Abstract: | In order to make a reasonable evaluation of the accessibility of the urban rail transit network, this paper studied the evaluation method and index selection. Based on the spatial syntax theory and accessibility theory, the paper used Depthmap to analyze the syntactic variables of line network spatial characteristics, and evaluated the accessibility of Shenzhen rail transit planning line network from four indicators of global integration degree, local integration degree, comprehensibility degree and spatial intelligence degree. The results show that with the continuous improvement of the rail network, the global and local integration indicators have increased, the intelligibility and spatial intelligence indicators have decreased, and the city has gradually developed from the urban core area to the direction of multiple regions, multiple centers, and multiple clusters. The urban morphology and structure have developed rapidly, and the accessibility between groups has been continuously enhanced. |
