[OSGeo-Discuss] Remote routing solutions

We've actually also just kicked off an open source routing engine 
project, attempting to collaborate with all the open source trip 
planners we knew about at the time.

See http://opentripplanner.org/

We're working with Brandon of GraphServer, as well as the developers of 
Five Points (see http://new.atltransit.com/), One Bus Away (which has a 
trip planner) and ByCycle.org

Focused on multi-modal, to replace the routing engine at 
http://ride.trimet.org/ (currently the only proprietary piece of their 
whole map).  Though we might also have a bike routing use case soon.

Steven - it'd be great to collaborate in some way: if it's too late to 
collaborate on code we could at least build a common API.  In time we're 
hoping to establish a nice library of transit specific GeoExt type 
components.  So people could easily use OpenLayers and Ext.js to compose 
a transit map like Portland's.  It'd be great if those components could 
talk to the same routing API, and indeed could be the start of an 
improved open standard.

best regards,
