Awesome. I hope SFMTA can learn from this. They are taking proposals to replace Nextbus currently [1]. When I last measured Nextbus reliability, the first prediction for a bus was weakly correlated with arrival, and the second and third predictions were totally free of information. One of the main problems around here seems to be buses with the route and destination sign set to the wrong thing (e.g. the bus says it is headed to downtown, it's actually going the other way) which apparently throws a huge wrench in Nextbus.
