ART and Metrobus ridership is measured annually in terms of the number of people boarding vehicles. This measure is of unlinked passenger trips. If a single individual boards an ART bus and then transfers to another ART or Metrobus route to reach their final destination, then that is counted as two distinct, unlinked passenger trips. Data for this measure is collected annually from ART and Metrobus operators and tracked by Arlington's Mobility Lab.
For context, ART's annual revenue hours and miles are also collected. Revenue hours and miles are defined as the amount of time (hours) or distance (miles) Arlington's fixed routed bus system operates in revenue service (i.e. picking up or dropping off passengers).
Measuring the ridership of bus transit services provided in Arlington County can show the growth in usage—or decline—of the transit system. Tracking ridership conveys whether Arlington is successfully maximizing the use of its transit system. Increasing ridership overall would meet the Master Transportation Plan's goal of encouraging a low‐auto‐usage lifestyle. This measure relates to the MTP Goal 1: Provide High‐Quality Transportation Services.
However, increasing ridership must be taken in context with the increase in the level of service (number of revenue hours and miles operated annually). Increasing frequency of service can lead to increases in ridership.
Bus ridership has steadily increased every year, between 2010 and 2013. Annual unlinked passenger trips have increased by 6.9 percent, or approximately 1.3 million trips annually.
Within overall ridership, the share of transit riders using the ART system has also steadily risen. ART ridership made up 12.5 percent of all unlinked trips in 2013, compared to just 10.1 percent in 2010. Metrobus ridership has been stable between 2011- 2013.
While ART's ridership has risen between 2010 and 2013, so has the number of annual revenue hours and miles. During this period, revenue hours and miles increased by 43.2 percent and 48.1percent, respectively, while ART ridership increased by 32.8 percent.
Although the increase in service does not equate to a one-for-one percentage point increase in ridership, the increase in revenue hours and miles helped to expand accessibility of residents and workers to ART bus stops.
