Chicago Taxi Trips
This dataset contains the 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.

Description
Chicago residents and visitors took more than 27 million taxi rides in 2015, traveling 83 million miles and spending more than $400 million.
The City of Chicago assures the quality and safety of those rides through its Department of Business Affairs & Consumer Protection (BACP). We have long published the taxi drivers and vehicles licensed by BACP on the Chicago Data Portal.
Taxi trips are not reported in real time. Each trip appears long after the completion of the ride. Therefore, the dataset cannot be used to track trips in motion or even just-completed trips. By the nature of how the data are collected, reported, and processed, a minimum of a few days will pass between completion of a ride and its appearance in the dataset. More typically, the delay will be anywhere from a week to a month.
Each row in the dataset describes a distinct taxi trip and shows:
– Which taxi provided the trip
– What times the trip started and ended
– Length of the trip in both time and distance
– Starting and ending Community Area — plus Census Tract for many trips
– Fare amount and other components of the trip cost
– Type of payment — such as cash or credit card. (As an important note, cash tips are not included in the data because they do not go through the payment systems.)
Taxi company.
Although taxi rides take place on the public streets and can be freely observed, the start that there could be privacy issues in publishing them. Implemented a number of measures to preserve privacy while not unduly hampering use of the data. These measures include the following.
Delay:
Taxi trips are not reported in real time. Each trip appears long after the completion of the ride. Therefore, the dataset cannot be used to track trips in motion or even just-completed trips. By the nature of how the data are collected, reported, and processed, a minimum of a few days will pass between completion of a ride and its appearance in the dataset. More typically, the delay will be anywhere from a week to a month.
Masking of Taxi Medallion Number:
Each licensed Chicago taxi has a license number, indicated by the Illinois license plate number, a painted number on the body of the taxi, and the medallion on the taxi’s hood. The Taxi ID in this dataset is not that license number. It is created specifically for this dataset, with no external meaning, to allow users to determine rides provided by the same taxi but not which taxi.
Masking of Time:
Analysis of taxi trips by time will be a major use of this dataset and significant value will be added for understanding the taxi industry and travel in Chicago. However, there is minimal value and some potential privacy cost in making it possible to find a specific trip that someone knows departed at 10:13 am. To balance these issues, all start and end times to the nearest 15 minutes has been rounded.
Masking of Location:
From where and to where people travel is, of course, the most basic information about taxi trips and expected to be the topic of much analysis. However, as with exact time, exact location down to the street address could affect privacy. Therefore, location is only provided at the Census Tract and Community Area levels.
Since some Census Tracts have relatively infrequent taxi trips, we show the Census Tracts of a trip only if both the starting and ending Census Tracts had at least three trips in the relevant 15-minute time period. Because of this rule, about 1/4 of Census Tracts that would otherwise be shown are blank. (Others are blank because of missing data or falling outside Chicago.)
