The Massachusetts Bay Transportation Authority operates a large number of bus lines in the greater Boston area. Some routes are for transport within the city; others bring passengers from surrounding areas to stops on the rail lines (commuter or subway) of the MBTA.
The MBTA also operates bus rapid transit service; see the Silver Line article for more information.
The MBTA has a policy objective to provide transit
service within walking distance, defined as 1/4 mile, for all
residents living in areas with population densities greater than
5,000 people per square mile. Much of this service is provided by bus.
Vehicles
The MBTA uses trackless trolleys, dual mode buses, compressed-natural gas-powered buses, and conventional diesel buses. The MBTA is replacing replacement of two-thirds of its bus fleet with low-floor buses that have wheelchair ramps and audio/visual announcement technology. See MBTA accessibility.
