Hi Henrik and Steve,

About Navteq data:
It's for sure one of the major network data sources ... but it's not
available in Japan, where Anton and I (the ones, who wrote most of the
documents) live and work. I think that's the reason, why there isn't more
information available. We used Navteq sample data a bit out of interest, but
didn't spend very much time with it.
We would appreciate though if someone would volunteer to add some "How to
use pgRouting with Navteq) information to the pgRouting website. The new
website source files are in a Github repository:
https://github.com/pgRouting/website. Anyone, who wants to add some content
will get write access to it (Just send me your GitHub account username). The
website is automatically updated from the repository every hour.
If this sounds too complicated, you can just write to the Wiki:
https://github.com/pgRouting/website/wiki and I will then add it to the
website.

You can define a list of ID's to apply restrictions to multiple edges. As
Steve mentioned, there might be other ways to implement this, but we're a
bit short on contributors (and of course on financial contribution ;-)
