Yes, OSRM can be used for truck routing. You can easily modify the LUA profile,
which determines what ways are routable and at what speed, based on OSM tags.

The default car profile computes fastest route. If you modify it to use the

Keeping speed and impedance separate is not an easy task.

The OSRM project includes a set of cucumber tests that does a lot of testing of
binaries, including preparing data and querying the server. It’s ruby based but
maybe it can help you. Look in the folder features/. The various support files
that queries osrm are in features/support/

Yes it’s possible by first combining pbf files with osmosis. Osmosis supports
polygons files with mutliple polygons, in case you want to start with a pbf
file that covers all of north america and then filter that to just leave
specific areas.

In your lua file, first get the highway tag:
local highway = way.tags:Find("highway")
Then chech the value and either return false to completely ignore the way,
or return a low speed to make it unattractive, but still passable.
If you just want to modify the file profiles/car.lua, you can simp

Hi Elisabeth,
Great that you will want to help improve OSRM!
Do you mean that you will not touch the routing algorith, and just provide an
elevation profile of the route? Or do you also want to change the routing

Intel recently released a preliminary version of Clang with full OpenMP 3.1
support: http://lists.cs.uiuc.edu/pipermail/llvmdev/2013-August/065169.html.
This means it should now be possible to compile OSRM with OpenMP on Mac. Of

Of course it would be easier if OSRM supported several profiles out of the box.

On a sidenote, I think the way.direction flag could be removed from LUA.

There are no way to tag this. But OSRM has a penalty for doing u-turn.

the current implemenation does no grouping of signals.
