SAT阅读素材:Modern urban design

　　Modern urban design can be considered as part of the wider discipline of Urban planning. Indeed, Urban planning began as a movement primarily occupied with matters of urban design. Works such as Ildefons Cerdas General Theory of Urbanization , Camillo Sittes City Planning According to Artistic Principles , and Robinsons The Improvement of Cities and Towns and Modern Civic Art , all were primarily concerned with urban design, as did the later City Beautiful movement in North America.

　　Urban design was first used as a distinctive term when Harvard University hosted a series of Urban Design Conferences from 1956 . These conferences provided a platform for the launching of Harvards Urban Design program in 1959-60. The writings of Jane Jacobs, Kevin Lynch, Gordon Cullen and Christopher Alexander became authoritative works for the school of Urban Design.

　　Gordon Cullens The Concise Townscape, first published in 1961, also had a great influence on many urban designers. Cullen examined the traditional artistic approach to city design of theorists such as Camillo Sitte, Barry Parker and Raymond Unwin. He created the concept of serial vision, defining the urban landscape as a series of related spaces.

　　Jane Jacobs The Death and Life of Great American Cities, published in 1961, was also a catalyst for interest in ideas of urban design. She critiqued the Modernism of CIAM, and asserted that the publicly unowned spaces created by the city in the park notion of Modernists was one of the main reasons for the rising crime rate. She argued instead for an eyes on the street approach to town planning, and the resurrection of main public space precedents, such as streets and squares, in the design of cities.

　　Kevin Lynchs The Image of the City of 1961 was also seminal to the movement, particularly with regards to the concept of legibility, and the reduction of urban design theory to five basic elements - paths, districts, edges, nodes, landmarks. He also made popular the use of mental maps to understanding the city, rather than the two-dimensional physical master plans of the previous 50 years.

　　Other notable works include Rossis Architecture of the City , Venturis Learning from Las Vegas , Colin Rowes Collage City , and Peter Calthorpes The Next American Metropolis . Rossi introduced the concepts of historicism and collective memory to urban design, and proposed a collage metaphor to understand the collage of new and older forms within the same urban space. Calthorpe, on the other hand, developed a manifesto for sustainable urban living via medium density living, as well as a design manual for building new settlements in accordance with his concept of Transit Oriented Development . Bill Hillier and Julienne Hanson in The Social Logic of Space introduced the concept of Space Syntax to predict how movement patterns in cities would contribute to urban vitality, anti-social behaviour and economic success. The popularity of these works resulted in terms such as historicism, sustainability, livability, high quality of urban components, etc. become everyday language in the field of urban planning.
