  Title Investigation of flashing and intensity characteristics for vehicle-mounted warning beacons Type Journal Article
  Year 2018 Publication Accident Analysis & Prevention Abbreviated Journal Accident Analysis & Prevention  
  Volume 119 Issue Pages 23-28  
  Keywords Security; Public Safety; Lighting  
  Abstract Reducing the potential for crashes involving front line service workers and passing vehicles is important for increasing worker safety in work zones and similar locations. Flashing yellow warning beacons are often used to protect, delineate, and provide visual information to drivers within and approaching work zones. A nighttime field study using simulated workers, with and without reflective vests, present outside trucks was conducted to evaluate the effects of different warning beacon intensities and flash frequencies. Interactions between intensity and flash frequency were also analyzed. This study determined that intensitiesof 25/2.5 cd and 150/15 cd (peak/trough intensity) provided the farthest detection distances of the simulated worker. Mean detection distances in response to a flash frequency of 1 Hz were not statistically different from those in response to 4 Hz flashing. Simulated workers wearing reflective vests were seen the farthest distances away from the trucks for all combinations of intensity and flash frequency.

  Title Adaptive Mechanism for Smart Street Lighting System Type Journal Article
  Year 2019 Publication Smart Intelligent Computing and Applications Abbreviated Journal  
  Volume 160 Issue Pages 69-76  
  Keywords Lighting  
  Abstract The adaptive street light has the ability to adapt to the motion of cycles, cars and pedestrians. It uses motion as well as light sensors to detect the traffic and light around. It dims when there is no movement on the road, and is brightened when there is any activity. Smart street lights are very dissimilar from the old methods of lighting. It is an automated system that will be able to automate the streets. The main objective of these lights is to decrease the utilization of power, while no activity is detected on the street. It will be switched ON while there are pedestrians and cars on the street or else they will get dimmed to 20% of the brightness. The proposed approach gives a method to conserve power by using the PIR sensors to sense the incoming traffic and hence turning ON a cluster of lights surrounding the traffic. As the traffic is passing by, the street lights left behind will dim on its own. Hence, a lot of power can be conserved. Also, during the day time when there is no need of light the LDR sensor will sense the light and the light will remain switched OFF. This smart street light system comes under the domain of smart city.

  Title 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.

  Title What Happens in the Shadows: Streetlights and How They Relate To Crime Type Journal Article
  Year 2017 Publication Abbreviated Journal  
  Volume Issue Pages  
  Keywords Crime; Lighting  
  Abstract After finding in a previous report, “Streetlights in the City: Understanding the Distribution of Houston Streetlights,” that the city of Houston’s more than 173,000 streetlights were not evenly distributed throughout the city, this next report answers the question: do places with more streetlights have lower crime rates?

The findings complicate the common perception that more streetlights lead to fewer crimes. While there was some evidence that a particularly high density of streetlights can provide protective benefits, excluding those extremes provides a much muddier picture, suggesting that crime is a reflection of other neighborhood contexts. As such, cities should be cautious in expecting direct reductions in crime with the introduction of more streetlights.
