Taxi Trips - 2014

Note: As discussed in http://dev.cityofchicago.org/open%20data/data%20portal/2019/07/01/taxi-dataset-relaunch.html, some trips in November-December 2014 are known to be missing. --Taxi trips reported to the City of Chicago in its role as a regulatory agency. To protect privacy but allow for aggregate analyses, the Taxi ID is consistent for any given taxi medallion number but does not show the number, Census Tracts are suppressed in some cases, and times are rounded to the nearest 15 minutes.

Due to the data reporting process, not all trips are reported but the City believes that most are.

请注意：如http://dev.cityofchicago.org/open%20data/data%20portal/2019/07/01/taxi-dataset-relaunch.html所述，2014年11月至12月期间的部分出租车行程数据存在缺失。该数据集反映了芝加哥市作为监管机构所收到的出租车行程报告。为保护隐私并允许进行汇总分析，出租车标识符（Taxi ID）对于任何特定的出租车牌照号码保持一致，但并未显示具体号码；在某些情况下，人口普查区（Census Tracts）被匿名化处理，时间信息则被四舍五入至最近的15分钟。由于数据报告流程的限制，并非所有行程都被记录，但芝加哥市相信大部分行程已得到报告。更多关于此数据集及其创建方式的信息，请参阅http://digital.cityofchicago.org/index.php/chicago-taxi-data-released。关于本数据集中隐私保护方法的进一步讨论，请参阅http://dev.cityofchicago.org/open%20data/data%20portal/2019/04/12/tnp-taxi-privacy.html。有关2019年7月数据集发生的重大变更的讨论，请参阅http://dev.cityofchicago.org/open%20data/data%20portal/2019/07/01/taxi-dataset-relaunch.html。
