Urban business service facility layout rationality evaluation method and system considering crowd consumption characteristics

Abstract

The invention provides an urban business service facility layout rationality evaluation method and system considering crowd consumption characteristics, and the method specifically comprises the steps: obtaining the consumption demand index data of crowds with different characteristics; calculating a walking network distance between the community demand point and the commercial network point; determining a walking distance attenuation function; constructing and optimizing a double-constraint potential model considering group consumption characteristics; and establishing a comprehensive evaluation method according to the constructed double-constraint potential model considering the group consumption characteristics. On the premise of considering the influence of space blocking elements on the community walking reachable range, a double-constraint potential model of consumption characteristics of people of different ages is constructed, a comprehensive evaluation method is established, the influence of supply and demand differences on the spatial layout balance of the business service facilities is analyzed from the two aspects of business service facility supply and differentiated demands, the method and the system have very important significance in realizing the demand-oriented differential configuration of the urban commercial network points.

Description

technical field [0001] The invention relates to a method and system for evaluating the rationality of the layout of urban commercial service facilities in consideration of crowd consumption characteristics, in particular to the technical field of data relationship processing and analysis. Background technique [0002] Urban commercial layout is an important part of the overall layout of the city. In the field of urban commercial circulation, urban commercial layout is one of the most unbalanced and insufficient areas of urban development. The balanced evaluation of urban commercial service facilities is the key to optimizing urban commercial Preconditions for resource configuration. [0003] In the prior art, the traditional evaluation methods for the layout of urban commercial service facilities mainly focus on analyzing the urban commercial regional structure and commercial network layout, commercial center system, evolution trend, function type and centrality from the ove...

Problems solved by technology

[0004] The traditional evaluation method of urban commercial service facility layout based on the community life circle, whether it is to use the analysis method based on the Euclidean distance or the network distance when calculating the reachable distance between the facility point and the demand point, or to evaluate the commercial service facility configuration around the community In terms of balance, due to the failure of spatial elements such as railways, mountains, and rivers to block the coverage of facilities and the impact of community residents' differentiated needs on facility allocation, the evaluation results of the rationality of the allocation of commercial service facilities around the community are relatively rough
