I'm also using Navteq data, it feels good to that I'm not alone with<br>
pgrouting and navteq since the documentation is about navteq + pgrouting<br>
is almost non-existent.<br>

My colleagues and I are trying to figure how to update the rules for the<br>
shooting star algorithm to use driving restrictions. Any hints?<br>

Hi Henrik,<br>
<br>
This is a problem area in my mind. Look in the list archive for "turn restrictions" I have posted about this in the past.<br>
<br>
To summarize:<br>
<br>
1. it is my opinion that we need to revamp how restrictions are defined in pgRouting and I have made some proposals, but we have not had any development resource that have had time to implement it<br>
<br>
2. there some ability to enter turn restrictions when you add an edge if I recall. In theory, if you have multiple restrictions you have to add the edge multiple times one with each restriction. I haven't actually tried to do this so I'm not sure if or how well that works.<br>
<br>
3. I'm not sure if you can add a complex restriction that requires multiple edges to define.<br>
<br>
Hope this helps,<br>

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.</div>
<div>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: <meta http-equiv="content-type" content="text/html; charset=utf-8"><a href="https://github.com/pgRouting/website">https://github.com/pgRouting/website</a>. 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.</div>
<div>If this sounds too complicated, you can just write to the Wiki: <meta http-equiv="content-type" content="text/html; charset=utf-8"><a href="https://github.com/pgRouting/website/wiki">https://github.com/pgRouting/website/wiki</a> and I will then add it to the website.<br>
