Performance indicators for the I-205 corridor in the Vancouver region
Indicators
This dashboard shows three multimodal performance indicators for Interstate 205 in the Vancouver region: annual general purpose lane (GP) person miles traveled, annual GP vehicle delay, percentage of park and ride spaces occupied.
For details on methodology to calculate person miles traveled and vehicle delay, refer to WSDOT's
Handbook for Corridor Capacity Evaluation (PDF 5.9MB).

Multi-year trends
In 2021, annual person miles traveled and vehicle delay increased compared to 2020, but remained below pre-pandemic levels. In 2020, the statewide response to the COVID-19 mitigation policy, such as an increase in telework and no large gatherings of events, resulted in reduced traffic. This significantly reduced the person miles traveled and vehicle delay compared to previous years. From 2017 to 2019, the I-205 corridor in the Vancouver region experienced only small changes in person miles traveled. Annual vehicle delay experienced a slight decrease from 2017 to 2019. Then in 2020, delay significantly decreased to 3,200 because fewer vehicles were on the road. Then in 2021 it increased to 33,200.
Annual highlights
In 2021, annual person miles traveled and vehicle delay increased compared to 2020, but remained below pre-pandemic levels. Nearly 278.7 million person miles were traveled on I-205 between the I-5/I-205 interchange and the I-205 Glenn Jackson Bridge, up 12% from 249.8 million in 2020. Travelers on this corridor experienced 33,200 hours of vehicle delay in 2021, up 938% from 3,200 in 2020. In 2021, park and ride lots average usage on this corridor's (Andersen and Evergreen Transit Center) were 21.5%. Evergreen Transit Center became tempoary closed for use as Safe Parking Zone, which provides a place for people sheltering in their vehicles.
In 2020, the statewide response to COVID-19 resulted in a significant reduction in person miles traveled and annual delay.
