I'm looking for initiatives pursuing mobile offline trip planning using a combination of public transit data and walking-routes. Thus far, without much success.

Osmand, seems to be closest, but the part for offline tripplanning isn't completely funded yet. I may contribute, but haven't got a clue about its viability.

I'm looking for any projects pursuing this, or papers (comfortable with reading the academic math-stuff) outlining this. Also roadblocks preventing this (or rather: making quick implementation unlikely), etc. welcome of course.

I'm 'only' looking to do offline trip planning within one city at a time, which obviously brings down complexity lot.

P.S: adapted question from question posted on opentripplanner-forum: https://groups.google.com/forum/?fromgroups=#!topic/opentripplanner-users/m6PGVRBA0eU

Are you looking for Open Source solutions or are commercial products (aka Nokia Maps API 'offline' mode) –  Mapperz Dec 14 '12 at 21:43

What about rrrr and brouter (Mainly for bike routing. But supports car and walking. Maybe usefull as an idea for data format). Web interface to brouter. Brouter is slower because it is possible to use different profiles for routing on the fly without precalculations. (race bike, moped, doesn't like sidewalks, loves steep hills etc)

I think Rrrr currently support only Public transport. About Rrrr

I think Rrrr can be used as an OTP sever because API is the same, but it is possible for it to run on a mobile phone. Whole public transport data for Netherlands is 20 MB.

There are some people bridging Rrrrr and OTP. See post

So maybe use Rrrr for public transport part and brouter or for other parts. Or maybe just brouter data format which is also quite compact.
