[OSRM-talk] Project-OSRM: In need of advice; can offer some commercial support to you/ your projects in return

I'm writing this as an OSM mapper and user of the OSRM api, I'm not an OSRM
dev, so I might make some mistakes here.

The passability and driving speed of road types is determined by lua
scripts (see
for the example car script). So you can at least make one script per
vehicle type (split up your lorries in discrete types, and have a script
for every type).

Now, OSRM is suited, but I don't know if OSM data is suited. Lorry tagging
is something not many mappers do (not many mappers need maxweight or
maxlength properties of a way), so data may be sparse. But this depends a
lot on the region you're operating in. It's generally known that Europe has
better coverage than North America, but even in Europe such tagging will
depend a lot on the region you're in.

As for the return service you propose, if you use the data for truckers, it
would be great if you could get those truckers to help contribute data to
the database. In contrast to the average mapper, they will care about
maxweight and maxlength properties, and will want to correct those where
wrong. In turn, this also makes your data and your routes better.

It can be achieved by giving the truckers a training on how to add that
data to OSM, or give them some option to add notes to OSM (in which case
these notes will have to be interpreted by regular mappers, and mapped).
