Where to find bike sharing systems' data feeds

Bike sharing systems by Bixi publish information about how many bikes and docks are available at each station about every minute, as XML or JSON.

People sometimes ask me where the feed is for this data, as it’s not always advertised on their website. Here are the feeds for all the systems so far:

XML feeds:

JSON feeds:


Washington State University’s Green Bike system has an unfortunate situation where the availability data is embedded in the source of their homepage (near the end).

I’ve found that there are some irregularities in the feed format, and sometimes it changes without notice. It may have stabilized now though.

Happy hacking!

Day 4: Processes vs threads, and kernel modules! Day 5: I wrote a kernel module!!!
