OTP setup for VBN
There is not just one way to do it. That is why you have the following selection.
Prepare host system
- Set up Java
- Download JRE
- Copy JRE onto host system like this:
scp -P 22 ~/OpenJDK11U-jre_x64_linux_hotspot_11.0.12_7.tar.gz sib@83.223.94.182:/home/sib/
- Move and extract archive like this:
sudo mv ~/OpenJDK11U-jre_x64_linux_hotspot_11.0.12_7.tar.gz /opt/
sudo tar -xzf OpenJDK11U-jre_x64_linux_hotspot_11.0.12_7.tar.gz
- At JAVA_HOME to
~/.bashrc
like this: export JAVA_HOME=/opt/jdk-11.0.12+7-jre
- Extend PATH in
~/.bashrc
like this: export PATH=$PATH:$JAVA_HOME/bin
- Test JAVA version like this:
java -version
Upload OTP onto host system
Donload JAR archive. You find more details in the Basic Tutorial Copy JAR archive from Maven directory onto host file system like this.
scp -P 22 ~/otp/otp-2.0.0-shaded.jar sib@83.223.94.182:/home/sib/otp/
Copy config files from git repo onto host file system like this.
scp -P 22 otp-setup/vbn/build-config.json sib@83.223.94.182:/home/sib/vbn/otp/
scp -P 22 otp-setup/vbn/otp-config.json sib@83.223.94.182:/home/sib/vbn/otp/
scp -P 22 otp-setup/vbn/router-config.json sib@83.223.94.182:/home/sib/vbn/otp/
Setup according to basic tutorial
- Download GTFS data from Connect-Fahrplanauskunft GmbH
- Download osm map data from geofabrik
- Get bounding box for VBN from https://boundingbox.klokantech.com/
- csv:7.6966,52.4508,9.6501,53.8503
- Extract VBN map data using the tool
osmconvert
creating the file cd ~/vbn/otp/
osmconvert lower-saxony.osm.pbf.ln -b=7.6966,52.4508,9.6501,53.8503 --complete-ways -o=vbn.osm.pbf
- The output file is called
vbn.osm.pbf
- Build a street graph with OSM and elevation data only (ignoring transit input files)
java -Xmx5G -jar otp.jar --buildStreet .
- The output file is called
streetGraph.obj
- Build a graph layering transit data on top of the saved street graph (built using the previous command)
java -Xmx5G -jar otp.jar --loadStreet --save .
- The output file is called
graph.obj
- Copy config files to the right place like this:
tbd
- Finally, the server can be started using the --load parameter
- java -Xmx5G -jar otp.jar --load .
Setup accoriding to cookbook
There is a dedicated [repository[(https://github.com/transportkollektiv/digitransit-setup) for this cookbook.

Lessons Learned
Setting both MEMORY
and GRAPH_BUILD_MEMORY
to 4 GB and running the instruction docker-compose --env-file=.env.vbn up --build -d
on a computer with 8 GB total and 4 GB memory available results in the following error.
