    • Abstract:
      This case study presents a safety analysis conducted by the Wisconsin Department of Transportation (WisDOT) at the intersection of State Highway 75 (WIS 75) and Plank Road (County Road A) in Racine County, WI. WisDOT proactively identified key safety needs early in the project development process and used a data-driven approach to evaluate the safety effects of potential alternatives. The corridor is scheduled for resurfacing in 2023, and through the network screening process, WisDOT identified an opportunity to develop a Highway Safety Improvement Program-related project in conjunction with routine maintenance. WisDOT’s diagnosis process reviewed recent crash history for potential contributing factors (e.g., driver behavior, sight distance, curvature, intersection geometry, etc.) and underscored the need to reduce failure-to-yield crashes. A preliminary intersection control evaluation eliminated infeasible alternatives early in the process and highlighted appropriate alternatives for further analysis. WisDOT applied State-calibrated safety performance functions in the Interactive Highway Safety Design Model software to predict crashes for each alternative and used State-approved crash modification factors where applicable. With these results, the economic appraisal step highlighted the most cost-effective alternative for this particular location. The State of the Practice methods and tools applied at each step in the process allowed WisDOT to thoroughly evaluate a safety need on its public road network as part of an institutional and readily repeatable planning process.
