Study on site selection and layout planning of public toilets in urban comprehensive park: Taking xuanwu lake park in Nanjing as an example

Abstract

Reasonable location and layout of public toilets can ensure the use efficiency of toilets in the park, and improve the use experience of tourists and satisfaction with the park. (1) Based on the background of "tourism toilet revolution", this paper summarizes the existing methods to solve the problem of facility location, and analyzes the possibility of facility location in urban park. (2) This paper summarizes the single constraint conditions of the existing facilities location, less considering the flow of people and other issues, proposes and establishes a multi-level, multi constraint condition location model. (3) The optimization model proposed in this paper is applied to the location and layout of public toilets in Xuanwu Lake Park, Nanjing. (4) The location model proposed in this paper can meet a variety of constraints at the same time, and provide a more convenient, scientific and economic location method for urban park public toilets and other infrastructure services, landscape buildings, and provide reference for other types of urban park landscape building facilities location.
