South Carolina (SC) experiences high levels of pedestrian crashes and it was found that 80 percent of these crashes happened at night for the years 2007- 2016 due to the lack of illumination at crash locations. The objectives of this study were twofold: (i) characterize pedestrian nighttime crashes using the available database and provide short-term implementation solutions and (ii) to conduct a pilot test for comparing the effectiveness of camera technologies that can detect pedestrians under low light. Several data sources were used to understand the qualitative and quantitative aspects of pedestrian crashes, including the South Carolina Department of Transportation Crash Database, Crash Report Forms, Roadway Inventory Management Systems (RIMS) Database, and additional data extracted from online mapping tools. Midblock crashes were the focus of this study. The pilot test was to gauge the efficacies of two types of camera technologies – 1) Pan-tilt-zoom (PTZ) camera with night vision capabilities and 2) fixed focus thermal IP camera under four test conditions. The tested conditions included the following scenarios:

  • Dark not lit
    • Pedestrian detection with night vision camera in a dark not lit section
    • Pedestrian detection with infrared camera in a dark not lit section
  • Dark Lit 
    • Pedestrian detection with night vision camera in a dark section lit with vehicle light
    • Pedestrian detection with infrared camera in a dark section lit with vehicle light 

The tests were conducted at a roadway section where there were no streetlights. As pedestrian detection is relevant for a transportation system that consists of automated vehicles, there is great value in exploring opportunities to integrate technology that enhances driver and pedestrian capability and visibility.
