Police-Reported Road Traffic Crashes in Bogota, Colombia, 2014-2022

This dataset is part of the ESCALA (Study of Urban Health and Climate Change in Informal Settlements in Latin America) project that was funded by the Lacuna Fund of the Meridian Institute https://lacunafund.org/. This dataset contains police-reported collisions in Bogota, Colombia between 2014-2022, provided by the Secretaria de Movilidad de Bogota. The data included agregated data at collision level from the Secretaria de Movilidad de Bogota, as well as data about the vehicles and victims involved. For the preprocessing of this dataset several columns from the agregated data were deleted as it was considered that the data contained no useful information for the current study. Additionally undefined domains in variable COLOBJTYP were merged into a single value named 'unknown.' The files include a geographic information systems (GIS) shapefile with the latitude and longitude coordinates of each collision, as well as a tables with information about the victims and vehicles involved, linkable to the GIS file and to each other. The only preprocessing required for this data included comparing the ID_COL attribute from this dataset with the ID_COL attribute from the collision dataset- It was found that all ID_COL in the present data is also present in the collision data.本数据集隶属于ESCALA项目（拉丁美洲非正规住区城市健康与气候变化研究，Study of Urban Health and Climate Change in Informal Settlements in Latin America），该项目由子午线研究所拉库纳基金（Lacuna Fund of the Meridian Institute，https://lacunafund.org/）资助。本数据集包含哥伦比亚波哥大市2014至2022年间警方上报的交通事故数据，由波哥大交通局（Secretaria de Movilidad de Bogota）提供。数据涵盖波哥大交通局提供的事故级聚合数据，以及涉事车辆与受害者的相关信息。在本数据集的预处理流程中，由于部分聚合数据列对当前研究无实用价值，已将其删除。此外，变量COLOBJTYP中的未定义类别已被合并为统一值"unknown（未知）"。数据集文件包含记录每起事故经纬度坐标的地理信息系统（GIS，Geographic Information Systems）形状文件，以及可与该GIS文件及彼此关联的涉事车辆与受害者信息表格。本数据集仅需完成一项预处理操作：将本数据集的ID_COL属性与事故数据集的ID_COL属性进行比对，经核查发现本数据集内的所有ID_COL均存在于事故数据集当中。
