transit_model is a Rust crate to manage, convert and enrich transit data.
This is done by implementing the NTFS model (used in navitia).

This repository regroups crates that offer enabler-libraries and binaries to convert and enrich transit data.

Additionally, transit_model is itself a library providing various functionalities. Please refer to the code, examples and documentation to discover them.

Please check documentation attached to each crate:

Usage with Docker

For all the binaries mentioned above, it is also possible to use them with Docker. All the binaries are part of the image navitia/transit_model which is tagged alongside the crate transit_model. Let's use gtfs2ntfs as an example.

mkdir output-ntfs/
docker run \
	--volume "${PWD}/tests/fixtures/gtfs:/gtfs" \
	--volume "${PWD}/output-ntfs:/ntfs" \
	navitia/transit_model \
	gtfs2ntfs \
	--input /gtfs \
	--output /ntfs

Setup Rust environment

transit_model is developed in Rust.

If you want to contribute or install binaries, you need to install a Rust environment: see rustup.rs

PROJ dependency

Based on PROJ, the proj crate allows the transformation of localization coordinates.

Some transit_model's crates (see each documentation) use PROJ.
So it must be installed on the system to compile and use those crates.

PROJ for binaries

The proj crate requires PROJ.

If your system has pkg-config and a sufficiently new version of PROJ installed, it will be used. Otherwise, the crate falls back to building PROJ from source, which requires some build time dependencies.

To install PROJ build time dependencies, you can execute the following command (On Debian systems):

make install_proj_deps

You can also install the required PROJ version system-wide to avoid full rebuild (ex: cargo clean):

make install_proj

PROJ installation instructions may help, too.

Using PROJ and transit_model as a developer

proj crate is a binding to the C library.

PROJ is configured as a feature of the transit_model crate.
So to use it for coding, the proj feature must be activated (cargo build --features=proj).
Then specific code should be conditionally enabled with #[cfg(feature="proj")].

NTFS Level of Support

transit_model is supporting most of NTFS format.
From the standard, some of the functionalities are not fully supported:

  • No support for Line Groups (files line_groups.txt and line_group_links.txt).
  • The field trip_short_name_at_stop in stop_times.txt introduced in version v0.10.0 (see NTFS changelog in French) is not supported.
