Before we only worked on subsequent quick turns, as in: `right, right` keeps the user on the rightmost lanes. This changeset modifies the logic to work on any subsequent steps that are "quick" and have lane information we can constrain later. Because we do not have a from-lane => to-lanes mapping we take the lanes left and right of the turn lanes into account when heuristically assigning the leftmost / rightmost lanes. There are some edge cases where this still does not give us the optimal solution but it gets close to what is actually possible at the moment without having a lane mapping in post-processing.

Building
For instructions on how to build and run OSRM, please consult the Wiki.
To quickly try OSRM use our free and daily updated online service
Documentation
Full documentation
Quick start
Building OSRM assuming all dependencies are installed:
mkdir -p build
cd build
cmake .. -DCMAKE_BUILD_TYPE=Release
cmake --build .
sudo cmake --build . --target install
Loading preparing a dataset and starting the server:
osrm-extract data.osm.pbf -p profiles/car.lua
osrm-contract data.osrm
osrm-routed data.osrm
Running a query on your local server:
curl http://127.0.0.1:5000/route/v1/driving/13.388860,52.517037;13.385983,52.496891?steps=true&alternatives=true
Running a request against the Demo Server
First read the API usage policy.
Then run simple query with instructions and alternatives on Berlin:
curl https://router.project-osrm.org/route/v1/driving/13.388860,52.517037;13.385983,52.496891?steps=true&alternatives=true
