Source Code

The I Bike KNX app is based on previous works in Philadelphia and Atlanta. It is based on an open-source application called CyclePhilly, developed by volunteers at CodeForPhilly and extended by Cycle Atlanta. CodeForPhilly's efforts were based on the original CycleTracks application developed by the San Francisco County Transportation Authority in 2010:

Source code for iOS and Android versions of the Knoxville Region's implementation of the app is available on Github. Phillip Goldfarb and Mark Bellott developed updates to the user interface, app security and compatibility.

What is does

The I Bike KNX app uses your smartphone’s GPS to record information about your bicycle trips. When you start the app, information about the route you take is recorded, along with the speed and time of day. Optional information including the purpose of your trip can be specified. When you complete your trip, the data is sent to the Knoxville Regional Transportation Planning Organization where it will be aggregated with hundreds of other trips to build a picture of the routes most frequently used to travel in the area.
