Performance indicators for the I-5 corridor in the Vancouver region

Indicators

This dashboard shows three multimodal performance indicators of highway performance for Interstate 5 in the Vancouver region: annual person miles traveled, annual 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 5.9 MB).

Multi-year trends

In 2021, due to higher traffic volumes, annual person miles traveled and vehicle delay increased compared to 2020 but were still below pre-pandemic levels. In 2020, due to the statewide response to COVID-19, there was a significant reduction in volumes and delay compared to previous years. Annual vehicle delay increased every year from 2017 through 2019. From 2017 to 2019, the I-5 corridor in the Vancouver region experienced a slight increase in person miles traveled. In 2020, there was a 16% decrease in person miles traveled as well as a 97% decrease in vehicle delay.
