Highway Safety Improvement Program (HSIP)

The HSIP mission is to identify and fund highway safety projects that maximize lives saved and injuries eliminated per dollar spent.


Under the HSIP, DOT&PF Traffic and Safety personnel annually identify high accident locations on Alaska roads, evaluate corrective measures, fund the most cost-effective ones, and evaluate their effectiveness after projects are completed.

There are many competing needs and influences that vie for DOT&PF project funding through other programs. In contrast, HSIP funds are intended to be targeted single-mindedly at life-saving and injury reduction.

  • See 23 CFR 924link exits this website for the regulatory basis for the HSIP

Alaska’s Highway Safety Improvement Program (HSIP) is a federally-mandated program managed by the Alaska Department of Transportation and Public Facilities (DOT&PF).  Its purpose is to reduce fatalities and serious injuries due to crashes on Alaskan roads.
