transit_model

transit_model is a rust crate to manage transit data. Its model corresponds to the one used in navitia. This repository also provides :

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

Compile

cargo build --release

Compile for KV1

The KV1 format needs a additional dependency called Proj.4 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.4 version 6.1.0 installed on your system. See Proj.4 installation instructions or take a look at our Dockerfile.

[Proj.4](https://proj4.org/) is configured as a `feature` of the `transit_model`
crate.  Once [Proj.4](https://proj4.org/) is installed, 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!

### Using Proj.4
If you want to use [Proj.4](https://proj4.org/) 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")]`.

## Converting from GTFS to NTFS

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](src/documentation/gtfs2ntfs.md).

```json
{
    "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"
    }
}
