Study on digital planning of rail transit-urban spatial analysis and network planning

为有效提升轨道交通前期研究工作的精准化、数智化程度,文章在阐述城市空间分析对轨道交通线网规划意义的基础上,提出采用地理分析、空间计量模型、时空大数据分析等数字化技术进行城市圈层及空间结构分析,以确定轨道交通线网规模、服务水平、线网架构、功能层次等的研究思路;然后以厦门市为例,对轨道交通线网规划与城市空间结构的相关性进行全方位、参数化研究,量化确定城市出行范围(即交通可达性)、建成区用地边界、出行空间结构,以便为轨道交通线网规划提供依据。研究结果表明,多元化、数字化的城市空间分析能够为轨道交通线网规划提供方向、框架、结构、功能等方面的指引及优化思路,推进数字化技术与轨道交通行业的高效融合。

To effectively improve the precision and digitalization level of early-stage research on rail transit,the article elaborates on the significance of urban spatial analysis for rail transit network planning,based on which it proposes to use digital technologies such as geographic analysis,spatial econometric models,and spatiotemporal big data analysis to analyze urban circles and layers as well as spatial structures,so as to determine research ideas such as network scale,service level,network architecture and functional hierarchy.Then,taking Xiamen municipality as an example,a comprehensive and parametric study is conducted on the correlation between rail transit network planning and urban spatial structure,quantifying the city's travel scope(i.e.traffic accessibility),built-up area boundaries and travel spatial structure,so as to provide a basis for rail transit network planning.The results of the research show that diversified and digitized urban spatial analysis can provide guidance and optimization ideas for the direction,framework,structure and function of rail transit network planning,and promote the high-efficient integration of digital technologies and the rail transit industry.
