Central Puget Sound State Route 167 - Dashboard


On this page:

Performance indicators for the SR 167 corridor in the central Puget Sound region.

Indicators

This dashboard shows three multimodal performance indicators for State Route 167 in the central Puget Sound region:

  1. Annual general purpose (GP) lane person miles traveled
  2. Annual GP vehicle delay
  3. Percentage of park and ride spaces occupied.



For details on the methodology used to calculate person miles traveled and vehicle delay, refer to WSDOT's Handbook for Corridor Capacity Evaluation (PDF 5.9MB).

Note: Park & Rides utilization rates data will no longer available from 2020.

Multi-year trends

In 2022, annual GP person miles traveled did not change significantly compared t0 2021. Delay continued to increase compared to 2021, due to the ongoing recovery of traffic volume in the wake of COVID-19. However, person miles traveled and delay were still lower than the pre-pandemic levels.

In 2020, the statewide response to the COVID-19 mitigation policy, such as increased telework and no large gatherings of events, resulted in reduced traffic. This significantly reduced the GP person miles traveled and vehicle delay compared to previous years.

From 2018 through 2019, the central Puget Sound region experienced substantial economic growth and increases in employment, which resulted in more commuters on SR 167. Annual GP person miles traveled on SR 167 were very high between 2018 and 2019, as was annual GP vehicle delay.

Highway capacity constraints vary based on the presence of managed lanes and multimodal travel options; the SR 167 corridor is served by the Sounder commuter rail, transit buses, and high occupancy toll lanes.

However, the vehicle delay increased significantly from 2021: Travelers on this corridor experienced 328,000 hours of vehicle delay in 2022, up 74% from 189,000 hours in 2021.

In 2021, annual GP person miles traveled and vehicle delay increased from 2020, due to the recovery of traffic volume in the wake of COVID-19.
