I was considering to make a proposal for the next Google Summer of Code. Last summer I mentored the Public Transport Assistant plugin. I think it would be relatively easy to extend its functionality to foot and bicycle relations, so it becomes easier to validate and fix them. We'll see how it goes. With a fair bit of automation, it shouldn't be too hard to incorporate roundabouts and dual carriiage ways in those kinds of relations.
