[OSM-dev] Open Social Routing Idea: Request for preliminary comments

[Gregory]

It sounds good.
Anyone who knows about routing knows that it takes a crazy long time to be
sure of the perfect route. This could be a way for the program to say "I
know the best way to get most of the way, because Jane told me she goes this
way.".
Adding a load of sample routes in one area, and with a good weighting on
provided routes, it would be interesting to see how the program faired to
other routing algorithms that.

Are you going to look at motoring routing? Walking routing might be just as
interesting (and more easy to get people's routes added). I walk around
university a lot, sometimes two routes look exactly the same length but I
take the route through a park because it's nicer and makes the journey feel
shorter. Sometimes I go one way because it just has a few steps, returning I
go another way because it's downhill.
