NYC Taxis, Lyft, and Uber Ridership Graphs: Data from January 2015 to June 2018

Note: Green taxis and Yellow taxis have been added together under "Taxis". Lyft data begins in April 2015.

Trips Aggregated by Month:

Observations:

In November 2017 the number of monthly Uber trips surpassed that of Taxis

In May 2017 the number of monthly Uber + Lyft trips surpassed that of Taxis

Trips Aggregated by Week:

Note about x-axis: The date on the x-axis refers to the number of trips of that day plus the ones that occurred in the following 6 days (a total of 7 days): e.g. 04 Jan 2015 refers to the number of trips that took place within and including January 4 and January 10, 2015.

The weekly graph contains the same information as the monthly graph, however by aggregating the trips by a smaller timeframe we can see more volatility. This increased granularity allow us to observe more clearly the effect that certain events had on these mediums of transportation.
Following are a couple of interesting dates:

• January 4-5, 2018: A severe winter storm (also colloquially called 'Bomb Cyclone') hit New York City causing Gov. Andrew M. Cuomo to declared a state of emergency, in which restrictions on driving were placed.
• November 15-16, 2017: A large winter storm caught the city unprepared, and caused significant travel difficulties.
