<br>
Sorry, the implementation that I have is was developed for a specific client and is very much tied to their data and table structure and I am not allow to distribute it.<br>
<br>
I have written up how to do this on a wiki page here:<br>

Hello, Daniel.<br>
<br>
Thank you for your quick reply. Well, for now I wouldn't want to enrol<br>
myself in such an endeavor :) . I would prefer to use something that is<br>
already done, even if it is much simpler than other routing engines'<br>
driving instructions.<br>
I was reading one thread of your mailing list where you guys talk about<br>
the solution presented by Stephen Woodbridge, using iMapTools, and I was<br>
wondering if Stephen's algorithm is accessible for use, or if it is a<br>
private solution.<br>
<br>
Do you know anything about this subject? Thank you very much.<br>
<br>
Regards,<br>
<br>
Paulo.<br>

Greetings.<br>
<br>
I am a portuguese developer and I just started using pgRouting<br>
as my routing engine. I chose it because it is very flexible and<br>
scalable, and it is based on a relational database.<br>
<br>
This offers me other types of functionalities that normal<br>
routing engines don't.<br>
<br>
Even so, I need a higher-level functionality, namely route<br>
instructions or navigation directions, that pgRouting does not<br>
provide for now (I think).<br>
<br>
I read some forum posts from people that had the same problem as<br>
me. Some of them are really old (more than 2 years). I found two<br>
ways of doing that:<br>
<br>
- One way is to implement a instruction algorithm, such as<br>
the one described here:<br>
<a href="http://lists.osgeo.org/pipermail/pgrouting-users/2011-January/000537.html" target="_blank">http://lists.osgeo.org/<u></u>pipermail/pgrouting-users/<u></u>2011-January/000537.html</a><br>
<br>
- The other way is to have an external service to do that,<br>
such as, <a href="http://techbase.kde.org/Projects/Marble/RoutingInstructions" target="_blank">http://techbase.kde.org/<u></u>Projects/Marble/<u></u>RoutingInstructions</a><br>
<br>
Now, my question is that neither one of the approaches to having<br>
navigation directions from a pgRouting route is optimized or<br>
well documented.<br>
<br>
Are there any new alternatives to these two approaches? If not,<br>
is there a more developed solution to the route instructions<br>
issue (commonly called Driving Directions issue) ?<br>
<br>
<br>
Hi Paulo,<br>
<br>
As you have already said, this question came up quite a few times<br>
already.<br>
I think the reason, why there is no out-of-the-box solution yet, is,<br>
that it is very difficult (probably impossible) to provide this kind<br>
of driving instructions in a way that it works for any (road) network.<br>
And beside the variety of data there are also lots of languages.<br>
<br>
If you (or someone else) is able to draft a concept how to produce<br>
driving directions in a smart way, that it does not depend on a<br>
specific dataset or language, then such a functionality would be a<br>
valuable contribution ... which might even attract some funding ;)<br>
<br>
Regards,<br>
Daniel<br>
