After watching CaBi movies for two days a year apart, I wanted to visually compare them side by side. In the post A Day in the Life of Capital Bikeshare I show animations of CaBi traffic the day Saturday before the last two Thanksgivings. The movie below shows CaBi traffic from November 20, 2010 with yellow dots, and November 19, 2011 with white dots.

That Saturday in 2010 had 2,180 trips, and a year later grew 58% to 3,443. While the number of trips grew, the length of the average trip shrank, from 20.3 minutes in 2010 to 16.5 minutes in 2011. A histogram on the right compares the two years side by side, and in fact there are times when the 2010 traffic is greater. But overall, the pattern is largely the same. Like before, trips that begin and end at the same station are not shown.
