Support for "Avoid-Area" or "Avoid-Obstacle" feature

[capiscuas]

Does pgrouting support this already?

I'd like to construct something like this site does:  http://seamster.cs.umd.edu:8090/map/index.html

which is to allow me to add dinamically some obstacles in the map and recalculate the ROUTE avoiding that parts. An approach to this could be the "Traffic problem paradigma" where I can assign a high WEIGHT to certain ways of my map (those with obstacles) and that way the system would choose an alternative route.

Hi, I suppose this is not meant as a ticket but as a question, so the forum ( http://pgrouting.postlbs.org/discussion ) would be the better place to ask this question.

To give a short answer: this is feature that already exists. You can take actually everything as "cost" and you can "mix" your costs as you like (use SQL queries for that). And if you want to exclude certain areas completely, just exclude them in your query.
