Mark Patterson, a Carnegie Mellon graduate student studying social and decision sciences, took one massive data file and turned it into maps and graphs that detail different aspects of Pittsburgh’s bike-share system, Healthy Ride. In the bike-share’s opening three months, from June through August, Pittsburghers and tourists took about 40,000 rides combined, but Patterson wanted to see the intricacies. “Ultimately it works great on both sides,” says Patterson. “We get a fun opportunity to explore, and they get a chance for more insight.”
