Prepare Phase

This phase starts with the formulation of a public involvement and coordination plan and ends with the preparation of the TSP document. The steps in between relate to information gathering and analysis needed to develop elements of the TSP.

A key step in the development or update of a TSP is early coordination and formation of various agency advisory committees. These committees can be instrumental in supporting and guiding the technical aspects of the transportation planning process. This effort involves early coordination and development of a plan to engage the public and other interested parties throughout the planning process, including addressing Title VI and integrating equitable engagement. This plan will define the means and methods by which Statewide Goal 1: Public Involvement will be met in developing the TSP. This section provides guidance on agency coordination and development of a formal public-involvement plan. In addition, cities and counties in metropolitan areas and Metro may be required to meet additional requirements related to equity analysis. Guidance for equity analysis is also provided in this section.

 Equity Analysis​​​

One of the initial steps in the development of a TSP is to identify and validate the goals and objectives that support the desires and vision the community has for the existing and future transportation system. The following information expands upon the importance of goals and objectives in the planning process and provides guidance on their development. Guidance concludes with various samples that can serve as starting points for future TSPs. In addition, cities and counties in metropolitan areas and Metro are required to meet additional requirements related to performance tracking and setting performance standards, which is discussed in this section.

An early step in the development of a TSP is a review of the plans and policies that currently influence and shape the transportation infrastructure. This is followed by a thorough inventory and assessment of the existing multimodal transportation network. The following information provides a detailed overview of the various local, regional, and state planning documents that are typically reviewed in the development of a TSP. Detailed guidance is then provided on the inventory, assessment, and documentation of the existing transportation infrastructure. As part of understanding existing conditions, a funding review is also completed during this step in the development of a TSP.​

 Documentation of Existing Conditions and Needs​

Following the Existing Conditions assessment, the next step in the planning process is to analyze future multimodal travel demand and identify future needs (deficiencies and gaps) in the transportation infrastructure. The following information provides a detailed overview of the requirements and processes needed to prepare the Future Conditions assessment.​

 Documentation​

The transportation funding program identifies which projects/programs developed in the TSP process will be funded based on existing and anticipated revenue sources as well as the projected costs of proposed projects and programs. This step is completed after and builds upon the preliminary prepared in Step 3: Existing Conditions.​

 Identifying Potential Funding Sources

 Documentation​

The TSP document is the culmination of the planning process. It identifies the goals and objectives of the TSP update and the new policies, plans, programs, and projects that will shape the transportation system over the planning horizon. Oregon Administrative Rule 660-012, also known as the Transportation Planning Rule, outlines specific required content for all TSPs. The following sections outline these requirements while providing guidance and best practices on additional content, organizational format, and presentation.
