A Strategic Traffic Safety Plan (STSP) is a statewide, coordinated plan that provides a comprehensive framework for reducing fatalities and serious injuries on all public roads. The STSP is developed by the Arizona Department of Transportation in cooperation with local, regional, state, federal, tribal, non-profit and private-sector safety stakeholders. The STSP is a data-driven, multiyear plan that establishes statewide goals and objectives and identifies Emphasis Areas that must be addressed to reduce traffic fatalities and serious injuries. The plan outlines feasible strategies and action steps or countermeasures to address the Emphasis Areas through integration of the 4 E’s of transportation safety: Engineering, Education, Enforcement and Emergency Medical Services.
