Compact City
The compact city or city of short distances is an urban planning and urban design concept, which promotes relatively high residential density with mixed land uses. It is based on an efficient public transport system and has an urban layout which – according to its advocates – encourages walking and cycling, low energy consumption and reduced pollution. A large resident population provides opportunities for social interaction as well as a feeling of safety in numbers and "eyes on the street".'' The Death and Life of Great American Cities'' (1961) New York: Random House. It is also arguably a more sustainable urban settlement type than urban sprawl because it is less dependent on the car, requiring less (and cheaper per capita) infrastructure provision (Williams 2000, cited in Dempsey 2010). Achieving a compact city does not just mean increasing urban density ''per se'' or across all parts of the city. It means good planning to achieve an ''overall'' more compact urban form: ...

Road Space Requirements
A road is a thoroughfare used primarily for movement of traffic. Roads differ from streets, whose primary use is local access. They also differ from stroads, which combine the features of streets and roads. Most modern roads are Road surface, paved. The words "road" and "street" are commonly considered to be interchangeable, but the distinction is important in urban design. There are road hierarchy, many types of roads, including parkways, avenue (landscape), avenues, controlled-access highways (freeways, motorways, and expressways), tollways, interstates, highways, and local roads. The primary features of roads include lanes, sidewalks (pavement), roadways (carriageways), median strip, medians, shoulder (road), shoulders, road verge, verges, bike paths (cycle paths), and shared-use paths. Definitions Historically, many roads were simply recognizable routes without any formal construction or some maintenance. The Organisation for Economic Co-operation and Development, Organi ...

Smart Growth
Smart growth is an urban planning and transportation theory that concentrates growth in compact walkable urban centers to avoid sprawl. It also advocates compact, transit-oriented, walkable, bicycle-friendly land use, including neighborhood schools, complete streets, and mixed-use development with a range of housing choices. The term "smart growth" is particularly used in North America. In Europe and particularly the UK, the terms " compact city", " urban densification" or "urban intensification" have often been used to describe similar concepts, which have influenced government planning policies in the UK, the Netherlands and several other European countries. Smart growth values long-range, regional considerations of sustainability over a short-term focus. Its sustainable development goals are to achieve a unique sense of community and place; expand the range of transportation, employment, and housing choices; equitably distribute the costs and benefits of development; pre ...

European Commission
The European Commission (EC) is the primary Executive (government), executive arm of the European Union (EU). It operates as a cabinet government, with a number of European Commissioner, members of the Commission (directorial system, informally known as "commissioners") corresponding to two thirds of the number of Member state of the European Union, member states, unless the European Council, acting unanimously, decides to alter this number. The current number of commissioners is 27, including the president. It includes an administrative body of about 32,000 European civil servants. The commission is divided into departments known as Directorate-General, Directorates-General (DGs) that can be likened to departments or Ministry (government department), ministries each headed by a director-general who is responsible to a commissioner. Currently, there is one member per European Union member state, member state, but members are bound by their oath of office to represent the genera ...

Carfree Zone
Pedestrian zones (also known as auto-free zones and car-free zones, as pedestrian precincts in British English, and as pedestrian malls in the United States and Australia) are areas of a city or town restricted to use by people on foot or human-powered transport such as bicycles, with non-emergency motor traffic not allowed. Converting a street or an area to pedestrian-only use is called ''pedestrianisation''. Pedestrianisation usually aims to provide better accessibility and mobility for pedestrians, to enhance the amount of shopping and other business activities in the area or to improve the attractiveness of the local environment in terms of aesthetics, air pollution, noise and crashes involving motor vehicle with pedestrians. In some cases, motor traffic in surrounding areas increases, as it is displaced rather than replaced. Nonetheless, pedestrianisation schemes are often associated with significant falls in local air and noise pollution and in accidents, and frequen ...

Ceteris Paribus
' (also spelled ') (Classical ) is a Latin phrase, meaning "other things equal"; some other English translations of the phrase are "all other things being equal", "other things held constant", "all else unchanged", and "all else being equal". A statement about a causal, empirical, moral, or logical relation between two states of affairs is ''ceteris paribus'' if it is acknowledged that the statement, although usually accurate in expected conditions, can fail because of, or the relation can be abolished by, intervening factors. chapter 2 A ''ceteris paribus'' assumption is often key to scientific inquiry, because scientists seek to eliminate factors that perturb a relation of interest. Thus epidemiologists, for example, may seek to control independent variables as factors that may influence dependent variables—the outcomes of interest. Likewise, in scientific modeling, simplifying assumptions permit illustration of concepts considered relevant to the inquiry. An example ...

Exurb
An exurb (or alternately: exurban area) is an area outside the typically denser inner suburbs, 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 area, urban and rural area, rural landscapes, holding a limited urban nature for its functional, economic, and social interaction with the city centre, 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. 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 ext ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Suburb
A suburb (more broadly suburban area) is an area within a metropolitan area. They are oftentimes where most of a metropolitan areas jobs are located with some being predominantly residential. They can either be denser or less densely populated than the city and can have a higher or lower rate of detached single family homes than the city as well. 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 world, English-speaking countries, suburban areas are defined in contrast to core city, 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 ...

Automobile Dependency
Car dependency is a pattern in urban planning that occurs when infrastructure favors automobiles over other modes of transport, such as public transport, bicycles, and walking. Car dependency is associated with higher transport pollution than transport systems that treat all transportation modes equally. Car infrastructure is often paid for by governments from general taxes rather than gasoline taxes or mandated by governments. For instance, many cities have minimum parking requirements for new housing, which in practice requires developers to "subsidize" drivers. In some places, bicycles and rickshaws are banned from using road space. The road lobby plays an important role in maintaining car dependency, arguing that car infrastructure is good for economic growth. Description In many modern cities, automobiles are convenient and sometimes necessary to move easily. When it comes to automobile use, there is a spiraling effect where traffic congestion produces the 'demand' for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
