成渝地区双城经济圈县域便利使用公共交通人口比例数据集（2020年）

2020年成渝地区双城经济圈县域便利使用公共交通人口比例数据集，该数据集详细描述了2020年成渝地区双城经济圈县域内便利使用公共交通的人口比例。通过整合公共交通POI数据(包括公交、地铁站点，客运站点)和行政区划数据，确定公共交通站点的位置和其覆盖范围。采用了1公里缓冲区分析方法，将每个公共交通站点周围的区域定义为高可达区域，即便利使用公共交通的地区。并进一步结合了worldpop人口数据，计算每个区域内实际能便利使用公共交通的人口数量与比例。所有数据均以矢量格式保存，保证了数据的空间精度和可操作性。该数据为公共交通可达性和使用率的研究提供了的数据支持，为进一步优化公共交通网络和提高利用率提供了重要参考数据。

County-level Public Transit Accessible Population Proportion Dataset of Chengdu-Chongqing Twin-City Economic Circle in 2020. This dataset details the proportion of population with convenient access to public transit at the county level within the Chengdu-Chongqing Twin-City Economic Circle in 2020. By integrating public transit POIs (including bus, subway stations and passenger transport hubs) and administrative division data, the locations and coverage areas of public transit stations are determined. A 1-kilometer buffer analysis method is adopted, where the area surrounding each public transit station is defined as a high-accessibility area, i.e., a region with convenient public transit access. Furthermore, WorldPop population data is incorporated to calculate the actual population and proportion of people who can conveniently access public transit within each region. All data is stored in vector format, ensuring the spatial accuracy and operability of the dataset. This dataset provides data support for studies on public transit accessibility and utilization rate, and offers important reference data for further optimizing public transit networks and improving their utilization efficiency.
