    About this Project
    Brief Project Description & Background
    The focus of this project is the identification and evaluation of one or two of these proactive systemic tools or methodologies. Several of these exist in various levels of development and they each require a different amount of data for their application. Of particular interest is the methodology being used to develop the county safety plans in Minnesota.
    Research Objective
    The first objective of this project is to evaluate the impact on the prioritization results of changes in the weighting of the characteristics or factors considered in one or more proactive systemic safety improvement tools or methodologies
    Potential Benefits
    The results from this research project should increase the understanding of the identification and prioritization results produced by proactive systemic safety improvement methodologies and improve the tools available to state and local agencies when considered rural roadway safety improvements. The impact should be more efficient and effective safety improvement implementation along rural low volume roadways.
    Abstract
    More than half of the crash fatalities in the United States occur along rural roadways. A reduction in these events is necessary, but their widespread nature requires the application of a project identification and prioritization methodology that is different than the traditional reactive "hot spot" approach. Proactive systemic safetyimprovement methodologies and tools use crash data and roadway characteristics to approximate risk and identify/prioritize potential safety improvement locations. There are currently several proactive systemic safety improvement alternatives in various
