Have a good week-end,

Some folks have written Python wrappers around libosrm, like here:
https://github.com/ustroetz/python-osrm
but I've never tried them, so I don't know how up-to-date they are, or how
easy they will be to get working.
If you're comfortable in NodeJS, then OSRM supports Node bindings as a
first-c
Technically it is possible (for example
https://stackoverflow.com/questions/145270/calling-c-c-from-python),
but I'm pretty sure that you will need to create sort of c++ envelop,
shared lib, etc.. It would be easier just to do what you need in c++
instead of python.

thanks Sasha. And do you know if it's possible to do calls to libosrm
functions directly from Python?

There are lot of examples of how to make python things in parallel
threads. For example:

Maybe this will help you: http://www.liedman.net/leaflet-routing-machine/

Dear all,
Under the option steps=true, osrm returns the detailed list of turn by turn
steps along the itinerary.
Does any tool already exist that can understand and display such
information?

Thanks Daniel. My first idea was to break my list into sets and running the
job on different machines as you said in 4).
But out of curiosity, can I make calls to libosrm.a functions directly from
Python?
And are you aware of some python code that would do the calls to
osrm-routed in parallel threa
Patrick,
There are about a million possible paths you could take here, a lot of it
will depend on what skills you have available. Off the top of my head:
1) Speed things up by avoiding HTTP overhead and calling the libosrm.a
functions directly instead of hitting `osrm-routed` over HTTP

It is not mandatory. Just fast
Ok I found some explanations about libosrm here:
https://github.com/Project-OSRM/osrm-backend/blob/master/docs/libosrm.md
My second questions remains though: is libosrm mandatory for parallel use?
or could I use osrm-routed too (even if it is slower)?
All my code is written is Python so it could be
Sorry for the newbie question but what's the difference between osrm-routed
and libosrm? Is it mandatory to use the latter for a parallel usage? And do
you have an example of code that does the calls in parallel threads? Thanks
Sasha for your help.

Hi Patrick,
If you are using libosrm (which reported to be thread safe:
https://github.com/Project-OSRM/osrm-backend/issues/4966) you can just
split your list and run its parts in different parallel threads.

Very interesting, thanks Bryan. Unfortunately, the requirement about Stata
is probably a downer for us.

I want to call the map matching service for nearly a million of routes. I
calculated that the task could take 10 hours on my laptop to complete. I
was wondering if there's someone who faced the same problem and who
addressed it in parallel, maybe with Spark? Another tool or way?
