The Highway Safety Improvement Program (HSIP) is a core Federal-aid program with an objective to achieve a significant reduction in traffic fatalities and serious injuries on all public roads, including non-State-owned roads and roads on Tribal lands. The HSIP requires a data-driven and strategic approach to fund highway safety projects at sites that have experienced a high crash history. The program has an emphasis on low-cost projects that can be implemented quickly, ideally within four years.
The HSIP funds projects that promote the reduction of traffic fatalities and serious injuries. Projects are solicited from or requested by Local Public Agencies (LPA’s), County Traffic Commissions (TSC’s), County Highway Commissioners, and Metropolitan Planning Organizations (MPO’s). The federal funding ratio for HSIP funds is usually 90%, requiring a 10% match of state and/or local funds. To aid in identifying safety project locations, a link to Community Maps is provided below. Community Maps provides a statewide map of all police reported motor vehicle crashes from 2010 to the current year.
The Wisconsin Department of Transportation (WisDOT) accepts completed HSIP applications on a biannual basis. The mid-cycle application review process will begin after the February 15, 2025, deadline. The standard cycle application review process will begin after the August 15, 2025, deadline. Applications should be submitted to the appropriate WisDOT Regional HSIP Coordinator. HSIP Coordinators are also available to help answer any questions applicants may have about the HSIP or the application process. Regional Safety Engineers are available to assist in the development of HSIP applications and the identification of appropriate countermeasures at sites with safety concerns. The HSIP project application form (DT 1501) is available for download below. Additional information regarding the HSIP, High-Risk Rural Road Program (HRRRP), and Rail-Highway Crossing Program (RHCP) is available for download below.
