<p class=MsoNormal style='margin-bottom:12.0pt'><span style='font-family:"Helvetica","sans-serif"'>Hello
list!<br>
<br>
I am Milo van der Linden from the Netherlands, a talk-nl member for some time
now. We have been talking the AND data for a while now.<br>
<br>
I have a history in advanced routing. I was the lead developer on a GIS system
with routing mechanism for creating drivetime analyses for the dutch
firebrigades. This mechanism routed from up to 90 vehicles per region to up to
200000 locations to determine if firetrucks arrived within the service level,
based upon mapinfo as an OLE object, rwnet (<a href="http://www.routeware.dk">www.routeware.dk</a>),
used a MSSQL database and was written in VB6. Migration to VB.NET was planned
when I left the company.<br>
<br>
On the talk-nl list we have been talking about routing with OSM data. I get the
feeling that with the embracing of AND this comes into clear sight! A big hail
for AND!<br>
<br>
I have been reading the AND data integration topic.<br>
<br>
I see a lot of navigation ready attributes are still waiting to come in to OSM,
but that is a good thing!<br>
<br>
I can see that road-direction is based on FNODE ->TNODE, when the
drawing direction is unreliable, for routing, a check should be done if drawing
starting node equals FNODE, if not, the sequence of points should be flipped.<br>
<br>
- A question for Lex Tiekink; is information about turn-restrictions also
available in the AND data?</span><span style='font-family:"Helvetica","sans-serif";
color:#1F497D'><o:p></o:p></span></p>
<p class=MsoNormal style='margin-bottom:12.0pt'><span style='font-size:11.0pt;
font-family:"Calibri","sans-serif";color:#1F497D'>Yes, turn restrictions are
available in the data.<o:p></o:p></span></p>
<p class=MsoNormal style='margin-bottom:12.0pt'><span style='font-family:"Helvetica","sans-serif"'>-
Is there a list that describes the relation between roadspeed and RD_TYPE?</span><span
style='font-family:"Helvetica","sans-serif";color:#1F497D'><o:p></o:p></span></p>
<p class=MsoNormal style='margin-bottom:12.0pt'><span style='font-size:11.0pt;
font-family:"Calibri","sans-serif";color:#1F497D'>No, there is no standard list
available. Every company that uses AND data for routing makes their own route
planning algorithm based on various attributes in the AND data. It’s a
matter of interpretation and fine-tuning. <o:p></o:p></span></p>
<p class=MsoNormal style='margin-bottom:12.0pt'><span style='font-family:"Helvetica","sans-serif"'>-
In what unit is RD_TONNAGE? in kilograms? I can imagine this value is used to
prevent trucks to pass small bridges</span><span style='font-family:"Helvetica","sans-serif";
color:#1F497D'><o:p></o:p></span></p>
<p class=MsoNormal style='margin-bottom:12.0pt'><span style='font-size:11.0pt;
font-family:"Calibri","sans-serif";color:#1F497D'>In tons.<o:p></o:p></span></p>
<p class=MsoNormal style='margin-bottom:12.0pt'><span style='font-family:"Helvetica","sans-serif"'>-
How are (for instance) viaducts that are too low for trucks to pass modelled?</span><span
style='font-family:"Helvetica","sans-serif";color:#1F497D'><o:p></o:p></span></p>
<p class=MsoNormal style='margin-bottom:12.0pt'><span style='font-size:11.0pt;
font-family:"Calibri","sans-serif";color:#1F497D'>These restrictions are not
modelled.</span><span style='font-family:"Helvetica","sans-serif"'><br>
<br>
Since roadclass plays a role, would it be a thing to enhance OSM with
transportation-type tables that contain valuable attribute for specifics
methods of traveling?</span><span style='font-family:"Helvetica","sans-serif";
color:#1F497D'><o:p></o:p></span></p>
<p class=MsoNormal style='margin-bottom:12.0pt'><span style='font-size:11.0pt;
font-family:"Calibri","sans-serif";color:#1F497D'>I don’t see this as
part of the map data, but part of the route planning algorithm (and software).<o:p></o:p></span></p>
<p class=MsoNormal style='margin-bottom:12.0pt'><span style='font-family:"Helvetica","sans-serif"'>On
the talk-nl, we have been talking about setting up a development team to take
our first steps in navigation; currently we have different flavours of
developers; would it be a good thing to start a global development group to
implement so/dll C++ libraries for routing?<br>
<br>
Currently; WMS is no longer available on the OSM servers. are there intentions
to get it back up again? Or do you need help?<br>
