Red Light Camera Violations

This dataset reflects the daily volume of violations created by the City of Chicago Red Light Program for each camera. The data reflects violations that occurred from July 1, 2014 until present, minus the most recent 14 days. This data may change due to occasional time lags between the capturing of a potential violation and the processing and determination of a violation. The most recent 14 days are not shown due to revised data being submitted to the City of Chicago during this period. The reported violations are those that have been collected by the camera system and reviewed by two separate City contractors. In some instances, due to the inability the registered owner of the offending vehicle, the violation may not be issued as a citation. However, this dataset contains all violations regardless of whether a citation was actually issued, which provides an accurate view into the Red Light Program. Because of occasional time lags between the capturing of a potential violation and the processing and determination of a violation, as well as the occasional revision of the determination of a violation, this data may change.

本数据集记录了芝加哥市红灯摄像头项目（City of Chicago Red Light Program）下每台摄像头每日生成的交通违规记录总量。该数据涵盖2014年7月1日至今的违规行为，但剔除了最近14天的记录。由于潜在违规行为的抓拍与违规认定、处理之间存在时滞，本数据集可能发生变更；因近期14天内提交给芝加哥市的修正数据尚未完成整合，故暂不展示该时段的记录。本数据集收录的违规记录均已由摄像头监控系统采集，并经两名独立的市政承包商完成审核。在部分场景中，由于无法联系违规车辆的登记车主，相关违规可能不会被正式开具罚单，但本数据集包含所有已被抓拍的违规行为，无论是否实际出具罚单，以此完整呈现芝加哥市红灯摄像头项目的实际运行全貌。由于潜在违规抓拍与违规认定、处理之间存在时滞，以及违规认定结果可能会被后续修正，本数据集的内容可能发生变动。如需了解红灯摄像头项目的更多详情，可访问：http://www.cityofchicago.org/city/en/depts/cdot/supp_info/red-light_cameraenforcement.html。对应的超速摄像头违规数据集链接为：https://data.cityofchicago.org/id/hhkd-xvj4。
