Re: [OSRM-talk] maxspeed and speeds in car.lua HELP
Thank you for your answer. I have been changing the speeds in the car.lua profile and routing between different points with different distances. I have found that, for longer routes if I reduce all the speeds of the profile, there is a noticeable difference in the travel times, but it is not the same for shorter distances. From reading the code, I don't understand this behaviour, can someone point out possible causes? Longer Route: http://localhost:5000/route/v1/driving/-2.130661,52.586363;-1.506500,52.408284?steps=true=true=full=geojson Medium Route: http://localhost:5000/route/v1/driving/-1.823924,52.560484;-1.897888,52.481578?steps=true=true=full=geojson Small Route: http://localhost:5000/route/v1/driving/-1.823924,52.560484;-1.897888,52.481578?steps=true=true=full=geojson *Longer Route * *distance (Km)* *time (min)* at original speed 59.6 60 at 2/3*speed 58.4-60.5 66-73.4 at 1/2*speed 58.4-60.7 71.4-78.8 at 1/3*speed 58.6-58.4 78-79 *Medium Route* *distance (Km)* *time (min)* at original speed 11.6-12.4 15.6 at 2/3*speed 11.6-12.4 16-19 at 1/2*speed 11.6-12.4 16.3-20 at 1/3*speed 11.6-12.4 17-20 *Small Route* *distance (Km)* *time (min)* at original speed 0.338-0.387 50.3-64.9 at 2/3*speed 0.338-0.387 50.3-64.9 at 1/2*speed 0.338-0.387 50.3-64.9 at 1/3*speed 0.338-0.387 50.3-64.9 Thank you.

[OSRM-talk] maxspeed and speeds in car.lua
Hi everyone, I would like to have your input regarding this: In OSM there is tag: maxspeed. In my case, I find that the majority of the primary roads have 30mph ~ 48 kph as a max speed. In the car.lua, I find that the highway speed that has been set primary is 65 kph. Is the speed in the OSM tag taken into consideration? I understand that the speed table is accessed by WayHandlers.speed() function but I am not sure what's the effect of WayHandlers.maxspeed(). Thank you for your help! ___ OSRM-talk mailing list OSRM-talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/osrm-talk
[OSRM-talk] OSRM support for third-party data API version.
Hi, Does the latest OSRM supports integrating third party raster data? If so, with what api_version? I am trying to reproduce the steps in the wiki: https://github.com/Project-OSRM/osrm-backend/wiki/Integrating-third-party-raster-data using api_version 1 but I get the following: [info] Raw input contains 5324037 nodes, 783034 ways, and 0 relations, 0 > restrictions > libc++abi.dylib: terminating with uncaught exception of type > osrm::util::exception: There are no edges remaining after > parsing.src/extractor/extractor.cpp:645 > Abort trap: 6 > I appreciate any ideas on this! ___ OSRM-talk mailing list OSRM-talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/osrm-talk

It worked, thank you!

Re: [OSRM-talk] Docker pre-processing from a python script
Thank you for the suggestion. however I get :
/usr/local/bin/docker: Error response from daemon: OCI runtime create
failed: container_linux.go:344: starting container process caused "exec:
\"osrm-extract -p /opt/car.lua /data/berlin-latest.osm.pbf\": stat
osrm-extract -p /opt/car.lua /data/berlin-latest.osm.pbf: no such file or
directory": unknown.
I do have data/berlin-latest.osm.pbf in the working directory. Also, could
you explain what "%s:/data" does exactly?
Thank you

[OSRM-talk] Docker pre-processing from a python script
Hi all,
I would like to run the pre-process of the car profile from a python
script. I have checked the documentation of subprocess library and docker
SDK for python but I don´t know how to properly make the request. For
example, how could I transform the sh request:
docker run -t -v "${PWD}:/data" osrm/osrm-backend osrm-extract -p
/opt/car.lua /data/berlin-latest.osm.pbf
So it can be done from python. Is that possible?
Thank you in advance
