Add --sei (same start-end-identical) 
Try to filter out diffs where the route never reaches the same
destination. This can happen when the random location is far of
the road network and the snap-on road is not in the graph anymore
due to profile changes. This may also happen on the edges of
your area/pbf file.

README.md

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
