Problems solved by technology

The method of comprehensive index evaluation and analysis and questionnaire is highly subjective. The spatial analysis method using GIS mainly depends on the spatial distribution of barrier-free facilities, and the evaluation of barrier-free facilities is not systematic and comprehensive.

Embodiment 1

[0144] The following takes a street park square as an example to describe the method of calculating the urban barrier-free facility index in detail. like Figure 1-3 As shown, a method for evaluating the Residential Area-to-Park Plaza Accessibility Service Index includes the following steps:

[0145] S1. Import the obtained spatial data such as park square and public green space, community area data, population point data, and barrier-free public facility data into a file geographic database.

[0146] S2. Screen out the population data of age 60 and above and persons with disabilities who meet the conditions of barrier-free facilities, divide the residential area into multiple 1000m*1000m grids, and summarize the total population in each grid. The quantity is matched to its corresponding grid according to the spatial position and stored.

[0147] S3. According to the range of the residential area grid, circle the buffer area of ​​the activity range with a radius of one kilom...

Abstract

The invention discloses a method for calculating an urban barrier-free facility index. The method comprises the following steps: S1, acquiring data; S2, carrying out grid processing on the resident area; S3, selecting a barrier-free facility supply cardinal number in the residential area grid; S4, using a 'behavior observation method' to measure the use frequency of various facilities; S5, calculating the weight of each evaluation factor based on an analytic hierarchy process; S6, calculating the supply amount of the barrier-free facilities; S7, calculating a global barrier-free facility service index and a local barrier-free facility service index; and S8, counting and summarizing barrier-free facility service indexes. By calculating the barrier-free facility service indexes of urban public places such as urban roads, public buildings and park squares, the comprehensive service level of the barrier-free facilities in the urban public places is reflected, and the degree of urban barrier-free environment construction is reflected.

Description

technical field [0001] The invention relates to a method, in particular to a method for calculating an index of urban barrier-free facilities, and belongs to the technical field of geographic information systems. Background technique [0002] Most of the barrier-free facilities are attached to other public infrastructures, which are large in number, small in granularity, scattered in location, and highly variable, making it difficult to obtain and update data. The coverage and standardization of barrier-free facilities are inconsistent. There are many existing problems in barrier-free facilities, which affect the overall service level of barrier-free facilities. The main means of data acquisition for barrier-free facilities are questionnaires or experience evaluation, and most of the evaluation indicators are qualitative. It is highly subjective, it is inconvenient to guide maintenance and construction, and the discovery and acquisition of problems with barrier-free faciliti...
