A method of spatial shape layout of streets and alleys based on grid selection

Abstract

The invention discloses a street spatial form layout method based on grid selection. The street spatial form layout method includes the steps of generating a street grid reference system on basis of set grid form parameters; extracting present spatial form data from a vector diagram of a current street, superimposing the data onto the grid reference system, and conducting grid local rotation and deformation on the reference system according to the present form; setting a public center and an open space range, and conducting grid segmenting and merging; and conducting fine adjustment of the road width and form to form a final street spatial form layout. The invention achieves the overall logic and order of the spatial form layout through grid selection, and the operating method has the portability and is suitable for a variety of urban street layout design; and the invention has the advantages of flexible design, less time consumption, high efficiency, uniqueness and unduplicatedness of generated results, and so forth, and has a practical application value for planning engineering practice.

Description

technical field [0001] The invention relates to a method for layout of urban space form, in particular to a method for layout of street and lane space form based on grid selection. Background technique [0002] The layout of the spatial form of streets and alleys is the core link of urban planning and construction engineering practice, and it is also an important technical means of urban land management. In the context of rapid urbanization, fast, scientific and rational spatial form layout techniques are needed. With the rapid development and wide application of computer technology and information processing technology, conditions are provided for the realization of urban spatial form automatic layout. Grid layout, as a basic mode of urban spatial form organization, can be seen in various types of cities at all times and in all over the world, whether it is Miletus in ancient Greece, Timgad in ancient Rome, Chang'an in Tang Dynasty, Dadu in Yuan Dynasty, Middle Ages Paris,...

AI Technical Summary

Problems solved by technology

However, in the long process of urban development, the spatial form of streets and alleys is often affected by many factors. It is impossible to quickly sort out and analyze a large number of related influencing factors only by artificial thinking judgment, and at the same time, it is impossible to establish the spatial form scientifically and rationally only by subjective judgment. layout logic
