Today, I’ve been working on some station statistics. From the trip data, I calculated incoming and outgoing trips per station as well as the station’s first day of operations. Combining this information makes it possible to calculate the average day’s “bike balance”. A balanced station has the same number of incoming and outgoing trips while an unbalanced station will either run out of bikes or empty slots for returns.
I’ve published the resulting station map on QGIS Cloud (http://qgiscloud.com/anitagraser/hubway_cloud1) where you can have a look at the bike balance values.
Additionally, I’ve created a mashup in Leaflet pulling together background tiles from Stamen and the cloud-hosted WMS for better orientation:
