Research On The Comprehensive Accessibility Of Recreational Space In Shanghai Based On Rail Transit

With the continuous development of society and economy and the continuous improvement of production levels,people's pursuit of life has transformed into a higher demand for living.Against this background,the tourism industry has developed rapidly as a way to meet people's needs for a better life,One-day tour,parent-child tour,selfdriving tour and other characteristic tourism methods emerge endlessly.For urban residents,various attractions,parks,squares,and commercial blocks have formed a place of recreation and entertainment,that is,recreational space.The layout and development of regional recreational spaces have a great impact on the happiness of local residents.For this,the thesis takes 23 recreation spaces in Shanghai as the starting point,evaluates the development of each recreation space from the internal and external perspectives,and puts forward some optimization suggestions based on the research results.The thesis takes public welfare,playability,and geographical location as criteria,selects 23 recreational spaces in Shanghai as research objects,and uses modern information technology to obtain Shanghai's metro line and site data,recreational space boundary data,and related facility POI data.Improve the vector reachability algorithm through python language and Arc GIS platform,build transfer reachability algorithm that can add transfer time,make the reachability calculation on metro more accurate,and combine the grid reachability algorithm,fully utilizing the advantages and disadvantages of vector and grid algorithms,the traffic accessibility of the recreation space in the study area was calculated in combination with other modes of travel such as public transportation and walking.The overall spatial form of traffic accessibility was analyzed,and according to the different traffic availability of the recreation space.It can be classified into a certain category for classification and research,classify and assign recreational facilities according to tourism behavior,establish a certain range of walking buffers on the boundary of recreational space,calculate walking accessibility of recreational space,and accessibility to walking.The results are divided into subscore studies and overall studies,divided into certain levels,and analyzed.The current development status of walking accessibility in the same recreation space.Finally,we will combine walking and traffic accessibility into a comprehensive accessibility index,analyze the comprehensive accessibility development of the recreation space,and based on the research results,some suggestions for improvement are put forward.The main conclusions of this study are as follows:(1)In terms of traffic accessibility,the area ratio of each time zone in the recreation space is similar,and the proportion of the reachable zone within 30 minutes is between 5.79% and 7.12%.The area of the reach zone is between 46.37% and 56.95%.The traffic accessibility space form of the recreation space is various and can be summarized as the circle layer-tree structure,asymmetric circle layer-tree structure,elliptical axial structure and multicenter ring layer structure.(2)On the level of walking accessibility,there are imbalances in the development of different types of facilities in the recreation space.Based on their levels and scores,the walking accessibility of the recreation space can be divided into balanced high-value types,balanced low-value types,and uneven There are corresponding improvement measures for different types of recreational spaces.(3)In terms of comprehensive accessibility,Lujiazui has the highest score and Dishui has the lowest score.Recreational space is divided into three levels of excellent,average,and poor according to the score.There are 8 recreational areas in the research area at an excellent level,8 recreation spaces are at a general level,and 7 recreation spaces are at a poor level.(4)According to the results of comprehensive accessibility research,make certain improvements to the recreation space,and put forward four suggestions to balance the internal elements of recreation space,differentiate the development of recreation space,strengthen group development,and coordinate the development of regional recreation space.The overall development of regional recreation space development.This study starts from the accessibility of the internal and external levels of the recreation space,reveals the development differences between the interior and exterior of the recreation space,explores the deep-seated reasons behind this difference from the perspective of traffic conditions,geographical location,etc.The general mechanism of accessibility and formulated a series of suggestions for the development of Shanghai's recreational space according to the actual situation,further reducing the differences between the interior and exterior of the recreational space,and achieving the coordinated development of the regional recreational space,thereby enhancing the overall development level of the research area and realizing the residents' happiness index improve.
