Vancouver region Interstate 5 - Transit ridership

Measures of public transit ridership on the I-5 corridor in the Vancouver area
Transit ridership
WSDOT works with transit agencies in major urban areas throughout the state to collect data on the number of transit vehicles and passengers that pass specific points on select urban highway corridors, including the I-5 corridor in the Vancouver region between the I-205 interchange and the Columbia River. WSDOT combines this data with its highway vehicle and person throughput data to produce the measures below. For more information on how WSDOT calculates vehicle and person throughput, see WSDOT's Handbook for Corridor Capacity Evaluation (PDF 5.9MB).
The chart below shows the average percentage of buses compared to all vehicles passing select points on the I-5 corridor in the Vancouver region, and the average percentage of bus riders compared to all highway users passing those points. Use the drop-down menus in the chart to see how these percentages vary by location, time of day, direction of travel and year.

Note: Charts showing 0.0% may indicate smaller values (for example, 0.04%).
Multi-year trends
In 2022, transit ridership did not change compared to 2021. Transit ridership in 2022 was still lower than the pre-pandemic level.
In 2020, due to the statewide response to COVID-19, there was a significant decrease in transit ridership compared to previous years.
Annual highlights
In 2022, transit ridership experienced almost no changes compared to 2021. Southbound I-5 at the Interstate Bridge during morning commute experienced a slight decrease in transit vehicles which were 0.7% of all vehicles moved 0.6% of all travelers.
In 2021, transit ridership rebounded slightly compared to 2020 but was still lower than the pre-pandemic level. Transit vehicles which were 0.8% of all vehicles moved 0.8% of all travelers on southbound I-5 at the Interstate Bridge during morning commute.
In 2020, due to the statewide response to COVID-19 there was a significant decrease in transit ridership compared to previous years. Buses (0.4% of all vehicles) moved 0.4% of travelers during the southbound morning commute on I-5 at the Interstate Bridge, and some transit routes were temporarily suspended.
In 2019, buses (0.5% of all vehicles) moved 7.7% of travelers during the southbound morning commute on I-5 at the Interstate Bridge. During the northbound evening commute at the same location, buses (0.4% of all vehicles) moved 6.8% of travelers.
Transit ridership data was not collected for 2018 due to a pause in publication while WSDOT conducted an engagement process to inform the redesign of this dashboard. Following input from its transit agency partners, WSDOT switched from commute-level transit ridership measures to analyzing transit ridership at select locations along urban highway corridors. This change helped to streamline the collaboration process.
