there really needs to be a configurable rules/decisions engine. I.e. i would prefer to walk everywhere, i will take public transit if it saves me more than 15 minutes total or 5 minutes per leg, evaluate this at every interchange node.
There are some routings in london for example where the best course of action is actually to take a train, get off walk 5 minutes then take a different train, google will always tell you to stay on the train to a point where you can change trains in the same station.
