• Abstract:
  This case study demonstrates the application of the Systemic Safety Project Selection Tool by the Missouri Department of Transportation. The MoDOT evaluated the effects of adding edge line pavement markings to 570 miles of rural, two-lane State highways with average daily traffic volumes between 400 and 1000 vehicles. MoDOT completed a “before vs. after” evaluation of edge lines using a customized spreadsheet that incorporates Empirical Bayes methodology to estimate the effectiveness of the implemented countermeasure. Crash data collected after the project provided proof that implementing low-cost countermeasures on low-volume roads with low-crash frequency and density yields a reduction in crashes.
