Total Bus Boardings in Arizona Cities
Public transit in the Phoenix and Tucson metro areas is composed primarily of bus service, with neighborhood shuttles and circulators and regional shuttles helping to extend service. Historically, Maricopa County has had low levels of bus ridership per capita. Ridership has increased primarily as a result of population growth. As people become more aware of the benefits of public transportation, both to themselves and to the environment, ridership will continue to grow.
