Description
Wisconsin’s Highway Safety Improvement Program (HSIP) is a core Federal-aid program administered by the Wisconsin Department of Transportation (WisDOT). It supports infrastructure improvements on all public roads, including non-State-owned roads and roads on Tribal lands. Projects address documented crash problems through a strategic, data-driven approach, with lower-cost treatments given first consideration.
The program emphasizes improvements that can be implemented quickly, ideally within four years. Examples include intersection improvements, traffic signals, sight-distance improvements, auxiliary lanes, traffic calming, roadside barriers, and pedestrian, bicycle, and disability-related safety improvements where crashes occur. HSIP includes the High Risk Rural Roads Program (HRRRP), which focuses on low-cost treatments addressing run-off-the-road, fatal, and serious-injury crashes on rural collector corridors. Regional Safety Engineers help applicants identify countermeasures and develop applications.
