Design innovative solutions thanks to Navitia.io, a robust, easy-to-integrate RESTful API based on the largest open database.

#### Overview
Navitia (pronounce [navi-sia]) is the open API for building cool stuff with mobility data. Navitia.io is an open-source, open-service API suite based on open data, offering advanced features dedicated to mobility such as multimodal and intermodal route searches, traffic information, timetable display, powerful autocompletion and the isochrone feature.

It provides the following services:

- multi-modal journeys computation.
- line schedules.
- next departures.
- exploration of public transport data.
- search & autocomplete on places.
- and sexy things such as isochrones.

Have a look at these [examples](https://doc.navitia.io/#some-examples) to learn what services we provide and how to use them.

#### Approach
Navitia is an open-source web API, initially built to provide traveler information on urban transportation networks.
Its main purpose is to provide day-to-day informations to travelers.
Over time, Navitia has been able to do way more, sometimes for technical and debuging purpose or because other functional needs fit quite well in what Navitia can do or just because it was quite easy and super cool.

Technically, Navitia is a HATEOAS API that returns JSON formated results.
