  Title (up) A Novel Barricade Warning Light System Using Wireless Communications Type Journal Article
  Year 2018 Publication SAE Technical Paper 2018-01-5036 Abbreviated Journal  
  Volume In press Issue Pages  
  Keywords Lighting; Safety  
  Abstract Workers in construction and transportation sectors are at increased risk for work-related injuries and fatalities by nearby traffic. Barricade-mounted warning lights meeting current specifications do not always provide consistent and adequate visual guidance to drivers and can contribute to glare and reduced safety. Through an implementation of sensors and wireless communications, a novel, intelligent set of warning lights and a tablet-based interface were developed. The lights modulate between 100% and 10% of maximum intensity rather than between 100% and off in order to improve visual guidance and adjust their overall intensity based on ambient conditions. The lights can be synchronized or operated in sequential flash patterns at any frequency between 1 and 4 Hz, and sequential patterns automatically update based on global positioning satellite (GPS) locations displayed in the control interface. A successful field demonstration of the system verified that its functions were viewed favorably by transportation safety personnel.

  Title (up) A Novel Illuminance Control Strategy for Roadway Lighting Based on Greenshields Macroscopic Traffic Model Type Journal Article
  Year 2018 Publication IEEE Photonics Journal Abbreviated Journal IEEE Photonics J.  
  Volume 10 Issue 1 Pages 1-11  
  Keywords Lighting; Planning; Economics  
  Abstract Most street lights currently deployed have constant illumination levels or vary

based on a predetermined schedule. However, with advances in lighting controls, intelligent transportation systems, and the efforts of transportation agencies at regional and national levels to better sustain and manage the transportation system by monitoring the roadway network, many different types of real-time traffic data are available; which enables the implementation of a traffic responsive outdoor light system. The International Commission on Illumination (CIE) has proposed a class-based lighting control model based on a number of roadway parameters, some of which are traffic related. However, the adaptation of the available traffic data to the existing model is not obvious. In addition, the CIE model can be improved to better reflect traffic characteristics to increase energy efficiency of the overall street lighting system. The intention of this research is to quantify the relationship between real-time traffic, and roadway lighting and to develop a control strategy based on real-time traffic data in order to reduce light energy consumption, enhance safety, and maximize throughput of the roadway. Significant energy savings were observed when the proposed control strategy was implemented in two case studies using available lighting and traffic data for Washington, DC, and Montgomery County, MD, representing urban and rural roadway networks, respectively.

  Title (up) A Research on the Improvement of Visibility Using Low Deck Lighting in Bad Weather Type Journal Article
  Year 2020 Publication Journal of the Korean Institute of Electrical and Electronic Material Engineers Abbreviated Journal  
  Volume 33 Issue 3 Pages 186-193  
  Keywords Lighting  
  Abstract We investigate a fog-detection CCT control system using low deck lighting as a solution to the forward visibility of pole-type street lamps employed on existing roads. The lighting standards were met with a light source that has less compared with those of pole-type street lamps. The results show that the transmission rate was increased by changing the color temperature by automatically recognizing fog in bad weather and minimizing the phenomenon of lighting. In addition, it was allowed to create a safer and more comfortable driving environment for drivers owing to flicker or light pollution of existing pole-type street lamps. As a result, if lighting is used at a lower level than pole-type street lamps, the accident rate caused by securing the driver's forward visibility can be reduced sharply and existing problems can be resolved.
