Commuter rail or suburban rail is a passenger rail transport service that primarily operates within a metropolitan area, connecting commuters to a central city from adjacent suburbs or commuter towns. Commuter rail systems can use locomotive-hauled trains or multiple units, using electric or diesel propulsion. Distance charges or zone pricing may be used.
A suburb is an area within a metropolitan area which is predominantly residential and within commuting distance of a large city. Suburbs can have their own political or legal jurisdictions, especially in the United States, but this is not always the case, especially in the United Kingdom, where most suburbs are located within the administrative boundaries of cities. In most English-speaking countries, suburban areas are defined in contrast to central city or inner city areas, but in Australian English and South African English, suburb has become largely synonymous with what is called a "neighborhood" in the U.S. Due in part to historical trends such as white flight, some suburbs in the United States have a higher population and higher incomes than their nearby inner cities.
Transportation in Boston includes roadway, subway, regional rail, air, and sea options for passenger and freight transit in Boston, Massachusetts. The Massachusetts Port Authority (Massport) operates the Port of Boston, which includes a container shipping facility in South Boston, and Logan International Airport, in East Boston. The Massachusetts Bay Transportation Authority (MBTA) operates bus, subway, short-distance rail, and water ferry passenger services throughout the city and region. Amtrak operates passenger rail service to and from major Northeastern cities, and a major bus terminal at South Station is served by varied intercity bus companies. The city is bisected by major highways I-90 and I-93, the intersection of which has undergone a major renovation, nicknamed the Big Dig.
A metropolitan area or metro is a region consisting of a densely populated urban agglomeration and its surrounding territories which share industries, commercial areas, transport network, infrastructures and housing. A metropolitan area usually comprises multiple principal cities, jurisdictions and municipalities: neighborhoods, townships, boroughs, cities, towns, exurbs, suburbs, counties, districts and even states and nations in areas like the eurodistricts. As social, economic and political institutions have changed, metropolitan areas have become key economic and political regions.
An exurb is an area outside the typically denser inner suburban area, at the edge of a metropolitan area, which has some economic and commuting connection to the metro area, low housing-density, and relatively high population-growth. It shapes an interface between urban and rural landscapes, holding a limited urban nature for its functional, economic, and social interaction with the urban center, due to its dominant residential character. Exurbs consist of "agglomerations of housing and jobs outside the municipal boundaries of a primary city" and beyond the surrounding suburbs.
Commuting is periodically recurring travel between a place of residence and place of work or study, where the traveler, referred to as a commuter, leaves the boundary of their home community. By extension, it can sometimes be any regular or often repeated travel between locations, even when not work-related. The modes of travel, time taken and distance traveled in commuting varies widely across the globe. Most people in least-developed countries continue to walk to work. The cheapest method of commuting after walking is usually by bicycle, so this is common in low-income countries but is also increasingly practised by people in wealthier countries for environmental and health reasons. In middle-income countries, motorcycle commuting is very common.
An edge city is a concentration of business, shopping, and entertainment outside a traditional downtown or central business district, in what had previously been a suburban, residential or rural area. The term was popularized by the 1991 book Edge City: Life on the New Frontier by Joel Garreau, who established its current meaning while working as a reporter for The Washington Post. Garreau argues that the edge city has become the standard form of urban growth worldwide, representing a 20th-century urban form unlike that of the 19th-century central downtown. Other terms for these areas include suburban activity centers, megacenters, and suburban business districts. These districts have now developed in many countries.
A satellite city or satellite town is a smaller municipality or settlement that is part of a larger metropolitan area and serves as a regional population and employment center. It differs from mere suburbs, subdivisions and especially bedroom communities in that it has employment bases sufficient to support its residential population, and conceptually, could be a self-sufficient community outside of its larger metropolitan area. However, it functions as part of a metropolis and experiences high levels of cross-commuting.
Urban sprawl is defined as "the spreading of urban developments on undeveloped land near a more or less densely populated city". Urban sprawl has been described as the unrestricted growth in many urban areas of housing, commercial development, and roads over large expanses of land, with little concern for very dense urban planning. Sometimes the urban areas described as the most "sprawling" are the most densely populated. In addition to describing a special form of urbanization, the term also relates to the social and environmental consequences associated with this development. In modern times some suburban areas described as "sprawl" have less detached housing and higher density than the nearby core city. Medieval suburbs suffered from the loss of protection of city walls, before the advent of industrial warfare. Modern disadvantages and costs include increased travel time, transport costs, pollution, and destruction of the countryside. The revenue for building and maintaining urban infrastructure in these areas are gained mostly through property and sales taxes. Most jobs in the US are now located in suburbs generating much of the revenue, although a lack of growth will require higher tax rates.
A streetcar suburb is a residential community whose growth and development was strongly shaped by the use of streetcar lines as a primary means of transportation. Such suburbs developed in the United States in the years before the automobile, when the introduction of the electric trolley or streetcar allowed the nation’s burgeoning middle class to move beyond the central city’s borders. Early suburbs were served by horsecars, but by the late 19th century cable cars and electric streetcars, or trams, were used, allowing residences to be built farther away from the urban core of a city. Streetcar suburbs, usually called additions or extensions at the time, were the forerunner of today's suburbs in the United States and Canada. San Francisco's Western Addition is one of the best examples of streetcar suburbs before westward and southward expansion occurred.
In urban planning, transit-oriented development (TOD) is a type of urban development that maximizes the amount of residential, business and leisure space within walking distance of public transport. It promotes a symbiotic relationship between dense, compact urban form and public transport use. In doing so, TOD aims to increase public transport ridership by reducing the use of private cars and by promoting sustainable urban growth.
Suburbanization, also spelled suburbanisation, is a population shift from historic core cities or rural areas into suburbs. Most suburbs are built in a formation of (sub)urban sprawl. As a consequence of the movement of households and businesses away from city centers, low-density, peripheral urban areas grow. Proponents of curbing suburbanization argue that sprawl leads to urban decay and a concentration of lower-income residents in the inner city, in addition to environmental harm.
Rockingham is a community located within the urban area of the Halifax Regional Municipality, in Nova Scotia, Canada.
The Greater London Built-up Area, or Greater London Urban Area, is a conurbation in south-east England that constitutes the continuous urban sprawl of London, and includes surrounding adjacent urban towns as defined by the Office for National Statistics. It is the largest urban area in the United Kingdom with a population of 9,787,426 in 2011.
The Thessaloniki metropolitan area or larger urban zone (LUZ) is the complete area covered and directly influenced by Thessaloniki. The metropolitan area traditionally consisted of the municipality of Thessaloniki and its immediate surroundings, which is today referred to as the Thessaloniki urban area. However, since the mid to late 1990s, the areas surrounding the urban area have succumbed to urban sprawl and what used to be agrarian communities are rapidly urbanizing and being developed into suburbs or exurbs. This is creating new problems for a region already facing issues such as pollution, traffic congestion and social ills.
California's transportation system is complex and dynamic. Although known for its car culture and extensive network of freeways and roads, the state also has a vast array of rail, sea, and air transport. Several subway, light rail, and commuter rail networks are found in many of the state's largest population centers. In addition, with the state's location on the West Coast of the United States, several important ports in California handle freight shipments from the Pacific Rim and beyond. A number of airports are also spread out across the state, ranging from small general aviation airports to large international hubs like Los Angeles International Airport and San Francisco International Airport.
An inner suburb is a suburban community central to a large city, or at the inner city and central business district. The urban density is usually lower than the inner city or central business district, but higher than that of the city's rural–urban fringe, or exurbs.
A reverse commute is a round trip, regularly taken, from an urban area to a suburban one in the morning, and returning in the evening. It is almost universally applied to trips to work in the suburbs from homes in the city. This is in opposition to the regular commute, where a person lives in the suburbs and travels to work in the city.
The Metropolitan Green Belt is a statutory green belt around London, England.
