WARNING ! You should be aware that this docker image is very crude and I'm only using it for a personal pet project. Still, it might help you by providing a basic working prototype.
This is a simple pre-baked docker image of OpenTripPlanner, containing:
- OSM data for railway stops/stations + highways in 1km surrounding of mentioned stops/stations
- railway GTFS routing data for Czech Republic.
The image can be used as a standalone "batteries included" REST API server which you can use for
- searching for routes between railway stations/stops
- generating Isochrone vector layers from a specific station (ie. map overlay showing how far you can get in 1,2,3,4,5 hours..)
The image is based on urbica/docker-otp and uses the gtfscr/GVD2022 scripts to prepare fresh GTFS data off a rather non-standard format of czech railway timetables.
I'm running this image successfully (under very small load!!!) on a 2GB RAM VPS magine, which also run a few more containers of my pet project application.
At the moment, I'm using a JAVA_OPTIONS=-Xmx1500m environment property for my OTP container. This value currently seems to be a reasonable minimum amount of heap that the OTP server needs for this custom-tailored czech-republic routing graph.
Currently the building is splitted into 2 steps:
01_build_osm.sh
- fetches OSM data for Czech Republic
- filters the data, so that only roads & railway-related information is retained for faster processing
- uses overpass api to only retain road network in close proximity of railroad stops
- the final step which downloads the overpass query can take ~15 minutes (on XPS13 9370 laptop, ie Intel(R) Core(TM) i7-8550U)
02_build_otp.sh
- uses pre-built output of
01_build_osm.sh - uses
brdloush/GVD2022scripts to download recent railroad routing timetables & converts them to GTFS - builds a standalone docker image containing OpenTripPlanner + routing data (+ roads in proximity of stops)
docker run --rm -it -p 8081:8080 -e JAVA_OPTIONS=-Xmx1500m brdloush/otp-czech-railway --serve --loadOnce started, you can lookup stops (docs here):
