Software for Creating APIs

Software that you can set up to provide an API to transit and multimodal data.

• GraphHopper Routing Engine Open source routing engine for OpenStreetMap. Use it as Java library or server.
• gtfs-server - A web server, written in Rust that uses PostGIS as a backend to serve GTFS data via a HTTP endpoint
• hafas-rest-api – Expose a HAFAS endpoint as a REST API.
• Linked Connections - An open-source, scalable intermodal route planning engine, which allows clients to execute the route planning algorithm (as opposed to the server). Uses GTFS data.
• MOTIS - Multi Objective Travel Information System, written in C++ and Java. Can consume schedule timetables in the GTFS or HAFAS format as well as real time information in the GTFS-RT (and RISML, a propriatary format at Deutsche Bahn) as input data. For pedestrian routing (handled by Per Pedes Routing) and car routing (handled by OSRM) OpenStreetMap data is used.
• Navitia is the opensource engine behind the Navitia.io live API.
• OneBusAway - A Java app that consumes GTFS and GTFS-Realtime (along with other formats) and turns them into an easy to use REST API.
• OpenTripPlanner - An open source platform for multi-modal and multi-agency journey planning, as well as returning information about a multi-modal graph (using data sources such as GTFS and OpenStreetMap).
• pyBikes - Software powering CityBikes for worldwide bikeshare system info
• TransitClock - Java application that can consume raw vehicle positions and generate prediction times in formats such as GTFS-realtime. Formerly known as "Transitime".
• TransiCast - Provides public transportation data for North America in a single, integrated call and response format. The data is provided in stream-parsable XML and JSON formats. Open-source on Google Code. Hosted version at www.transitcast.com requires payment.
