Highway Safety Improvement Program (HSIP) - Secondary Program


Under the new Moving Ahead for Progress in the 21st Century (MAP-21) transportation bill, the Iowa Department of Transportation will receive more federal safety funding than in the past, but there is a key change to the Highway Safety Improvement Program (HSIP). The High Risk Rural Roads Program, which was an HSIP set-aside under the previous transportation bill, no longer exists.

Iowa DOT is collaborating with Iowa County Engineers Association to continue a safety program for the county road system under a new name, HSIP Secondary Program. The HSIP Secondary Program will provide a $2 million set-aside from the HSIP. The HSIP Secondary Program receives a 90 percent federal reimbursement, and a 10% local match is required; using matching funds from the Transportation Safety Improvement Program will result in a net zero funding requirement for the county.

This program will promote a greater number of projects on the Secondary Road System by focusing on low cost, systemic safety improvements. The key focus of the program would be to reduce lane departure crashes. The program will look for projects in the $10,000 per mile cost range. In addition, the program will promote systemic implementation of safety countermeasures. The systemic approach installs countermeasures along an entire corridor, in lieu of treating only a problem location. For example, a project could be developed to address curve crash issues on roadways of a certain classification or type. Systemic projects could include many miles across a county, and even include neighboring counties or multiple counties.
