Sounds great.

Regarding GPS data, perhaps this is something Mapbox would be interested in somehow processing. I think they’ve already worked on using GPS data to adjust speed estimates in OSRM for cars. They’re also working on extending OSRM so dynamic traffic data can be used to update the routing suggesting in near real-time.

Hi Sander & Emil,
Thanks for the quick responses. The usage of the lua script is particularly useful.

I completely respect the limitations of the demo server and can offer to set up another server to support the project. 20Tb of traffic should help?

I've been following the discussions on the OSM forum and they've discussed the quality of the map to a great extend.
For planning purposes I appreciate that the main source of error is delay in updates. To counter that we are planning to use our commercial help-desk to collect information from drivers about detours and unrecorded obstacles so that OSM can get the updates with less than a days delay. We can also track some vehicles, and capture information such as slowdown caused by traffic jams, etc. on major roads. Hopefully this can become a valued source of information?

If somebody has a burning interest in accelerating this, then please feel free to get in touch for a sponsorship.
That's the least I can do.

Kind regards

My name is Bjorn, and I'm the director at a commercial project that needs something like the Open Source Routing Machine with Openstreet Map where you both appear rather active. You can find a little bit about me on linkedin<https://uk.linkedin.com/in/bmadsen> and Multi-Agent Technology<http://www.multiagenttechnology.com/> London.

Question: The most pressing question I have is whether OSRM is suitable for truck/lorry routing in its current state?

The passability and driving speed of road types is determined by lua scripts (see https://github.com/Project-OSRM/osrm-backend/blob/develop/profiles/car.lua 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.

I have no need to visualize the map data. Only calculation of the path, length and duration of the route for heavy goods vehicles for planning purposes. This means that I need to check for constraints such as weight, low bridges and width-limitations along the path.

If queries are as quick as on the demo-server for the osrm-project, then time is on our side. In my lack insight, I imagine that this can be done in iterations, where first a path is chosen for cars, which subsequently is inspected for these constraints. If constraints are detected, alternatives will need to by discovered. I'm sure you have better ideas?

The demo server is what it is, a demo. If you want truck routing, you'll have to install your own server with your own profiles.

I'm also on Google hangout (using this email) if you'd prefer to talk instead of writing longer emails.

Thanks again for getting back to me.

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).
