Given the question: Information: - The Massachusetts Bay Transportation Authority (abbreviated the MBTA and The T) is the public agency responsible for operating most public transportation services in the Greater Boston, Massachusetts region. Earlier modes of public transportation in Boston were independently owned and operated; they were first folded into a single agency with the formation of the Metropolitan Transit Authority (MTA) in 1947. The original MTA was replaced with the present-day MBTA in 1964, which was established as an individual department within the Commonwealth of Massachusetts before becoming a division of the Massachusetts Department of Transportation (MassDOT) in 2009. - Rapid transit, also known as heavy rail, metro, subway, tube, or underground, is a type of high-capacity public transport generally found in urban areas. Unlike buses or trams, rapid transit systems are electric railways that operate on an exclusive right-of-way, which cannot be accessed by pedestrians or other vehicles of any sort, and which is often grade separated in tunnels or on elevated railways. - Physical accessibility on the Massachusetts Bay Transportation Authority (MBTA or "the T") system is incomplete but improving, with accessibility on all buses (including the Silver Line), all Orange Line stations, all but 2 Red Line stations, and all but 1 Blue Line station. As is true for most mass transit systems, much of the Boston subway and commuter rail lines were built before wheelchair access was a requirement. The Boston system underwent significant expansion in the 1980s and 1990s, and all the new facilities are ADA compliant. The MBTA has also refurbished many stations, and these too are accessible. More improvements are in progress or expected as part of planned construction. - Bus rapid transit (BRT, BRTS, busway, transitway) is a bus-based public transport system designed to improve capacity and reliability relative to a conventional bus system. Typically, a BRT system includes roadway that is dedicated to buses, and gives priority to buses at intersections where buses may interact with other traffic; alongside design features to reduce delays caused by passengers boarding or leaving buses, or purchasing fares. - Union Park Street is a street level Bus Rapid Transit ( BRT ) stop on the MBTA Silver Line Washington Street line , located on Washington St at Union Park St. The bus stops are staggered , with the inbound stop in front of Cathedral High School , and the outbound stop near Union Park . Union Park Street is fully accessible ( see MBTA accessibility ) . - Accessibility refers to the design of products, devices, services, or environments for people who experience disabilities. The concept of accessible design and practice of accessible development ensures both "direct access" (i.e. unassisted) and "indirect access" meaning compatibility with a person's assistive technology (for example, computer screen readers). - A wheelchair, often abbreviated to just "chair", is a chair with wheels, used by people for whom walking is difficult or impossible due to illness, injury, or disability. Wheelchairs come in a wide variety of formats to meet the specific needs of their users. They may include specialized seating adaptions, individualized controls, and may be specific to particular activities, as seen with sports wheelchairs and beach wheelchairs. The most widely recognised distinction is between powered wheelchairs ("powerchairs"), where propulsion is provided by batteries and electric motors, and manually propelled wheelchairs, where the propulsive force is provided either by the wheelchair user/occupant pushing the wheelchair by hand ("self-propelled"), or by an attendant pushing from the rear ("attendant propelled"). - Traffic on roads may consist of pedestrians, ridden or herded animals, vehicles, streetcars, buses and other conveyances, either singly or together, while using the public way for purposes of travel. Traffic laws are the laws which govern traffic and regulate vehicles, while rules of the road are both the laws and the informal rules that may have developed over time to facilitate the orderly and timely flow of traffic.
