Hello list!

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.

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
(www.routeware.dk), used a MSSQL database and was written in VB6.
Migration to VB.NET was planned when I left the company.

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!

I have been reading the AND data integration topic.

I see a lot of navigation ready attributes are still waiting to come in
to OSM, but that is a good thing!

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.

- A question for Lex Tiekink; is information about turn-restrictions
also available in the AND data?
- Is there a list that describes the relation between roadspeed and RD_TYPE?
- In what unit is RD_TONNAGE? in kilograms? I can imagine this value is
used to prevent trucks to pass small bridges
- How are (for instance) viaducts that are too low for trucks to pass
modelled?

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?

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?

Currently; WMS is no longer available on the OSM servers. are there
intentions to get it back up again? Or do you need help?
