Problems solved by technology

At present, most of the investigation methods of urban cognition follow the method of cognitive map, and cognitive map is considered to reflect the spatial cognition of a certain group of cities. It is difficult to quantify the urban image only from the perspective of environmental physical space. Analyzing the cognition of general and broad social groups makes it more difficult to reflect the urban cognition map under the background of new media and the Internet

Embodiment 1

[0081] In the traditional sense, the analysis and design process of urban space is biased towards the qualitative process, based on the traditional data and following the subjective cognition of the designer, which lacks rationality and scientificity. Today, new data obtained from online "crowdfunding" can not only expand public participation, but also drive planning and design through quantitative analysis methods.

[0082] like figure 1 As shown, the method for generating a city cognitive map in this embodiment uses network data for "crowdfunding" analysis, emphasizing the heuristic role of quantitative analysis, including the following steps:

[0083] 1) Form editing

[0084] First, within a given geographical range, determine the place names and road names in the research area, then edit the current CAD, add the city place name point elements, extract the line elements of the road center line, and then establish the block block surface elements according to the road line ...

Embodiment 2

[0161] This embodiment is an application example. Taking the urban area of ​​Wuning County, Jiujiang City, Jiangxi Province as the research object, the method of the above-mentioned embodiment 1 is practiced, and a new urban space cognition is proposed from the network point of view by using big data and small samples. The traditional urban image forms a complementary relationship and also improves the urban planning investigation system.

[0162] 1) Form editing

[0163] 1.1) Classify place names in Wuning County according to urban roads, landmark buildings / structures, sections, mountains, and water bodies, and collect important place names of the city (Wuning-like The number of place names in small towns is relatively small, and a full sample can be used to generate a list of place names), a total of 165 nouns were found, including 59 urban roads, 43 landmarks / structures, 41 lots, 5 water bodies, and 17 mountains , as shown in Table 1 below.

Abstract

A city cognitive map generating method based on an internet word frequency, comprising: determining, in a given geographical range, the place names and road names in a studied area, and establishing a place name table and a road name table; editing a CAD drawing of status quo of the studied area; capturing the value of a place name word frequency and the value of a road name word frequency in the studied area, assigning the value of the place name word frequency in the place name table and assigning the value of the road name word frequency in the road name table; connecting a processed CAD file with the established tables, respectively calculating the value of an intersection word frequency, the value of a road word frequency and the value of a block word frequency, and generating a city cognitive map of the intersections, roads and blocks; and generating, by means of a traffic cost calculation method, an optimum cognitive path between two points or multiple points, and offering an optimization proposal for the studied area in combination with the cognitive map of the intersections, roads and blocks. The city cognitive measurement collected on the basis of the network data can provide new fundamental technical support for the planning and designing of the city physical form.

Description

technical field [0001] The invention relates to a method for generating a city cognitive map, in particular to a method for generating a city cognitive map based on Internet word frequency, and belongs to the field of generation of cognitive maps. Background technique [0002] With the deepening of globalization, networking, and informatization, as well as the continuous changes in transportation and communication, the way citizens acquire the cognition of urban space elements has also changed. The perception of urban space can no longer rely on the traversal of the real physical environment. The rapid dissemination of information has changed the way people obtain data. Under the massive, high-speed, diverse and valuable new data, it is necessary to analyze the characteristics of spatio-temporal behavior in the new era. offers the possibility. At present, most of the investigation methods of urban cognition follow the method of cognitive map, and cognitive map is considered...
