Hi Julian, This is a very interesting idea - truth-checking the timetables against the actual journey times.
My main concern is that you don't want one person to have a bad journey home on a slow bus, and then the whole map changes, making people decide not to buy a house'/set up a business in that whole part of town because of one aberrant bit of data. There are people who have data you could use with the volume required for bad data to be ruled out - the bus GPS systems themselves, mobile phone companies, even transport passanger surveys. Or maybe it is time to launch an OSM style project for voluntarily gathered transport performance data - data that isn't owned exclusively by someone intent on wringing all the cash out of it in their own pockets. In fact, here's an idea. A voluntarily installed mobile app that only shares your location data when you appear to have taken some sort of public transport along a known route, between known nodes.
