Highway Safety Improvement Program
The Safe, Accountable, Flexible, and Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU) established the Highway Safety Improvement Program (HSIP) as a Federal Highway Administration (FHWA) “core” program with dedicated funding for infrastructure-related highway safety improvement projects. The requirements for this program were established in Section 148 of Title 23, United States Code.
The HSIP is intended to identify sites which exhibit a safety need and to implement safety improvement projects to reduce the number and severity of crashes at hazardous intersections or sections, which include any element on any public road. The overall goal of the HSIP is to reduce the number of fatal and life-threatening injury crashes that occur throughout the state. Typical project types include:
          • Intersection improvements (i.e. channelization, traffic signalization and modifications, or sight distance improvements)
          • Pavement and shoulder widening
          • Guardrail and barrier improvements
          • Installation of crash cushions
          • Modification of roadway alignment, signing, pavement marking, and delineation
          • Breakaway utility poles and sign supports
          • Pavement grooving and skid-resistant overlays
          • Shoulder rumble strips/stripes, and
          • Minor structure replacements or modifications
Each year, as a part of the HSIP, the Mississippi Department of Transportation (MDOT) required by Federal Law to develop a Transparency Report. This annual Transparency Report, known as the “5% Report”, describes no less than 5-percent of roadway locations exhibiting the most severe safety needs in Mississippi.
