Daily Urban System
The daily urban system (DUS) refers to the area around a city, in which daily commuting occurs. It is a means for defining an urban area, urban region by including the areas from which individuals commute. Daily Urban System is a concept first introduced by the American geographer Berry, and then introduced into Europe by the British geographer Hall. Definition Daily urban system (DUS) mainly focuses on urban cities, where majority of the commuting flow take place. However, some case studies do look at the outskirts and suburban areas around specific urban cities that are being studied. The daily commuting includes both work and leisure, contributing to high density in the daily urban system. That results in slowering the speed of transportation. The speed of transportation is about 16 km/h at the central parts of urban cities, but speed may vary from place to place. Urban sprawl is the possible outcome of an expansion of the daily urban system. Therefore, it includes multiple ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Urban Area
An urban area, built-up area or urban agglomeration is a human settlement with a high population density and infrastructure of built environment. Urban areas are created through urbanization and are categorized by urban morphology as cities, towns, conurbations or suburbs. In urbanism, the term contrasts to rural areas such as villages and hamlets; in urban sociology or urban anthropology it contrasts with natural environment. The creation of earlier predecessors of urban areas during the urban revolution led to the creation of human civilization with modern urban planning, which along with other human activities such as exploitation of natural resources led to a human impact on the environment. "Agglomeration effects" are in the list of the main consequences of increased rates of firm creation since. This is due to conditions created by a greater level of industrial activity in a given region. However, a favorable environment for human capital development would also be genera ...

Exurb
An exurb (or alternately: exurban area) 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. They consist of "agglomerations of housing and jobs outside the municipal boundaries of a primary city" and beyond the surrounding suburbs. Definitions The word ''exurb'' (a portmanteau of ''extra (outside)'' and ''urban'') was coined by Auguste Comte Spectorsky, in his 1955 book ''The Exurbanites'', to describe the ring of prosperous communities beyond the suburbs, that are commuter towns for an urban area. In other uses the term has expanded to include popular extraurban districts which nonetheless may have poor transportation and under ...

Urbanization
Urbanization (or urbanisation) refers to the population shift from rural to urban areas, the corresponding decrease in the proportion of people living in rural areas, and the ways in which societies adapt to this change. It is predominantly the process by which towns and cities are formed and become larger as more people begin living and working in central areas. Although the two concepts are sometimes used interchangeably, urbanization should be distinguished from urban growth. Urbanization refers to the ''proportion'' of the total national population living in areas classified as urban, whereas urban growth strictly refers to the ''absolute'' number of people living in those areas. It is predicted that by 2050 about 64% of the developing world and 86% of the developed world will be urbanized. That is equivalent to approximately 3 billion urbanites by 2050, much of which will occur in Africa and Asia. Notably, the United Nations has also recently projected that nearly all gl ...

Urban Planning
Urban planning, also known as town planning, city planning, regional planning, or rural planning, is a technical and political process that is focused on the development and design of land use and the built environment, including air, water, and the infrastructure passing into and out of urban areas, such as transportation, communications, and distribution networks and their accessibility. Traditionally, urban planning followed a top-down approach in master planning the physical layout of human settlements. The primary concern was the public welfare, which included considerations of efficiency, sanitation, protection and use of the environment, as well as effects of the master plans on the social and economic activities. Over time, urban planning has adopted a focus on the social and environmental bottom-lines that focus on planning as a tool to improve the health and well-being of people while maintaining sustainability standards. Sustainable development was added as one of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Human Geography
Human geography or anthropogeography is the branch of geography that studies spatial relationships between human communities, cultures, economies, and their interactions with the environment. It analyzes spatial interdependencies between social interactions and the environment through qualitative and quantitative research methods. History Geography was not recognized as a formal academic discipline until the 18th century, although many scholars had undertaken geographical scholarship for much longer, particularly through cartography. The Royal Geographical Society was founded in England in 1830, although the United Kingdom did not get its first full Chair of geography until 1917. The first real geographical intellect to emerge in the United Kingdom was Halford John Mackinder, appointed reader at Oxford University in 1887. The National Geographic Society was founded in the United States in 1888 and began publication of the ''National Geographic'' magazine which became, and con ...

Urban Employment Area
is a definition of metropolitan areas used in Japan, defined by the Center for Spatial Information Service of the University of Tokyo. Japan's Ministry of Economy, Trade and Industry defined 233 areas for the UEAs of Japan. It is different from the definition of metropolitan areas defined in census by the Ministry of Internal Affairs and Communications. For the latter scheme, see the List of metropolitan areas in Japan article. The basic principle of UEA is similar to that of the Statistics Bureau definition; a central city and its associated outlying municipalities with certain numbers of commuters. A UEA with at least 50,000 DID (Densely Inhabited District) population is called or MEA for short in English. A UEA with at least 10,000 and less than 50,000 DID population is called or McEA for short in English. Definition ;Central city: *If a municipality has at least 10,000 DID population, and is not a suburb of any other municipalities, it is defined as a central city. *Even i ...

Travel To Work Area
A travel to work area or TTWA is a statistical tool used by UK Government agencies and local authorities, especially by the Department for Work and Pensions and Jobcentres, to indicate an area where the population would generally commute to a larger town, city or conurbation for the purposes of employment. Significance As a measure based on urban areas and their commuter hinterland they are a form of metropolitan area, though as methods of calculation differ they cannot directly be compared with other specific measurements such as metropolitan statistical areas in the United States. TTWAs have no legal status. However, they give planners and geographers an alternate view of urban life as their boundaries are tied not to arbitrary administrative limits but socio-economic ties. Having an idea of where people commute from for work is particularly useful for public transport planning.

Transit Desert
A transit desert is an area with limited transportation supply. Developed from the concept of food deserts, various methods have been proposed to measure transit deserts. Transit deserts are generally characterized by poor public transportation options and possibly poor bike, sidewalk, or road infrastructure. The lack of transportation options present in transit deserts may have negative effects of people’s health, job prospects, and economic mobility. History The term ‘desert’ has been variously applied to areas that lack key services like banks, food access, or even books. The idea of transit deserts was coined by Dr. Junfeng Jiao and Maxwell Dillivan, first appearing in print in 2013. Since that time the concept of transit deserts has been expanded upon and competing definitions and measurement techniques have emerged. Definitions Gap-based measurements Gap-based measurement techniques are the most prominent and well-defined definition of transit deserts. Such metho ...

Isochrone Map
An isochrone map in geography and urban planning is a map that depicts the area accessible from a point within a certain time threshold. An isochrone (iso = equal, chrone = time) is defined as "a line drawn on a map connecting points at which something occurs or arrives at the same time". In hydrology and transportation planning isochrone maps are commonly used to depict areas of equal travel time. The term is also used in cardiology as a tool to visually detect abnormalities using body surface distribution. History Early examples of Isochrone maps include the Galton's ''Isochronic Postal Charts'' and ''Isochronic Passage Charts'' of 1881 and 1882, Bartholomew's ''Isochronic Distance Map and Chart'' first published 1889 and Albrecht Penck's ''Isochronenkarte'' first published 1887. Where as Galton and the Bartholomews published maps depicting the days or weeks it took to travel long distances, Albrecht further developed the idea to not only depict long distances and world tra ...

Commuting Zone
A commuting zone is a geographic area used in population and economic analysis. In addition to the major use of urban areas, it may be used to define rural areas which share a common market.Tolbert, C. and M. Sizer. 1996.

Urban Sprawl
Urban sprawl (also known as suburban sprawl or urban encroachment) is defined as "the spreading of urban developments (such as houses and shopping centers) on undeveloped land near a 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 urban planning. In addition to describing a special form of urbanization, the term also relates to the social and environmental consequences associated with this development. Medieval suburbs suffered from 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 cost of building urban infrastructure for new developments is hardly ever recouped through property taxes, amounting to a subsidy for the developers and new residents at the expense of existing property taxpayers.

Commuter Town
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" (Canada and northeastern US), "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 . 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. Causes Often commuter towns form when workers in a region cannot afford to live where they work and must seek residency in another town with a lower cost of living. The late 20th century, the dot-com bubble and United States housing bubble drove housing costs in Californian metropolitan areas to hist ...
