Measures of public transit ridership on I-5 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 I-5 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, refer to 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 I-5 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 reveal how these percentages vary by location, time of day, direction of travel and year.
