Transportation Network Providers - Vehicles

All vehicles reported by Transportation Network Providers (sometimes called rideshare companies) to the City of Chicago as part of routine reporting required by ordinance. Inclusion of a vehicle in a monthly report indicates that the vehicle was eligible for trips in Chicago in that month for at least one day, regardless of whether it actually provided any rides. If a vehicle is eligible in multiple months, which is common, it will have records in each of these reporting months.

As of the creation of this dataset, there have been four TNPs licensed to operate in Chicago, although never more than three at any given time and currently three. Vehicles reported by more than one company in the same month are combined and the MULTIPLE_TNPS column is marked as TRUE. However, the matching process is imperfect so not all such vehicles are necessarily identified.

Information on last inspection date was not required before September 2017 so will not be found in older records.

The reporting is done on a monthly basis, as indicated in the MONTH_REPORTED column. However, starting in 2018, the reports are batched and files for all three months in a quarter are delivered to the City of Chicago at the end of each quarter. Due to an issue in this transition, some vehicle records for Q2 2018 (April-June) were reported for the quarter as a whole, rather than for individual months. For purposes of this dataset, those records have been assigned to 2018-06 (June). Therefore, some caution in interpreting this month and the quarter as a whole is advised.

本数据集收录了交通网络提供商（有时亦称作共享出行公司）根据芝加哥市法规要求进行的常规报告提交的所有车辆信息。每月报告中的车辆录入，意味着该车辆在当月至少有一天具备在芝加哥执行行程的资格，无论其是否实际提供了出行服务。若车辆在多个月份具备资格，这在实际情况中较为常见，则其记录将分别出现在这些报告月份中。至本数据集创建时，共有四家TNPs（交通网络提供商）在芝加哥获得运营许可，但任何时刻不超过三家，目前为三家。同一月份内由多家公司报告的车辆将被合并，并在“MULTIPLE_TNPS”列中标记为TRUE。然而，匹配过程并不完美，因此并非所有此类车辆都能被识别出来。在2017年9月之前，关于最后一次检查日期的信息并非报告要求，因此不会出现在较旧记录中。报告按月进行，如“MONTH_REPORTED”列所示。然而，自2018年起，报告被批量处理，每个季度的所有三个月的文件将在每个季度末交付给芝加哥市。由于过渡期间的问题，2018年第二季度（4月至6月）的一些车辆记录作为整个季度的报告，而不是按月报告。因此，在解读本月份和整个季度时需谨慎。
