Every four years, Metro is required to update the Regional Transportation Plan, a guide for future investments in the region's transportation system.
The plan establishes policies and priorities for:
- travel by motor vehicle, transit, foot and bicycle
- movement of goods and services
- street design and the efficient management of the overall system
Each update is shaped by growth forecasts in population, jobs and travel. The plan also evaluates federal, state and local funding for transportation improvements, estimates project costs and proposes funding strategies.
Transportation alternatives such as transit, walking and bicycling are included in the plan, as are commuter rail and vanpools, telecommuting, ridesharing and other programs to reduce demand on the transportation system.
From the Regional Transportation Plan come specific plans and projects and the funding to complete them:
Recent and future updates
In June 2010 the plan was given a major update, termed the 2035 Regional Transportation Plan. In July 2014, it was updated again. This limited update will serve as a springboard for more discussion and updates in 2018.
In between full updates the plan can be amended to respond to changing local conditions and newly adopted plans. To be eligible to build a project with federal funds, a project must first be amended into the RTP. In 2013, these proposed projects from local jurisdictions amended the RTP:
- City of Beaverton
- City of Hillsboro
- City of Portland
- East Metro Connections Plan
- Oregon Department of Transportation
- Washington County
