Gathering additional data

In this section we refere to the same data directory structure as described when gathering the data for the synthetic population.

I) Road network (OpenStreetMap)

The road network in the pipeline is based on OpenStreetMap data. A cut-out for Île-de-France is available from Geofabrik:

• Île-de-France OSM

• We recommend to use the fixed snapshot from 01/01/2022: ile-de-france-220101.osm.pbf

• Download ile-de-france-220101.osm.pbf and put it into the folder data/osm_idf.

II) Public transit schedule (GTFS)

A digital public transport schedule for Île-de-France is available from Île-de-France mobilités. Since 2023 you are required to create an account and accept the data license before making use of the data.

• Go to Île-de-France GTFS

• Create an account “Connexion” on top of the page

• Once you have created a valid account, go back to the page and click “Exporter la donnée”

• In the popup window, accept the use conditions and select “CSV” type, then click “Télécharger” to download

• The resulting file is not the data itself, but only contains a link to them. Open the downloaded CSV and find the URL starting with https://data.iledefrance-mobilites.fr/api/v2/catalog/datasets/...

• Enter the URL in your browser and download the file IDFM-gtfs.zip

• Put IDFM-gtfs.zip into the folder data/gtfs_idf

Note that this schedule is updated regularly and is only valid for the next three weeks.

Overview

In your directory structure, there should now be the following additional files:

• data/osm_idf/ile-de-france-latest.osm.pbf

• data/gtfs_idf/IDFM-gtfs.zip
