Regional Strategic Transportation Safety Plan

What Is the Strategic Transportation Safety Plan (STSP)?

A regional transportation safety plan utilizes the results of crash data analysis and stakeholder/public input to identify proven strategies, actions, programs, and projects to reduce the prevalence of transportation-related fatalities and serious injuries. The purpose of the Central Arizona Governments' (CAG) Strategic Transportation Safety Plan (STSP), the process for developing the document, and how it relates to other safety initiatives in the state and region is described in Section 1.0.

Overview & Purpose

The development of the STSP is an important step toward reducing fatalities and serious injuries on public roadways in the CAG Transportation Planning Area. Fatalities and serious injuries in the region have fluctuated since 2005, but most of these incidents are predictable and preventable. The STSP provides CAG with a framework for reducing the personal and economic costs of crashes and enhancing livability and public health in the region. The Plan was developed by CAG, in coordination with:

  • The Arizona Department of Transportation (ADOT)
  • Local governments
  • Other transportation and safety stakeholders
  • Tribal representatives

This diverse set of stakeholders represents the four Es of transportation safety (Engineering, Enforcement, Education, and Emergency Medical Services (EMS)) to ensure the Plan addresses the different facets of safety. It identifies the most important transportation safety issues in the CAG Region, also called emphasis areas, and offers strategies to comprehensively address these issues.


State Departments of Transportation (DOTs) and Metropolitan Planning Organizations (MPOs) play the leading roles in transportation safety planning. However, to make the greatest impact, it is important to look beyond the traditional stakeholders. Other stakeholders who should be at the table include:

  • State, Local, and Tribal Transportation Agencies
  • Regional Planning Organizations
  • Emergency Medical Services
  • Local Law Enforcement
  • Transit Agencies
  • State Agencies responsible for:
    • Safety data collection and management
    • Law enforcement
    • Motor vehicle departments
  • Federal Agencies:
    • Federal Motor Carrier Safety Administration
    • Federal Transit Administration
    • Federal Highway Administration (FHWA)
    • National Highway Traffic Safety Administration (NHTSA)
  • National Organizations:
    • American Association of State Highway and Transportation Officials (AASHTO)
    • American Public Transit Association
    • Association of Metropolitan Planning Organizations
    • Institute of Transportation Engineers
    • National Association of Regional Councils
    • National Cooperative Highway Research Program
    • Transportation Research Board
  • Highway Safety Community:
    • AAA Foundation for Traffic Safety
    • Governors' Highway Safety Representatives
    • Operation Lifesaver


A Strategic Highway Safety Plan (SHSP) is a major component and requirement of the Highway Safety Improvement Program (HSIP) (23 United States Code (USC) Section 148). It is a statewide-coordinated safety plan that provides a comprehensive framework for reducing highway fatalities and serious injuries on all public roads. An SHSP identifies a State's key safety needs and guides investment decisions towards strategies and countermeasure with the most potential to save lives and prevent injuries.
