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:

  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 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 2022, annual person miles traveled and vehicle delay increased compared to 2021, due to the ongoing recovery of traffic volume in the wake of COVID-19. Annual person miles traveled in 2022 was close to the pre-pandemic level, while vehicle delay was still much lower than the pre-pandemic level.

In 2020, due to the statewide response to COVID-19, there was a significant reduction in volumes and delay compared to previous years.

From 2018 to 2019, annual person miles decreased slightly, but vehicle delay increased significantly.
