Step 5: Solution Development & Evaluation

Developing Solutions

Oregon Administrative Rule (OAR) 660-012-0035 defines the requirements for the evaluation and selection of transportation system alternatives (referred to in this guidance as solutions) in non-metropolitan areas. As noted, "the TSP shall be based upon evaluation of potential impacts of system alternatives (or solutions) that can reasonably be expected to meet the identified transportation needs in a safe manner and at a reasonable cost with available technology." Per OAR 660-012-0035, the following components are to be evaluated as part of the system of solutions:

  • Improvements to existing facilities or services
  • New facilities and services, including different modes or combinations of modes that could reasonably meet identified transportation needs
  • Transportation System Management measures
  • Transportation Demand Management measures
  • A no-build system alternative

From a modal perspective, the types of solutions that will need to be considered as part of the development or update of a TSP are summarized in the following sections. The solutions for non-metropolitan areas are primarily based on best practices, while the solutions for metropolitan areas are based on guidance in OAR 660-012-0510, -0610, -0710, -0810, and others. It is important to ensure that these solutions are consistent with the purpose, goals, objectives, performance measures and targets established earlier in the planning process. OAR 660-012-0100 (8) requires cities and counties in metropolitan areas to design their transportation system plans to achieve the performance targets on progress toward meeting OAR Division 12 and Division 44 requirements. Solutions should be developed to meet the identified community’s transportation needs and to advance community goals such as safety, equity, and community health. Solutions should also include opportunities to improve the efficiency of the existing transportation system through strategies such as Transportation System Management and Operations, land use, and access management. Finally, the proposed solutions should align with current and likely future funding sources to ensure that they are feasible for implementation within the planning horizon.
