COVID-19 Multimodal Transportation System Performance Dashboard

Washington state has seen a significant decline in travel across all modes of transportation since mid-March. Washingtonians have responded positively to Gov. Inslee’s various COVID-19 related initiatives such as closing schools (March 12), restricting gatherings to fewer than 50 people (March 16), and the Stay Home – Stay Healthy Executive Order (March 25).

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 year 2019. For example, Wednesday, April 3, 2019 would serve as the baseline for comparing the volume data from Wednesday, April, 1, 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.
