New York City is home to millions of people who rely on its robust transportation system. The taxi system in particular plays a critical role in helping people navigate the city. With access to information about every single trip that occurred in a yellow taxi in 2013, we were able to reveal patterns in how people move throughout the city. We also analyzed driver efficiency, showing that there is a substantial amount of skill involved in driving a taxi, with some drivers consistently earning up to 30% more than average. Finally, we used the highly granular nature of this data to identify the locations of redundant trips in the city, and showed that a simple carpooling strategy could reduce the amount of times money spent on taxis as well as the number of taxi trips taken by upwards of 7%.
