  Title (up) Artificial lighting triggers the presence of urban spiders and their webs on historical buildings Type Journal Article
  Year 2018 Publication Landscape and Urban Planning Abbreviated Journal Landscape and Urban Planning  
  Volume 180 Issue Pages 187-194  
  Keywords Animals; Lighting  
  Abstract Different spider species living in the urban environment spin their webs on building facades. Due to air pollution, web aggregations entrap dirt particles over time, assuming a brownish-greyish colouration and thus determining an aesthetic impact on buildings and street furniture. In Europe, the most common species causing such an aesthetic nuisance is Brigittea civica (Lucas) (Dictynidae). In spite of the socio-economical relevance of the problem, the ecological factors driving the proliferation of this species in the urban environment are poorly described and the effectiveness of potential cleaning activities has never been discussed in scientific literature. Over one year, we studied the environmental drivers of B. civica webs in the arcades of the historical down-town district of Turin (NW-Italy). We selected a number of sampling plots on arcade ceilings and we estimated the density of B. civica webs by means of digital image analysis. In parallel, we collected information on a number of potential explanatory variables driving the arcade colonization, namely artificial lighting at night, substrate temperature, distance from the main artificial light sources and distance from the river. Regression analysis showed that the coverage of spider webs increased significantly at plots with higher light intensity, with a major effect related to the presence of historical lampposts with incandescent lamps rather than halogen lamps. We also detected a seasonal variation in the web coverage, with significant higher values in summer. Stemming from our results, we are able to suggest good practices for the containment of this phenomenon.

  Title (up) Artificial night lighting affects dawn song, extra-pair siring success, and lay date in songbirds Type Journal Article
  Year 2010 Publication Current Biology : CB Abbreviated Journal Curr Biol  
  Volume 20 Issue 19 Pages 1735-1739  
  Keywords Animals; Environmental Pollution; Female; Light; *Lighting; Male; *Reproduction; Sexual Behavior, Animal/*physiology; Songbirds/*physiology; Time Factors; *Vocalization, Animal  
  Abstract Associated with a continued global increase in urbanization, anthropogenic light pollution is an important problem. However, our understanding of the ecological consequences of light pollution is limited. We investigated effects of artificial night lighting on dawn song in five common forest-breeding songbirds. In four species, males near street lights started singing significantly earlier at dawn than males elsewhere in the forest, and this effect was stronger in naturally earlier-singing species. We compared reproductive behavior of blue tits breeding in edge territories with and without street lights to that of blue tits breeding in central territories over a 7 year period. Under the influence of street lights, females started egg laying on average 1.5 days earlier. Males occupying edge territories with street lights were twice as successful in obtaining extra-pair mates than their close neighbors or than males occupying central forest territories. Artificial night lighting affected both age classes but had a stronger effect on yearling males. Our findings indicate that light pollution has substantial effects on the timing of reproductive behavior and on individual mating patterns. It may have important evolutionary consequences by changing the information embedded in previously reliable quality-indicator traits.

  Title (up) Assessing Public Perceptions about Road Lighting in five Neighborhoods of Tirana, Albania Type Journal Article
  Year 2019 Publication Abbreviated Journal  
  Volume Issue Pages  
  Keywords Public Safety; Psychology; Roadway lighting; Albania; Europe  
  Abstract Lighting is essential for sight, human health and well-being, emerging the need for assessing exterior lighting to better understand how far public is satisfied about exterior lighting. Exterior lighting was assessed in five major roads of the capital city of Tirana, Albania, in November 2017. Security, obstacle detection and visibility were evaluated using questionnaires for road lighting. The approximately 87 and 60 percent of respondents, respectively, were not able to detect a pavement obstacle after-dark and to distinguish a

familiar face at a distance of 5 m and 10 m along roads. Road lighting after-dark was unsatisfactory to 60 percent of respondents. These findings identified road lighting could be inadequate for users, requiring further investigation and new data collection of road lighting in neighborhoods of Tirana.

  Title (up) Assessment of an Adaptive Driving Beam Headlighting System: Visibility and Glare Type Journal Article
  Year 2016 Publication Transportation Research Record: Journal of the Transportation Research Board Abbreviated Journal Transportation Research Record: Journal of the Transportation Research Board  
  Volume 2555 Issue Pages 81-85  
  Keywords Lighting  
  Abstract Recent developments in solid-state lighting, sensor, and control technologies make new configurations for vehicle forward lighting feasible. Adaptive driving beam (ADB) systems build on systems that automatically switch from high- to low-beam headlights in the presence of oncoming vehicles. ADB systems can detect oncoming headlights and preceding taillights and reduce their intensity only in the direction of the other lights, while they maintain higher levels of illumination throughout the remainder of the field of view. The nominal benefit of ADB systems is the provision of high-beam levels of illumination in the forward scene, while glare is reduced to oncoming and preceding drivers, who perceive low-beam illumination levels. In this study, two dynamic field experiments were conducted: one experiment measured the ability of observers to identify the walking direction of roadside pedestrian targets with and without the use of the ADB system; the other experiment evaluated the discomfort glare elicited by the ADB system compared with the glare from conventional low- and high-beam headlights. The findings from both experiments were consistent with previous analytical and static field tests and suggested that ADB systems can offer safety benefits beyond those offered by conventional headlight systems.

  Title (up) Assessment of Light Pollution Based on the Analysis of Luminous Flux Distribution in Sports Facilities Type Journal Article
  Year 2019 Publication Engineer of the XXI Century Abbreviated Journal  
  Volume 70 Issue Pages 139-150  
  Keywords Lighting  
  Abstract The article attempts to assess the amount of light pollution with artificial light from sports facilities. The football stadium has been analysed, while considering a few configurations that take into account different coefficients of reflection of the luminous flux for the tribunes and the object main board. Simplified model of the football stadium was introduced to the DIALux simulation software, and then computer calculations were made for selected variants. In addition, the applicable normative requirements in the field of lighting systems were discussed and the mathematical distribution of the luminous flux in the examined sports facility was presented.
