As announced on the OpenGeo blog and at SFpark.org, all the components of San Francisco’s innovative parking space management system are now open source — and they’ve gone out of their way to make it re-useable by other cities.

Here’s what SFpark does in a nutshell: it ties together sensor-based real-time data about parking space availability, smartphone applications to make that information available (yes, have your passenger use it), and flexible demand-sensitive pricing, all with the goals of minimizing the number of cars circling around looking for parking and maximizing the efficiency of space usage. 

You can check out the server-side code, the Android smartphone client code, the iPhone client code, and there’s a Ruby library put by Code for America too.  It’s all under open source licenses.

But they’ve done a lot more than just release code.  They’ve also put out a 134-page book, SFpark: Putting Theory Into Practice — Post-launch implementation summary and lessons learned, which summarizes SFpark’s experiences as of August 2011, just after their first rate adjustment.  The book is meant to be “a resource to those studying parking policy as well as cities considering new parking policy and technology”.  There are also maps, images, screenshots, documents on meter rate adjustments, and many other things available from their resources page.

The SFpark FAQ pages are a good place to start, if you’re intrigued by what you’ve read here.  Congratulations to the SFpark team and to OpenGeo!
