transit_model is a Rust crate managing transit data by implementing the NTFS model v0.9.1 (used in navitia). See the section NTFS: Level of Support for more details about the level of support of the NTFS standard.

This repository also provides :

• (incomplete) GTFS to NTFS and (soon) NTFS to GTFS conversion.
• (incomplete) Generation of transfers. .
• Merge [NTFS] (https://github.com/CanalTP/ntfs-specification/blob/master/ntfs_fr.md).

cargo build --release

The KV1 format needs a additional dependency called PROJ which allows the transformation of localization coordinates. crates.io provides a proj crate which is a binding to the C library (version 6.1.0). This means you need PROJ version 6.1.0 installed on your system. See PROJ installation instructions.

PROJ is configured as a feature of the transit_model crate. Once PROJ is installed on your machine, you need a few more dependencies for building transit_model.

apt install -y clang libssl-dev
cargo build --features=proj

Now, you should be able to use the converter kv12ntfs. Enjoy!

If you want to use PROJ in your code, you can if you activate the proj feature (cargo build --features=proj). Then don't forget to protect your code with #[cfg(feature="proj")].

NTFS needs a Dataset and a Contributor. Default ones are provided by the command but you can pass a json file that contains some information for creating a Dataset and a Contributor as explained in the documentation.

{
    "contributor": {
        "contributor_id" : "your_contributor_id",
        "contributor_name" : "your_contributor_name",
        "contributor_license" : "your_contributor_license",
        "contributor_website" : "your_contributor_website"
    },
    "dataset": {
        "dataset_id" : "your_dataset_id",
        "dataset_desc" : "optional_dataset_desc",
        "dataset_system" : "optional_dataset_system"
    }
}

cargo test

transit_model is partially supporting v0.9.1 of NTFS (see CHANGELOG in French). From the standard, some of the functionalities are not fully supported:

• Management of pathways introduced in version v0.8 is not supported
• No support for all periodic description (files grid_calendars.txt, grid_exception_dates.txt, grid_periods.txt and grid_rel_calendar_line.txt)
• No support for Line Groups (files line_groups.txt and line_group_links.txt)
