Contributing Factors for Focus Crash Types and Facility Types


This presentation describes efforts to identify focus crash types, focus facility types, and associated crash contributing factors to inform applications of systemic safety improvements. Systemic safety improvements—when selected and targeted appropriately—provide an opportunity to proactively reduce crashes. The objectives of this research are to (1) select reliable and applicable data resources, statistical methodologies, analysis procedures, and tools, (2) conduct data analysis to identify and validate focus crash types and facility types and their contributing factors, and (3) identify potential low-cost safety strategies that may effectively be used as systemic safety improvements. HSIS data from WA, CA, and OH, were used.
