Statewide Transportation Strategy

The Oregon Statewide Transportation Strategy, or STS, is a state-level scenario planning effort that examines all aspects of the transportation system, including the movement of people and goods, and identifies a combination of strategies to reduce greenhouse gas, or GHG, emissions. The STS identifies a variety of effective GHG emissions reduction strategies in transportation systems, vehicle and fuel technologies, and urban land use patterns.

The STS was developed as part of the Oregon Sustainable Transportation Initiative program and involved extensive research and technical analysis, as well as policy direction and technical input from local governments, industry representatives, metropolitan planning organizations, state agencies and others. In 2018, the Oregon Transportation Commission adopted an amendment to incorporate the STS as part of the Oregon Transportation Plan.

STS Short-Term Implementation Plan

The STS Short-Term Implementation Plan identifies action items for Oregon Department of Transportation to implement in 2-5 years to help move Oregon towards achieving the STS vision.

With a horizon year of 2050, implementing the STS will be an ongoing, long-term process that will likely include the development of mid-term and long-term implementation plans. As such, ODOT remains committed to ongoing stakeholder engagement throughout the implementation process.

STS Monitoring Report

The STS is monitored over time to track progress towards the state's GHG reduction goals. A 2018 Monitoring Report summarized ODOT-led actions in the first 5 years and overall progress towards achieving the STS vision. The report showed that ODOT was advancing the STS vision within the activities it has authority over.

In 2023 ODOT created the Oregon Transportation Emissions website, in cooperation with state agency partners.  The site has a more accessible summary of the actions included in the STS and transparency in multi-agency progress on those actions. 2022 updates showed significant progress in cleaning up each vehicle mile, while reducing the growth in vehicle miles travelled had the most opportunities for improvement. ODOT, as part of the multi-agency Every Mile Counts program, is focused on continued planning and implementation actions to reduce transportation sector emissions.
