Public transportation in the United States

In the mid-1950s more than 2,000 buses operated by Greyhound Lines, Trailways, and other companies connected 15,000 cities and towns. Passenger volume decreased as a result of expanding road and air travel, and urban decay that caused many neighborhoods with bus depots to become more dangerous. In 1960, American intercity buses carried 140 million riders; the rate decreased to 40 million by 1990, and continued to decrease until 2006.[15]

By 1997, intercity bus transportation accounted for only 3.6% of travel in the United States.[16] In the late 1990s, however, Chinatown bus lines that connected New York with Boston and Philadelphia's Chinatowns began operating. They became popular with non-Chinese college students and others who wanted inexpensive transportation, and between 1997 and 2007 Greyhound lost 60% of its market share in the northeast United States to the Chinatown buses. During the following decade, new bus lines such as Megabus and BoltBus emulated the Chinatown buses' practices of low prices and curbside stops on a much larger scale, both in the original Northeast Corridor and elsewhere, while introducing yield management techniques to the industry.[15][17][18]

By 2010 curbside buses' annual passenger volume had risen by 33% and they accounted for more than 20% of all bus trips.[15] One analyst estimated that curbside buses that year carried at least 2.4 billion passenger miles in the Northeast Corridor, compared to 1.7 billion passenger miles for Amtrak trains.[17] Traditional depot-based bus lines also grew, benefiting from what the American Bus Association called "the Megabus effect",[15] and both Greyhound and its subsidiary Yo! Bus, which competed directly with the Chinatown buses, benefited after the federal government shut several Chinatown lines down in June 2012.[18]

Between 2006 and 2014, American intercity buses focused on medium-haul trips between 200 and 300 miles; airplanes performed the bulk of longer trips and automobiles shorter ones. For most medium-haul trips curbside bus fares were less than the cost of automobile gasoline, and one tenth that of Amtrak. Buses are also four times more fuel-efficient than automobiles. Their Wi-Fi service is also popular; one study estimated that 92% of Megabus and BoltBus passengers planned to use an electronic device.[15] New lower fares introduced by Greyhound on traditional medium-distance routes and rising gasoline prices have increased ridership across the network and made bus travel cheaper than all alternatives.

Effective June 25, 2014, Greyhound reintroduced many much longer bus routes, including New York-Los Angeles, Los Angeles-Vancouver, and others, while increasing frequencies on existing long-distance and ultra-long-distance buses routes. This turned back the tide of shortening bus routes and puts Greyhound back in the position of competing with long-distance road trips, airlines, and trains. Long distance buses were to have Wi-Fi, power outlets, and extra legroom, sometimes extra recline, and were to be cleaned, refueled, and driver-changed at major stations along the way, coinciding with Greyhound's eradication of overbooking. It also represented Greyhound's traditional bus expansion over the expansion of curbside bus lines.[19]

The GRTC Pulse bus rapid transit has serviced Richmond, Virginia since June 2018.

Bus rapid transit (BRT), also called a busway, is a bus-based public transport system designed to improve capacity and reliability relative to a conventional bus system.[20] Typically, a BRT system includes roadways that are 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. BRT aims to combine the capacity and speed of a metro with the flexibility, lower cost and simplicity of a bus system.

In the United States several moderately sized cities have BRT as an alternative to light rail due to perceived costs and political will. Notable examples of moderately sized cities with BRT as their fulcrum of public transportation include the Silver Line in Grand Rapids, Michigan, the GRTC Pulse in Richmond, Virginia, and the BusPlus in Albany, New York. Several satellite and suburban cities to larger cities also have bus rapid transit systems as secondary public transit services to light rail and commuter rail. For example, the Salt Lake City suburb of Murray has the planned Murray Taylorsville MAX BRT route. The Denver suburb of Fort Collins, and the Washington, D.C. suburbs of Arlington and Alexandria, Virginia contain the Metroway system.

Some major cities have their own BRT routes within city limits that function as their own rapid transit line, or as auxiliary routes to the rail lines in their respective city. In Cleveland, the HealthLine, which is considered a standard for BRT in the United States, serves most of the city. Minneapolis has the Red Line, and Los Angeles has the F Line, which does have plans to upgrade to light rail.

Commuter bus systems are generally categorized as public transit, especially for large metropolitan transit networks. Usually these routes cover a long distance compared to most transit bus routes, but still short—usually 40 miles in one direction. An urban-suburban bus line generally connects a suburban area to the downtown core.

The vehicle can be something as simple as a merely refitted school bus (which sometimes already contains overhead storage racks) or a minibus. Often a suburban coach may be used, which is a standard transit bus modified to have some of the functionality of an interstate coach. The vehicles provide accommodation for the disabled (through a lift or ramp at the front), and thus has a few high-back seats, usually in the front, that can be folded up for wheelchairs. The rest of the seats are reclining upholstered seats and have individual lights and overhead storage bins. Because it is a commuter bus, it has some (but not much) standing room, stop-request devices, and a farebox. This model also has a bike rack at the front to accommodate two bicycles.

Suburban models in the United States are often used in Park-and-Ride services, and are very common in the New York City area, where New Jersey Transit Bus Operations is a major operator serving widespread bedroom communities.
