Research On Metro-based Accessibility Of Leisure Facilities In Shenzhen

Urban leisure space is the main place for residents’ interaction,leisure and other activities.It plays an important role in organizing urban public life and improving the living quality of residents.Under the trend of people-oriented,residents are increasingly concerned about the convenience of participating in various leisure activities and the availability of leisure facilities.Therefore,research on accessibility has become an important way to promote the allocation of urban public resources,especially the study of leisure facilities’ accessibility based on public transportation,which helps encouraging residents to use public transportation to join leisure activities.It plays an important role in promoting the sharing of urban leisure resources and the equity of space.In recent years,the rapid development of rail transit has brought an opportunity for the adjustment of urban spatial structure.The use of rail transit to organize the layout of urban leisure facilities and promote the coupling between rail transit and accessibility of leisure facilities has become an important proposition in planning practice.This paper studies the spatial accessibility of leisure facilities in Shenzhen based on the mode of rail transit,and reveals the differences in spatial configuration of leisure facilities resources.Using the rail transit network to build a database of residents’ travel,adopt an improved two-step mobile search method to measure the accessibility.Through setting different thresholds and distance attenuation coefficients for different levels of leisure facilities,calculate the accessibility of different types and levels of leisure facilities to describe difference characteristics and comprehensive accessibility measures for leisure facilities.From the perspective of space,time and crowd,the division of administrative districts is used to explore the service circle that can obtain leisure resources in different time thresholds.From the time dimension,analyze the change of accessibility of leisure facilities in different construction stages.Using the traffic data of rail transit,establish the spatial connection between the leisure travel behavior space and the accessibility of leisure facilities,empirically test the potential accessibility measure,and analyze the coupling relationship between leisure travel behavior and leisure material space.The research shows that the accessibility of municipal leisure facilities based on rail transit is unevenly distributed in different administrative regions,and the accessibility of district-level leisure facilities is relatively balanced.Superimposed analysis of the accessibility of municipal leisure facilities,showing an obvious “cold spot” area in the eastern part of Luohu district.The third stage of trail transit construction has a significant impact on the accessibility of leisure facilities,which clearly reflects the fairness of the accessibility of leisure facilities in space allocation.The leisure travel behavior space and leisure space accessibility of residents are relatively consistent in the overall trend.For the coupling relationship between facility accessibility and leisure travel behavior,this paper analyzes five typical types of areas,in order to provide some constructive countermeasures and suggestions for the planning and layout of leisure facilities in Shenzhen,and the optimal allocation of rail transit in the context of intensive and refined urban development.
