Data Challenge


Explore the data to see how Chicago gets around by bike!

The Challenge

The submission period for the 2015 Divvy Data Challenge is now closed. Please check back for information on how you can vote on the finalist entries and attend our awards ceremony.

To celebrate the first time Divvy trip data for an entire year (more than 3.2 million trips!) had been made publicly available, we encouraged all scientists, designers, students, civic minds, planners, and programmers to analyze and present this data in visually compelling ways.

We asked for visualizations that help us illustrate the answers to questions such as: Where are riders going? When are they going there? How far do they ride? What are top stations? What interesting usage patterns emerge? What can the data reveal about how Chicago gets around on Divvy?

Past winners of the 2014 Divvy Data Challenge can be viewed here.
