Police-Reported Road Traffic Crashes in Barranquilla, Colombia, 2016-2022

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 Road traffic collisions recorded by the police from 2016 to 2022. These data were from the Agencia Nacional de Seguridad Vial (ANSV) of Colombia. (1)There are collision events with no information for some attributes such as COLZONE, COLOBJ, COLOBJTYP. (2) Each event has three hypotheses about its cause, but the latter two are mostly blank or repeat the first hypothesis. The following preprocessing errors were identified:(1) Data cells with no information were filled with NA, (2) Columns with the second and third collision hypotheses were removed as they were redundant with the first hypothesis.

本数据集隶属于ESCALA（拉丁美洲非正式定居点城市健康与气候变化研究，Study of Urban Health and Climate Change in Informal Settlements in Latin America）项目，该项目由子午线研究所（Meridian Institute）旗下的拉库纳基金（Lacuna Fund）资助，资助方官网为https://lacunafund.org/。本数据集收录了2016年至2022年间警方记录的道路交通事故碰撞事件，数据来源于哥伦比亚国家道路安全局（Agencia Nacional de Seguridad Vial，ANSV）。(1) 部分碰撞事件的部分属性存在信息缺失情况，如COLZONE、COLOBJ、COLOBJTYP。(2) 每起事件均配有三项成因假设，但后两项大多为空或与第一项假设内容重复。经排查，本次数据集存在以下预处理问题：(1) 无有效信息的数据单元格已填充为NA；(2) 鉴于第二、第三项碰撞成因假设与第一项存在冗余，已将对应列予以移除。
