(pronounce [navi-sia])

Welcome to the Navitia repository. Navitia is a service providing:

1. multi-modal journeys computation
2. line schedules
3. next departures
4. explore public transport data
5. sexy things such as isochrones

The API can be found at http://api.navitia.io/

For more information see

• documentation http://doc.navitia.io
• main web site http://www.navitia.io
• playground http://canaltp.github.io/navitia-playground/
• twitter @navitia https://twitter.com/navitia
• google groups navitia https://groups.google.com/d/forum/navitia
• channel #navitia on irc.freenode.net

The easiest way to do this is a to go to navitia.io. Signup, grab a token, read the doc and start using the API!

For a more friendly interface you can use the API through navitia playground (no matter the server used)

The easiest way to have your own navitia is to use the navitia docker-compose.

If you don't want to use the prebuilt docker images you can use the fabric scripts we use to deploy to api.navitia.io.

WARNING: Those scripts should be usable, but they are not meant to be completly generics and are designed for our own servers architecture.

Use this only if the docker does not suit your needs and if you are an experienced user 😉

if you want to build navitia, please refer to the installation documentation

You can also check the automated build script which is meant as a step by step tutorial for compiling and using navitia with ubuntu 16.04

At the root of the repository, several directories can be found:

1. source: contains the navitia source code (c++ and python)
2. third_party: third party developped modules
3. documentation: all the navitia documentation
4. (debug|release): by convention, the build repositories

Navitia is made of 3 main modules:

1. Kraken is the c++ core
2. Jörmungandr is the python frontend
3. Ed is the postgres database

Kraken and Jörmungandr communicate with each other through protocol buffer messages send by ZMQ.

Transportation data (in the GTFS format) or routing data (from OpenStreetMap for the moment) can be given to Ed. Ed produces a binary file used by Kraken.

More information here: https://github.com/CanalTP/navitia/wiki/Architecture

1. Gcc (or clang) as the C++ compiler (g++)
2. Cmake for the build system
3. Python for the api

Fork the github repo, create a new branch from dev, and submit your pull request!

Make sure to run the tests before submiting the pull request (make test in the build directory, you may also run make docker_test for important contributions)
