Prepare Phase

This phase starts with the formulation of a public involvement and coordination plan and ends with the preparation of the actual 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. A parallel effort involves early coordination and development of a plan to engage the public and community stakeholders throughout the planning process. 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.

 Agency Coordination Plan

 Public Involvement Plan​

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 their 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.

 The Approach (How you do it)

 Evaluation and Prioritization Criteria​

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.

 Plans and Policy Review

 Existing Conditions Inventory

 Existing Needs Determination

 Funding Review

 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.  

 Future Conditions Overview

 Future Capacity Determination

 Future Travel Demand Determination

 Future Deficiencies Determination

 Future Needs Determination​

The following information provides a detailed overview on how to develop, evaluate, and select multimodal transportation solutions.

 Developing and Evaluating Solutions Overview

 Developing Solutions

 Evaluating Proposed Solutions

 Selecting and Prioritizing Preferred Solutions


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 task is completed after the Step 5: Developing & Evaluating Solutions task and builds upon the preliminary funding review assessment prepared in the Existing Conditions analysis.

 Identifying Potential Funding Sources


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. The Transportation Planning Rule defined in Oregon Administrative Rule 660-012 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.
