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 are considered heavy rail, using electric or diesel trains. Distance charges or zone pricing may be used.
A suburb is an area within a metropolitan area which often contains most of the area's economic activity, which may include commercial and mixed-use. A suburb can exist either as part of a larger city/urban area or as a separate political entity. The name describes an area that is either more or less densely populated than an inner city. In many metropolitan areas suburbs rise in population during the day and are where most jobs are located; being major commercial and job hubs, many suburbs also exist as separate residential communities within commuting distance of a larger city. Suburbs can have their own political or legal jurisdiction, 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., but it is used in contrast with inner city areas.
A metropolitan area or metro is a region consisting of a densely populated urban agglomeration and its surrounding territories sharing 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.
In the United States, a metropolitan statistical area (MSA) is a geographical region with a relatively high population density at its core and close economic ties throughout the region. Such regions are not legally incorporated as a city or town would be and are not legal administrative divisions like counties or separate entities such as states. As a result, sometimes the precise definition of a given metropolitan area will vary between sources. The statistical criteria for a standard metropolitan area were defined in 1949 and redefined as a metropolitan statistical area in 1983.
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 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.
Urban secession is a city's secession from its surrounding region to form a new political unit.
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. Regarding occupation, it is also colloquially called the journey to work. 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.
The Greater Tokyo Area is the most populous metropolitan area in the world, consisting of the Kantō region of Japan as well as the prefecture of Yamanashi of the neighboring Chūbu region. In Japanese, it is referred to by various terms, one of the most common being Capital Region.
Communauté urbaine is the second most integrated form of intercommunality in France, after the Metropolis. A communauté urbaine is composed of a city (commune) and its independent suburbs.
Edge city is a term that originated in the United States for 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.
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.
Suburbanization (AE), or suburbanisation (BE), is a population shift from historic core cities or rural areas into suburbs, resulting in the 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.
The transport network in Greater Tokyo includes public and private rail and highway networks; airports for international, domestic, and general aviation; buses; motorcycle delivery services, walking, bicycling, and commercial shipping. While the nexus is in the central part of Tokyo, every part of the Greater Tokyo Area has rail or road transport services. There are also a number of ports offering sea and air transport to the general public.
The Tulsa metropolitan area, officially defined as the Tulsa metropolitan statistical area is a metropolis in northeastern Oklahoma centered around the city of Tulsa and encompassing Tulsa, Rogers, Wagoner, Osage, Creek, Okmulgee and Pawnee counties. It had a population of 1,034,123 according to the 2022 U.S. census estimates.
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 Bilbao Metropolitan Area is the metropolitan area or continuous urban area based around the city of Bilbao, in the Basque Country, Spain. It comprises the city of Bilbao, the 25 municipalities that make the comarca of Greater Bilbao plus ten other surrounding municipalities, all of them in the province of Biscay.
A commuter town is a populated area that is primarily residential rather than commercial or industrial. Routine travel from home to work and back is called commuting, which is where the term comes from. A commuter town may be called by many other terms: "bedroom community", "bedroom town", "bedroom suburb" (US), "dormitory town", or "dormitory suburb" (Britain/Commonwealth/Ireland). In Japan, a commuter town may be referred to by the wasei-eigo coinage "bed town". The term "exurb" was used from the 1950s, but since 2006, is generally used for areas beyond suburbs and specifically less densely built than the suburbs to which the exurbs' residents commute.
The Western Suburbs is the western precinct of the city of Mumbai, India. The Western Suburbs consist of Andheri, Bandra, Bhayander, Borivali, Dahisar, Goregaon, Jogeshwari, Juhu, Kandivali, Khar, Malad, Mira Road, Santacruz and Vile Parle. Geographically, the Western Suburbs lie at the western part of Salsette Island, is a continuous urban sprawl spanning the areas from Bandra to Bhayander, which is separated by the Vasai Creek from Vasai-Virar city and Mithi River from Mumbai city district.
In urban planning, a historic core city or central city is the municipality with the largest 1940 population in the present metropolitan area. This term was retired by the US census bureau and replaced by the term principal city, which can include historic core cities and post-WWII cities. Metropolitan areas were no longer considered monocentric, but polycentric due to suburbanization of employment. A historic core city is not to be confused with the core of a metropolitan area which is defined as an urban area with a population of over 50,000 by the US census bureau.
Complete communities is an urban and rural planning concept that aims to meet the basic needs of all residents in a community, regardless of income, culture, or political ideologies through integrated land use planning, transportation planning, and community design. While the concept is used by many communities as part of their community plan, each plan interprets what complete community means in their own way. The idea of the complete community has roots in early planning theory, beginning with The Garden City Movement, and is a component of contemporary planning methods including Smart Growth.
