Computing Isochrones with fastisochrones

openrouteservice
1

Hi! I am trying to compute isochrones for a project of mine and I am succeeding in computing isochrones for over an hour (2 hours with intervals of 30 minutes) with the local deployment through Docker. However these isochrones take a long time to compute and I have a long list of points for which I would like to have the isochrones.
I saw in the config files (example-ors-config.yml & example-ors-config.env) that there are some configuration values for fastisochrones under isochrones, but I am wondering how can I make use of these fast isochrones? I actually do not mind if the result is somewhat approximative since I only need a rough estimate but I need to be fast.
For information I am configuring the openrouteservice instance via the ors-config.env file and I am trying to get isochrones all over metropolitan France.

Any help would be appreciated! Thanks in advance.

Hi @felipe-notilus,

this is still undocumented :sweat: .
Check our test config for the correct position to configure this:

And translate from yml to env by hierarchy.

Also see ors.endpoints.isochrones | openrouteservice backend documentation

Best regards

Hi @amandus!

Thank you for your reply. I added these lines in the profile that I am using (car) but the behaviour does not seem to change. I deleted the graph folder so that it would be rebuilt from scratch. Is there anything else I should change in the usage, such as the endpoint name or maybe an extra parameter to be passed on when I perform the api call?

Thanks again!

Felipe.

Hi @felipe-notilus

did you also add entries for:
ors.endpoints.isochrones.fastisochrones ?
If you did, maybe provide your full config as well as the request you are trying

Best regards

I do have entries for ors.endpoints.isochrones.fastisochrones. Here are the uncommented lines from the ors-config.env file:

ors.endpoints.isochrones.enabled=true
ors.endpoints.isochrones.attribution=openrouteservice.org, OpenStreetMap contributors
ors.endpoints.isochrones.maximum_locations=2

ors.engine.profiles.car.preparation.methods.fastisochrones.weightings=recommended, shortest
ors.engine.profiles.car.preparation.methods.fastisochrones.maxcellnodes=5000

I also tried adding a line ors.endpoints.isochrones.fastisochrones.enabled=true to no avail. The .osm.pbf file is a custom one grouping about 4 departments of France. The ors-config.env file is located at the same level as the docker-compose.yml file, and I know it is taken into account because the behaviour changes if I change the time limit for example.

The request I am executing to get the isochrones is the following:

import requests

max_time = 7200

dampierre = [1.9882237263532425, 48.70487141802938]
heidelberg = [8.681495,49.41461]

body = {
    "locations":[dampierre],
    "range_type": "time",
    "range":[max_time],
    "interval": int(max_time/4)
    }

headers = {
    'Accept': 'application/json, application/geo+json, application/gpx+xml, img/png; charset=utf-8',
    'Content-Type': 'application/json; charset=utf-8'
}
call = requests.post('http://localhost:8080/ors/v2/isochrones/driving-car', json=body, headers=headers)

Hey,

would you mind sharing your docker-compose.yml?

Best regards

Hi Jakob, sure here it is:

    # The healthcheck allows you to monitor the status of the ORS application.

    #  timeout: 2s
    #  retries: 3
    #  disable: false

# ----------------- Docker Volumes configuration ------------------- #
# Define the Docker managed volumes for the ORS application. For more info on Docker Volumes see https://docs.docker.com/compose/compose-file/07-volumes/
# Volumes are used to persist the data and configuration of the ORS application.
# If you want to use volumes, uncomment the following lines and remove the ./ prefix from the volume paths in 'services.ors-app.volumes'.
#volumes:
#    graphs:
#    elevation_cache:
#    config:
#    logs:
#    files:

I have also ran ORS on a VM and in that case the only thing I have changed is the allocated ram to java to follow the rule of thumb. Other than that the only change has been to uncomment the line env_file: ors-config.env.

Thank you :slight_smile:

Hey,

thanks a lot :slight_smile:

You are setting

ors.endpoints.isochrones.maximum_range_time.0.profiles=driving-car, driving-hgv
ors.endpoints.isochrones.maximum_range_time.0.value=8000

but also

ors.endpoints.isochrones.fastisochrones.maximum_range_time.0.profiles=driving-car, driving-hgv
ors.endpoints.isochrones.fastisochrones.maximum_range_time.0.value=10800

Thus, it might be the case that up to a time of 8000, openrouteservice is still calculating regular isochrones, which will take some time.

Apart from that, what do you mean by “take a long time to compute” for a 2 hour isochrone?

Could you enable DEBUG-output via

logging.level.org.heigit=DEBUG

and show the output of docker compose logs -f for your container?
When requesting isochrones, you should see lines similar to

ors-app  | 2024-08-22 15:09:38 DEBUG        http-nio-8082-exec-4 [ o.h.o.i.b.f.FastIsochroneMapBuilder      ]   Build shell concave hull 0.02184736

showing that fastisochrones are being calculated.

Hi Jakob,

Indeed when I see the logs with the debug level I see what you mention (I will paste the logs at the en of the message). I had suspected something like that and I had tried to trigger the fastisochrones this way but it was before I added the config lines under the car profile as suggested by amandus. By the way the Map builder is FastIsochrone even if the max time is within the limit set to “isochrones”.

I went back to my previous config (without the lines proposed by amandus), rebuilt the graph folder and I performed the request again. It then uses ConcaveBallsIsochroneMapBuilder as expected. So now I know how to trigger the FastIsochroneMapBuilder, thank you! However, what now puzzles me is that for exactly the same point and max_time, FastIsochrone takes longer - hence the reason I thought it was still not working after the suggestion by amandus. In my machine the 2 hours isochrone with half hour intervals took a bit over 40 seconds with FastIsochrone and about 33 seconds with the regular MapBuilder.

By “a long time” I mean that it would be unfeasible to do it for the total amount of points I have, some 20k, within a reasonable time and the budget at disposal :sweat_smile:. Also given that when I use the full France osm.pbf file the computation takes longer (can’t compare apples to apples since the French map is too big to instantiate ORS in my machine but in the VM a single point takes about 2.5/3 minutes).

Also, I am not really interested in super precise isochrones. Is there any config setup that could help speed things up, sacrificing the precision of the isochrone?

As promised here are the logs with debug level. For the FastIsochroneMapBuilder:

Hey,

great to see that apparently fastisochrones are being used!
Sad, however, that they don’t seem to be that fast after all :smiley:

We have a blog post that explains the idea behind fastisochrones.

They were developed to make large-scale isochrones possible at all - where large-scale means something beyond 6 hours, so basically country-size isochrones.
Thus, it might be that algorithmically, 2 hours are at the threshhold where classic isochrones become too large to be calculated fast, but fast-isochrones have too much of an overhead to provide a lot of value.

However, there is one configurable value, namely maxcellnodes, determining the partition size (i.e. the number of nodes in one partition).
You can definitely try playing around with it to see if that speeds up things.

If not, there might be something wrong with the implementation…

Best regards

Hi Jakob,

Thanks for the information!
Actually, I think I found a way to make it faster but I am not sure if it is something that is actually intended to happen. When using the regular map builder, setting a “smoothing” parameter in the request does not make it faster, it only smoothes out the returned polygone. However, when using FastIsochrone map builder it actually returns the response much faster. The elapsed time per point came down from 40s to about 8s with a smoothing factor of 45 in my computer. On the VM where I have the ORS instance for all of France it came down from over 3 minutes to a bit less than 30s. So now if I parallelize the computation across CPUs, I can easily reach about 7s per point!

Thanks again for all your help!
