The Transportation Planning Unit is responsible for statewide long range planning and policy development, including creation and maintenance of the Oregon Transportation Plan and other modal plans, such as the Oregon Highway Plan. In addition the Unit is responsible for implementation of plans and policies through the preparation and dissemination of multi-modal, modal, and topic plans, policies, guidelines and administrative rules. A primary role of the Unit is to provide assistance designed to help achieve statewide consistency for transportation planning products and activities. In the development of planning and implementation materials, the Unit actively works with stakeholder committees and works to balance needs. The Unit also responds to legislative requirements, including initiatives such as Least Cost Planning and greenhouse gas (GHG) reduction planning, known as the Oregon Sustainable Transportation Initiative.
