The purpose of the North Carolina Highway Safety Improvement Program (HSIP) is to provide a continuous and systematic process that identifies reviews and addresses specific traffic safety concerns throughout the state. The program is structured in several distinct phases:
A system of safety warrants is developed to identify locations that are possibly deficient.
Locations that meet warrant criteria are categorized as potentially hazardous (PH) locations.
Detailed crash analyses are performed on the PH locations with the more severe and correctable crash patterns.
The Regional Traffic Engineering staff performs engineering field investigations.
The Regional Traffic Engineering staff utilizes Benefit: Cost studies and other tools to develop safety recommendations.
Depending on the cost and nature of the countermeasures, the investigations may result in requesting Division maintenance forces to make adjustments or repairs, developing Spot Safety projects, developing Hazard Elimination projects, making adjustments to current TIP project plans or utilizing other funding sources to initiate countermeasures.
Selected projects are evaluated to determine the effectiveness of countermeasures.
The ultimate goal of the HSIP is to reduce the number of traffic crashes, injuries and fatalities by reducing the potential for and the severity of these incidents on public roadways.
