Problems solved by technology

However, while this method simplifies calculations, it also introduces errors that are inconsistent with reality, including: (1) equating the needs or characteristics of the population of the smallest research unit, thinking that they have the same demand preference (degree) for certain public facilities, Ignoring their differences, a one-size-fits-all approach treats the population of the smallest research unit as a whole. It can only examine the comprehensive accessibility value of the smallest research unit to public facilities, and cannot describe the impact of different characteristics of the population in the research unit on public facilities. Accessibility situation, which reduces the resolution of the analysis results and the ability to describe the real situation

Embodiment

[0079] Example: Take the accessibility calculation of parks in Jiaozuo City as an example:

[0080] 1. Overview of the research area: This study takes the downtown area of ​​Jiaozuo as the research area, with an area of ​​about 80 km2, including four administrative districts: Jiefang District, Zhongzhan District, Macun District, and Shanyang District. The population of the study area is about 779,900, and the total area of ​​park green space is 659.1265 hectares. Citizens' daily travel methods include walking, bicycles, electric vehicles and private cars, and public buses are mainly public transport vehicles.

[0081] 2. Data acquisition:

[0082] (1) Population data: 1) Population data: In this example, the street is taken as the smallest population unit, and the population data of each street is counted based on the census data. At the same time, this example takes the location of the street office of each street as the center of the street, and records its location inform...

Abstract

The present invention relates to a method and device for analyzing the spatial accessibility of public facilities in consideration of user characteristics. For traffic travel mode, the research unit constrained only by the spatial location is further divided into groups of different characteristics, and then the accessibility values ​​of public facilities are calculated for different groups of characteristics, which is conducive to analyzing public facilities from more perspectives and deeper levels. Spatial accessibility of facilities. In the process of calculating the accessibility of different groups of people, the service range of the park or the spatial range of people visiting the park under different traffic modes are calculated and fitted by using the surveyed and statistical travel time of residents to the park, which avoids the empirical method to determine the space The subjectivity brought by the range, so as to obtain the evaluation of the spatial accessibility of public facilities that is closer to the reality, and describe the rationality of the spatial distribution of public facilities more accurately.

Description

technical field [0001] The invention relates to surveying and mapping science and technology, in particular to a space accessibility analysis method, in particular to a public facility space accessibility analysis method considering user characteristics. Background technique [0002] The rational allocation of public facilities is an important manifestation of social equity. The spatial location and distribution of public facilities affect the convenience and fairness of people in need to visit these public facilities. This convenience can be analyzed with the help of spatial accessibility analysis method. Spatial accessibility analysis methods include: proportional method, shortest distance method, potential method and other methods. Among them, the two-step mobile search method based on the potential method is the most commonly used. This method not only considers the proximity of the demand crowd and public facilities, but also introduces the interaction between the cro...
