Gathering additional data

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

Tip

If you used the automatic data download tool on a config file where matsim.output appears under the run section or where mode_choice is set to true, OpenStreetMap data should have already been downloaded regardless of which area in France you are building the synthetic population on. As for the GTFS, some datasets are downloaded automatically only for Île-de-France and Nouvelle Aquitaine.

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:

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
