COVID-19 Multimodal Transportation System Performance Dashboard

Washington state has seen a significant decline in travel across all modes of transportation since mid-March 2020. Washingtonians have responded positively to Gov. Inslee’s various COVID-19 related initiatives over the past year to curb the spread of the virus, which has resulted in positive outcomes for the state residents.

Multimodal travel changes in Highway Traffic, Toll Systems, and Ferries, Transit and Passenger Rail ridership are reflected in the executive summary below. For deeper dives into the data and daily updates on COVID-19’s effects on items ranging from Freight and Safety to Aviation, see buttons below.

This dashboard is updated by 10:30 a.m. on weekdays (Monday through Friday). The latest data displayed on Fridays, Saturdays and Sundays is for the previous Thursday. Data for Fridays, Saturdays and Sundays is added to the dashboard the following Monday.

WSDOT is monitoring these system-wide transportation changes based on data from WSDOT Traffic Information, the Washington State Transit Association and the Port of Seattle (Seattle-Tacoma International Airport).

Note: Baseline is defined as volume number from the same weekday of the same month from the baseline year*. For example, Wednesday, April 3, 2019 would serve as the baseline for comparing the volume data from Wednesday, April, 1, 2020. *Baseline year is defined as March 2019 to Feb 2020. The dramatic increase shown for Thursday, July 2, 2020 is because the comparison day aligns with Thursday, July 4, 2019 and the holiday travel associated with that date. The increase shown for Wednesday, December 22, 2020 is because the comparison day aligns with Wednesday, December 24, 2019 and the holiday travel pattern associated with that date.
