• Abstract:
  This report documents the findings of a two-year study that investigated the potential benefits of wider
  
  edge line pavement markings. There were four general tasks discussed in the report: 1) review of literature,
  
  2) survey of the state of the practice, 3) summary of recent safety analyses, and 4) a human factors nighttime
  
  study of the impact of wider and brighter edge line pavement markings. The results show that states are
  
  increasing their use of wider edge lines, and safety studies are beginning to show evidence supporting the use
  
  of wider edge lines for two-lane highways. The human factors study included surrogate safety measures,
  
  such as lateral placement, edge line encroachments, and driver eye glance patterns. The results from these
  
  metrics all support positive safety findings. Pavement marking brightness had less of an impact than
  
  pavement marking width on these operational metrics. In this study, there was no attempt to relate pavement
  
  marking retroreflectivity to safety. The researchers recommend the use of wider pavement markings on twolane
  
  highways with additional experimentation to verify the benefits described in this report.
