Statewide Implementation of Safety Analysis and Visualization Processes in Identifying Highway Safety

Research project 0-6912, Innovative Tools and Techniques in Identifying Highway Safety Improvement Projects (HSIP), developed a framework that encompasses innovative visualization processes and nationally evolving safety assessment procedures recommended by American Association of State Highway and Transportation Officials’ (AASHTO) Highway Safety Manual (HSM) and the Receiving Agency’s Roadway Safety Design Workbook. The goal of these empirically-based, statistical, data-driven procedures is to identify sites that have the highest potential to realize a reduction in crash frequency by implementing appropriate countermeasures. The combined use of visualization products and data-driven safety analysis have yielded several benefits not only for those Receiving Agency Districts that used them, but also for other state and local transportation agencies that have implemented similar procedures. This implementation project shall update, refine, and implement both a) the Crash Analysis and ViSualization (CAVS) process, and b) the network screening process.
