortly after sunset during the new moon. Movements declined as evening progressed. Activity remained high for several hours after sunset when the moon was full. Poorwills were heard calling from March through October, but most calling occurred between early May and September. Only ambient light was correlated with number of poorwills heard calling. More poorwills responded to playbacks of conspecifics when the moon was full than when it was new. Poorwills did not change their response to conspecifics during full moon when playback of poorwill calls followed playback of Great Horned Owl (Bubo virginianus) calls but, during the new moon, fewer birds responded following the owl call. Poorwill behavior is strongly influenced by lunar conditions; their ability to detect and evade predators is important when calling advertises their location.
