• Abstract:
  The research team reviewed past practices for barrier delineation and evaluated barrier striping at several locations in Texas. Five existing sites with barrier striping were analyzed using crash data. In addition, striping was installed at a high-crash location for before-and-after evaluation. The study considered crash history, roadway and traffic characteristics, weather and lighting conditions, and probe vehicle speed data. Statistical approaches included crash frequency models and survival analysis. Speed data from a San Antonio site (I-10 near I-410) were also examined. Based on the analyses, the team recommended refinements to TxDOT’s draft special specification, including material details, spacing, and installation practices.
