Title Comparison of the onset of dawn chorus of bulbuls and house sparrows in two different geographical locations: effect of climate, noise and light pollution. Type Journal Article
Year 2011 Publication Research Opinions in Animal & Veterinary Sciences Abbreviated Journal (up)
Volume 1 Issue 4 Pages 220-225
Keywords Animals; bulbul; Pycnonotidae; house sparrow; Passer domesticus; Tulkarem; Ar-Rayyan; Palestinian Authority; Riyadh; Saudi Arabia; dawn chorus; urbanization
Abstract The onset of dawn chorus was studied for a period of fourteen months for bulbuls (Pycnonotidae) and house sparrows (Passer domesticus) in two different geographical locations. One is very quiet and semi lit place in the suburbs of the small Mediterranean city of Tulkarem/Palestinian Authority. The other location is comparatively noisy and very well lit place in the Ar-Rayyan urban district of the city of Riyadh/ Saudi Arabia where desert climate prevails. This study is the first of its kind and clearly shows that the timing of dawn chorus is similar for

autumn and winter seasons in both locations but major differences were observed from February until September between the two locations. It can be concluded that very early timing of dawn chorus during spring / summer for the Riyadh location cannot only be attributed to breeding season and is temperature dependent (strong positive correlation, r>0.6). The similarities for autumn and early winter between the two locations is very interesting in that it is not in agreement with the notion that big cities (urbanization) influence the timing of dawn chorus due to noise and light pollution. This emphasizes that dawn chorus is a complex process and that change in the onset and pattern of dawn chorus can not merely be attributed to one variable such as noise or light pollution alone.

Title THE RELATIONSHIP BETWEEN ROAD LIGHTING QUALITY AND ACCIDENT FREQUENCY – TRRL LABORATORY REPORT 929. Type Journal Article
Year 1980 Publication Abbreviated Journal (up)
Volume Issue Pages
Keywords Lighting; quality; accident rate; accident; frequency; luminance; glare; uniformity; urban area; daylight; darkness; surfacing; pedestrian
Abstract many studies have related changes in accident frequency to the presence of street lighting, and a few have examined its variation over a range of lighting quality, as measured by illuminance. this investigation attempts to find which of several measures of lighting (describing quantity – as represented by luminance or illuminance – uniformity and glare) most clearly explain variations in accident frequency. about 100 lit sites, almost all in built-up areas, were measured for lighting quality in dry-road conditions. the lighting variables measured were related to the dark:day ratios of accident frequency for the same sites. the strongest relationship found was that for average road surface luminance: in the range 0.5-2.0 candelas/m2, it is estimated that an increase of 1 cd/m2 is associated with a 35 per cent lower accident ratio. other measures of luminance and illuminance were also found to be related to accident ratio (and to each other), but not as clearly as was average road luminance, which is therefore the preferred explanatory variable. analysis of pedestrian and non-pedestrian accidents separately did not reveal a relationship between the former and lighting quality. in contrast, non-pedestrian accidents showed similar relationships to those for all accidents, with the addition of a possible relationship with overall uniformity of luminance.(a)
