Spatial accessibility analysis method and device based on public facility differences

Abstract

The invention discloses a spatial accessibility analysis method based on public facility differences. The method comprises the following seven steps of: 1) obtaining population and service requirement data in a service area; 2) obtaining public facility data; 3) carrying out traffic and distance calculation on the service area; 4) determining the effective service range of a public service facility; 5) carrying out functional analysis on different levels of public facilities; 6) calculating the spatial accessibility value of the public service facility; and 7) carrying out the difference analysis on a spatial accessibility result. A device used for the analysis method comprises an on-site data collection terminal and a remote data processing platform. By use of the method and the device, the hierarchy and the maneuverability of an analysis result are improved. Compared with the traditional method, the method more approaches to a realistic situation, is more favorable for a planning and construction department to evaluate the spatial configuration situation of the existing public facility, provides decision support for the layout regulation and planning of the public facility, and is convenient in carrying out classified guidance on the planning and the construction of the public facility.

Description

technical field [0001] The invention relates to a spatial accessibility analysis method and device based on the difference of public facilities, and belongs to the technical field of layout design and evaluation of public facilities. Background technique [0002] The rational allocation of public facilities space is an important embodiment of social equity. The spatial location, distribution, function, and service scope of public facilities affect the convenience and fairness of access to these public facilities by people in need. Therefore, precise calculations are required to fully and effectively meet the needs of public facilities when designing and evaluating the layout of public facilities. Use needs and improve the comprehensive utilization rate of public facilities. To solve this problem, it is usually analyzed by using the spatial accessibility value. When analyzing the spatial accessibility value, the current analysis is mainly by using the mobile search method. Y...

The spatial location, distribution, function, and service scope of public facilities affect the convenience and fairness of access to these public facilities by people in need. Therefore, precise calculations are required to fully and effectively meet the needs of public facilities when designing and evaluating the layout of public facilities. Use needs and improve the comprehensive utilization rate of public facilities. To solve this problem, it is usually analyzed by using the spatial accessibility value. When analyzing the spatial accessibility value, the current analysis is mainly by using the mobile search method. Yes, this analysis method can effectively meet the needs of actual work to a large extent, but at the same time there is a phenomenon that there is a large deviation between theoretical calculations and actual conditions, and it is concentrated in: Differentiate the functions of the facilities, and think that all public facilities are only different in the quantitative indicators of supply capacity, ignoring the differences in the functions of public facilities, and can only generally examine the comprehensive accessibility value of public facilities, and cannot distinguish The accessibility of public facilities classified by different functions reduces the resolution of the analysis results and the ability to describe the real situation, thus failing to meet the needs of the urban planning department for the guidance and planning of public facilities by classification; The method for setting service thresholds ignores the differences in service scopes caused by differences in the scale and level of public facilities. For example, the service and radiation scopes of community parks and country parks are obviously different, and different thresholds should be used to describe their service scopes

The existence of these problems leads to a large deviation between the theoretical analysis and the actual situation, which cannot guide the layout design of public facilities well. Therefore, to solve this problem, it is urgent to develop a spatial accessibility analysis based on the difference of public facilities method to meet the needs of current practical use
