  • 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.
