Navitia.io is an API that helps people access and use public transportation data. It provides services for performing journey computations, getting line schedules, finding next departures, and discovering isochrones. Isochrones are locations that can be reached in the same amount of time from a person's starting point. This part of the API could, for example, be used to discover which stations could be reached within the next 60 minutes.
The street network used by navitia.io is extracted from OpenStreetMap, and all of the public transport data comes from networks that provide their timetables as open data.
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
