Urban vitality

Gentrification is the process of changing the character of a neighborhood through the influx of more affluent residents and businesses. It is a common and controversial topic in urban politics and planning. Gentrification often increases the economic value of a neighborhood, but the resulting demographic displacement may itself become a major social issue. Gentrification often sees a shift in a neighborhood's racial or ethnic composition and average household income as housing and businesses become more expensive and resources that had not been previously accessible are extended and improved.

Overtourism is the congestion or overcrowding from an excess of tourists, resulting in conflicts with locals. The World Tourism Organization (UNWTO) defines overtourism as "the impact of tourism on a destination, or parts thereof, that excessively influences perceived quality of life of citizens and/or quality of visitor experiences in a negative way". This definition shows how overtourism can be observed both among locals, who view tourism as a disruptive factor that increasingly burdens daily life, as well as visitors, who may regard high numbers of tourists as a nuisance.

Jane Jacobs was an American-Canadian journalist, author, theorist, and activist who influenced urban studies, sociology, and economics. Her book The Death and Life of Great American Cities (1961) argued that "urban renewal" and "slum clearance" did not respect the needs of city-dwellers.

Modern architecture, or modernist architecture, was an architectural movement or architectural style based upon new and innovative technologies of construction, particularly the use of glass, steel, and reinforced concrete; the idea that form should follow function (functionalism); an embrace of minimalism; and a rejection of ornament. It emerged in the first half of the 20th century and became dominant after World War II until the 1980s, when it was gradually replaced as the principal style for institutional and corporate buildings by postmodern architecture. According to Le Corbusier the roots of the mouvement were to be found in the works of Eugène Viollet le duc.

Robert Moses was an American urban planner and public official who worked in the New York metropolitan area during the early to mid 20th century. Despite never being elected to any office, Moses is regarded as one of the most powerful and influential individuals in the history of New York City and New York State. The grand scale of his infrastructural projects and his philosophy of urban development influenced a generation of engineers, architects, and urban planners across the United States.

Charles-Édouard Jeanneret, known as Le Corbusier, was a Swiss-French architect, designer, painter, urban planner, writer, and one of the pioneers of what is now regarded as modern architecture. He was born in Switzerland and became a French citizen in 1930. His career spanned five decades, and he designed buildings in Europe, Japan, India, and North and South America. He considered that "the roots of modern architecture are to be found in Viollet-le-Duc".

A motor vehicle, also known as motorized vehicle or automotive vehicle, is a self-propelled land vehicle, commonly wheeled, that does not operate on rails and is used for the transportation of people or cargo.

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". It is also arguably a more sustainable urban settlement type than urban sprawl because it is less dependent on the car, requiring less infrastructure provision.

Mixed use is a type of urban development, urban design, urban planning and/or a zoning classification that blends multiple uses, such as residential, commercial, cultural, institutional, or entertainment, into one space, where those functions are to some degree physically and functionally integrated, and that provides pedestrian connections. Mixed-use development may be applied to a single building, a block or neighborhood, or in zoning policy across an entire city or other administrative unit. These projects may be completed by a private developer, (quasi-) governmental agency, or a combination thereof. A mixed-use development may be a new construction, reuse of an existing building or brownfield site, or a combination.

A public space is a place that is open and accessible to the general public. Roads, public squares, parks, and beaches are typically considered public space. To a limited extent, government buildings which are open to the public, such as public libraries, are public spaces, although they tend to have restricted areas and greater limits upon use. Although not considered public space, privately owned buildings or property visible from sidewalks and public thoroughfares may affect the public visual landscape, for example, by outdoor advertising. Recently, the concept of shared space has been advanced to enhance the experience of pedestrians in public space jointly used by automobiles and other vehicles.
