There's some prior work in OpenTripPlanner - 
http://blog.openplans.org/2012/06/b-roll-david-solves-the-plaza-problem-with-help-from-de-berg-and-matt-conway/ 
.   The odd cases come up quickly when there is a convex or concave area 
and deciding when to traverse it.

   I'm not sure if that work was rolled up into the current 
OpenTripPlanner repository though.
