- People who were provided fully subsidized fares used the King County Metro transit system at double the rate than those who received only a partially subsidized fare.
- Riders leveraging fully subsidized fares did not overwhelm the transit system at peak travel times.
- Everyone who received fully subsidized fares, whether they had frequently or infrequently used the transit system prior to the study, used the transit system more often.
King County Metro Transit (Metro) is part of a large integrated regional transit system that offers a range of transportation options to a bustling county with a unique geography. Riders pay a flat fare of $2.75 on Metro buses, regardless of day or time, distance traveled, or time spent aboard. To make transit services more affordable and accessible for all King County residents, Metro launched the ORCA LIFT program, which reduced fares to a flat rate of $1.50 per ride on buses and light rail for people with incomes at or below 200% of the federal poverty level.
However, Metro’s work with community stakeholders revealed a need for additional support for residents with the lowest incomes. So, Metro partnered with LEO to understand the effect that a fully subsidized fare program would have on low-income riders.
LEO’s randomized controlled trial with King County Metro began in March 2019 and included 1,797 low-income Metro riders divided into two cohorts. The first cohort included enrollees from March to July 2019. Enrollment for the second cohort began in December 2019 and was intended to go through April 2020 but was interrupted by the beginning of the Covid-19 pandemic in March 2020.
Within each cohort, riders were randomly assigned to either the treatment or the control group. The treatment group received an ORCA LIFT card pre-loaded with up to 24 weeks of fully subsidized transit. The control group received an ORCA LIFT card pre-loaded with $10 worth of free transit, which is the standard card given to riders seeking public assistance. Participants completed a short intake questionnaire to determine their baseline transit habits. LEO researchers used the ORCA LIFT registry to connect administrative data with ORCA LIFT card boarding data and conducted follow-up surveys to determine how the fully subsidized fares impacted ridership outcomes.
What We Learned
Results of the ORCA LIFT study indicate that access to free transportation significantly increases ridership. People who received the fully subsidized fares used the bus system twice as often as those who received only the partially subsidized fare. This indicates that cost may be a critical barrier keeping low-income King County residents from using the Metro system, irrespective of age or race.
Importantly, researchers learned that access to fully subsidized fares cannot make up for the lack of physical public transportation stops in some neighborhoods. The positive effect of fully subsidized fares disappeared in neighborhoods that had no bus stops.
The study also shows that increased access to fully subsidized fares does not seem to place any additional burden on the transit system. Even though ridership increased for the most frequent riders, as well as those who had little-to-no transit experience prior to enrolling in the study, results show that access to these fares increased ridership the most during off-peak hours and on routes that were not overly crowded to begin with.
Where We’re Going
The ORCA LIFT study presents clear evidence that fully subsidizing public transportation costs for low-income individuals increases their use of the transit system and access to locations throughout King County. Still, we need to know more about how increased access to and use of public transportation helps people live their best lives. LEO is now evaluating the impact of fully subsidized fares on outcomes such as financial stability, employment, and subjective well-being measures for those most in need. LEO is also conducting an evaluation of Metro’s fully subsidized fare program to determine the impact to those with very low incomes.
