Seattle's 2025 - 2029 CTR Strategic Plan

Strategic Plan Overview

Seattle's Commute Trip Reduction (CTR) program plays a crucial role in the city's effort to reduce congestion and provide mobility choices. The CTR program is a key transportation demand management effort toward mitigating the impacts of population and employment growth while facilitating a thriving business environment, diverse travel choices, and a reduction in transportation emissions. 

The 2025-2029 CTR Four-Year Plan was adopted by City Council on June 10th, 2025. This document establishes the vision for Seattle's program. The plan sets program performance targets and identifies program priorities and strategies for five years. It also includes a full analysis of the progress we made over the last few years, including both performance and program improvements. It outlines metrics and means for strengthening the program and measuring our progress.

The planning team's analysis indicated how the program should evolve by adapting to the changing city and its commuting patterns. This Plan includes both retained network geographies and updated Drive Alone Rate (DAR) targets from the previous, 2019-2023 CTR Strategic Plan.

CTR Networks

As in previous plans, the city is divided into geographic areas, called networks, for the purposes of target setting. Each network is assigned a target Drive Alone Rate (DAR) that CTR-affected employers located within that network will work to achieve. You can also refer to the 2013-2018 Networks and Targets to view information about the first program period when these networks were introduced into Seattle's program.
