Nice Ride has released their data on rentals from 2011. After seeing these maps of “route fluxes” from bike sharing systems around the world by Oliver O’Brien at the Suprageography blog, I just had to figure out how to make them myself.
I didn’t use Routino as Oliver did, but instead figured out a way to make ArcGIS Network Analyst do what I wanted (after a fair amount of data wrangling and lots of loading time). I’ll probably post more on that later.
Trip counts on each segment vary between 4 and 29,000. I restricted bike routes to roads with a speed limit under 40 mph. One drawback is that my road network did not include off-street trails (greenway, etc).
