Strategic Highway Safety Plan (SHSP)

The Strategic Highway Safety Plan (SHSP) is a federally required statewide, comprehensive safety plan that provides a coordinated framework around which safety stakeholders can unite to reduce highway fatalities and serious injuries on all public roads. The Indiana’s SHSP is data-driven and establishes the goals, objectives, and strategies to advance the vision of zero fatalities and serious injuries.

Indiana’s Strategic Highway Safety Plan, as required by title 23 U.S.C. § 148, identifies critical highway safety problems and opportunities for saving lives, reducing suffering, and economic losses resulting from traffic crashes. It also serves to coordinate the traffic safety activities of state agencies, municipal entities and private highway safety organizations. Indiana continually evaluates and periodically revises the SHSP.

The SHSP documents coordination of purpose, common data sources, cooperative problem identification, emphasis areas, and partnerships. The lead state agencies evaluate implementation action plans annually as part of federally required highway safety action plans and reports.

  • Highway Safety Improvement Program (Per 23 CFR 924)
  • Highway-Rail Grade Crossing Safety Action Plan (Per 49 U.S.C. § 202)
  • Highway Safety Plan (Per 23 U.S.C. § 402)
  • Commercial Vehicle Safety Plan (Per 49 CFR 350)

As called for by the Infrastructure Investment and Jobs Act (IIJA), Indiana’s Vulnerable Road User (VRU) assessment examines the safety challenges faced by road users categorized as vulnerable, such as bicyclists, pedestrians, micromobility users, and other users of non-motorized vehicles (i.e., horse drawn conveyance).

HSIP Eligible Systemic Improvements

Nationwide research along with Indiana experience has shown that overall numbers of crashes with serious injury and fatal outcomes can be reduced by implementing proactive improvements to prevent crashes and to mitigate the severity when crashes do occur. The following list of HSIP Eligible Systemic Improvements contains safety improvement types that typically have a reasonably low unit cost and may be deployed at multiple locations in a single construction project.  These safety improvement types may also improve traffic movement, reliability and safe access for non-motorized road users.
