Transportation System Plan

Maricopa County Department of Transportation (MCDOT) plans, designs, builds, maintains, and operates roadways within unincorporated Maricopa County. The Transportation System Plan (TSP) analyzes and tracks current and future needs for the MCDOT Roadway System.

Plan Updates


The TSP was last updated in 2007 (PDF). It is now being updated to project roadway improvement needs through the year 2035. The new TSP efforts account for population and employment growth and will identify potential roadway improvement needs on existing MCDOT owned and/or operated roadways.

Why a Transportation System Plan?


The MCDOT Roadway System currently makes up over 5,300 lane-miles of roadway.

Purpose


The purpose of the Transportation System Plan (TSP) is to plan for future transportation needs in Maricopa County which will support MCDOT in its mission to provide connections that improve people's lives throughout the County. The TSP includes goals, objectives, and strategies to help MCDOT plan for future travel demand.

Summary of Goals


The TSP goals, objectives, and strategies were shaped through five stakeholder workshops. The following is a summary of the goals, or you can view the complete document of goals, objectives, and strategies (PDF).

Primary TSP Goals Include:


  • Promote quality of life and economic vitality.
  • Provide a system that is safe and efficient for all modes of travel.
  • Encourage a seamless regional transportation network.
  • Protect past and future transportation investments through strategic system preservation.

What is the TSP?


The Maricopa County Department of Transportation (MCDOT) Transportation System Plan (TSP) is a long-range plan that establishes a framework for the current and future transportation needs of all Maricopa County residents. The TSP outlines a vision for the planning and construction of facilities on the MCDOT Roadway System.

MCDOT's current TSP was approved by the County Board of Supervisors in 2007. The 2007 TSP outlined a vision for the planning and construction of facilities through 2026. The current update to the TSP outlines a vision for the planning and construction of facilities through 2035.

Three Phases


There are three phases in the TSP 2035 process.

Phase 1: Research & Data Collection


Phase 1 is a regional planning-level evaluation and consists of gathering data on existing and planned transportation facilities, analyzing information and developing travel demand models and forecasts. This effort includes a Needs Analysis report, an Alternative Modes evaluation and the gathering of initial information for funding.

Phase 2: Plan Development


Phase 2 includes organizing information gathered during Phase I and developing a draft document for technical and public review and comment.

Phase 3: Plan Adoption


During the final phase of TSP 2035, the Draft TSP 2035 is submitted for review to and recommendation by the Transportation Advisory Board. This is followed by review and formal adoption by the Maricopa County Board of Supervisors.

All three phases are conducted in consultation with a Technical Advisory Committee (TAC) and a Stakeholder Advisory Committee (SAC) representing agency and constituency interests. The TAC/SAC assists in the identification and resolution of issues or differing requirements to build a broad-based consensus which guides the development of the TSP update.

The following is a list of information that will be contained within the TSP 2035. Additional information may be added during the TSP 2035 process.
