This is the Navitia repository.
Navitia is a service providing:
- multi-modal journeys computation
- line schedules
- next departures
- explore public transport data
- sexy things such as isochrones
The API can be found at http://api.navitia.io/
For more information see http://www.navitia.io/ or twitter @navitia or google groups navitia
At the root of the repository, several directories can be found:
- source: contains the navitia source code (c++ and python)
- third_party: third party developped modules
- documentation: all the navitia documentation
- (debug|release): by convention, the build repositories
Navitia is made of 3 main modules:
- Kraken is the c++ core
- Jörmungandr is the python frontend
- 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.
- Gcc as the C++ compiler (g++)
- Cmake for the build system
- Python for the api
- Doxygen and swagger for the automated documentation
For the installation procedure, please refer to the installation documentation
You can also refer to the automated build script to have a step by step setup guide for ubuntu 14.04

- OpenTripPlanner : the best known, written in java
- rrrr : the lightest one, written in python/c
- Synthese : a full stack, with CMS, written all in c++
- Mumoro : a R&D MUltiModal MUltiObjective ROuting algorithm
