Abstract

The invention discloses an urban street space vitality simulation method and system, computer equipment and a storage medium. The method comprises the following steps: acquiring a map image in a research range; creating street line elements, drawing a street network on the map image, and generating street road segment line elements; generating facility point elements, and inputting distance screening facility point elements influencing street vitality; generating a neighbor table of facilities and streets; generating street intersection elements; constructing a facility-street intersection ODtable to obtain street network distances between all facilities and two intersections of all streets; calculating the average vitality of all streets to obtain a street vitality table; generating a current street vitality grid and a planned street vitality grid; and generating a comparison grid of planning and current street vitality. The urban current street vitality can be simulated, the plannedstreet vitality can be simulated according to planning requirements, and the planning effect can be predicted by comparing the current street vitality with the planned street vitality.

Description

technical field [0001] The invention relates to an urban street space vitality simulation method, system, computer equipment and storage medium, and belongs to the fields of urban and rural planning technology and building technology. Background technique [0002] Streets are places that carry the most diverse types of public functions in urban physical space, and are also an important medium for organizing various functions of the city. The vitality of street space includes the interweaving process of human activities and living places, which reflects the diversity of urban life and is an important reflection of urban vitality. Therefore, street vitality is an element to examine the effect of urban planning implementation, and it is an important issue in the field of urban planning. Among the various factors that determine the vitality of street space, the most prominent are the attractiveness of the street environment and functions. With the emergence of Internet big dat...
