This video (best watched in high-definition (HD 720p)) shows all the bicycle trips made in one day in Chicago’s Divvy bicycle-share system, 2013. Each circle represents a Divvy bicycle station. Larger circles indicate a greater number of trips beginning and ending at that station. The color of the circle indicates the proportion of trip arrivals and departures: yellow means more arrivals, pink means more departures, and white means an equal mix of both. Watch the pattern of colors in the morning rush hour.

The number of arrivals and departures at each station was calculated for every five-minute interval of the day and was averaged over the number of days that the station was active in 2013.
