Search the Noteworthy Practices database Minnesota Makes Systemic Safety Improvements Based on Risk Assessments at County LevelOriginal publication: FHWA Safety Program | Practice - Minnesota (PDF, 426kB)Publication Year: 2011Overview of PracticeMinnesota DOT (Mn/DOT) is another example of a state implementing a systemic approach. While Missouri's approach is focused on state-maintained roadways, Minnesota has taken a different approach through the development of safety plans for each of state's 87 counties. The safety plans disaggregate the severe crash types by each of the AASHTO SHSP emphasis areas to identify emphasis and target crash types at the regional level. Mn/DOT has selected crash surrogates for various facility types to use in the risk assessment. Locations identified and included in the plans can be submitted for project funding through the HSIP. ResultsOne example is a risk assessment based on curve radius. Evaluating the data against surrogate risk factors helped Minnesota identify curves with 500-1,200 foot radii to consider for systemic improvements. ContactBradley Estochen Publication Year: 2011 |
