The purpose of this repository is to visualize planned maxspeed and other road changes with their consequences on routing/navigation and thus on traffic volume.
For this 2 OSRM instances will be started with original and modified data. For the modification the 2 OSRM Profile directories will be used
The current *osrmBprofiles containes modifications to cap maxspeed to 30 in case of
maxspeed:type=DE:urban
or
zone:traffic=DE:urban
Installation
Fetch yourself an PBF file of OSM data an run "prepare"
./prepare guetersloh-latest.osm.pbf \
profiles/osrm-default/car.lua \
profiles/osrm-clampto30-zone-de-urban/car.lua
which will create 2 Docker volumes containing the different data.
Then run
docker-compose -f compose.yaml up
Usage
After starting the docker container point your Browser to
http://localhost:8080
Click on the map for "Start" and "Endpoint". You'll see routes coming up where the green one is result from OSRM A and red is from OSRM B
This is live calculated and you may move the marker around as you like.
finddiffs
To brute force finding differences in routing use finddiffs
./finddiffs --minx 8.12 --maxx 8.57 --maxy 52.12 --miny 51.72
It will randomly generated routes and print a link to to stdout if the 2 routes differ by duration/distance.
For finding the bounding box of your data you may use osmium
osmium fileinfo -e -g data.bbox nrw.pbf
