https://topo.transport.data.gouv.fr/ a semantic database of transit objects (stops, lines, networks…).

This program is a toolkit to populate that database from a GTFS file.

It allows to populate missing features in the database.

The tool is designed to be idempotent: importing twice the same file, or different files from the same producer won’t generate any duplicate.

Transit topo tools are written in Rust.

You need an up to date rust tool-chain (commonly installed with rustup).

You need to configure config.toml in order to set which are the ids of basic identifiers (“bus”…) or property (“gtfs_id”).

See config.example.toml how to set it up.

Identifiers of entities can be the same across different producers. That is why we require to set a producer with the --producer (or -p) flag.

For instance, to import all the lines of the producer Q4 from the local file gtfs.zip, run:

cargo run --release -- -p Q4 -i gtfs.zip
