PROVEN SAFETY COUNTERMEASURES FUNDING SCENARIO PACKAGE

Imagine your agency’s leadership gave you $100 million to improve safety in your community, jurisdiction, or State. How would you spend it? What combinations of improvements can you add to your system with that budget to maximize the reduction in fatalities and serious injuries? The Proven Safety Countermeasure (PSC) Investment Tool, Companion Guide, and Funding Scenario Briefing Templates provide high-level planning insights for safety engineers, planners, and program managers to estimate how investments into certain countermeasures will affect safety performance on the system.

  • The PSC Funding Scenario Tool is a spreadsheet that agencies can use to develop investment strategies for implementation of the FHWA PSCs.
  • The PSC Funding Scenario Companion Guide provides an explanation of the methodologies used for investment prioritization and explains how to use the PSC Funding Scenario too.
  • Agencies can update the Funding Scenario Briefing Templates with agency-specific estimates to serve as documentation, which can be shared with leadership and other stakeholders who may be involved in decision-making.
