Performance indicators for I-5 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).
