My usual use case for public transport is getting off the plane and into a busy station. Nearly every ticket system on first use, bar London and Tokyo, have ended up with me at the head of a queue of locals rolling their eyes to heaven. In these situations navigation to an end point as fast as possible regardless of $1 discrepancies in the ticket fair is the most important thing. I just keep hitting the forward/continue button until a price and a place to pay appears. Applying this use case to the Bart system, I would make sure that the bottom two buttons are always prev/next page in the navigation towards the end point of getting some form of a ticket and that they don't switch modes at any stage.



I just finished my final UI design project at UC Berkeley's School of
Information (I'm a grad student there) and was hoping for your
feedback.

We redesigned the BART ticket kiosk.

Our goal was to make it easier for first-time or infrequent riders to
use while not making it any harder for experienced riders. The
software was built in Adobe Flex; the physical prototype was built
around a laptop and controlled by an Arduino micro-controller.
