OpenTripPlanner (OTP) is an open source multi-modal trip planner. It depends on open data in open standard file formats (GTFS and OpenStreetMap), and includes a REST API for journey planning as well as several map-based Javascript clients. OpenTripPlanner can also create travel time contour visualizations and compute accessibility indicators for planning and research applications. For more information, see the project website: http://opentripplanner.org
Installation instructions are available on the website: http://opentripplanner.org/wiki/
OpenTripPlanner is a multi-module Maven project. It contains the following sub-modules:
otp-core/- Core routing algorithms, data structures, libraries, and stand-alone server.otp-analyst-client/- A Javascript client focusing on OTP analyst web service visualizations.otp-geocoder/- A servlet that converts addresses to geographic locations using web services.otp-leaflet-client/- The newer Javascript client providing a map-based UI for trip planning.otp-municoder/- A servlet that determines which administrative area a coordinate falls within.otp-openlayers-client/- The original Javascript client providing a map-based UI for trip planning.otp-rest-servlet/- A servlet that provides the OTP REST API within a servlet container.otp-thrift-api/- A Thrift API supporting lower-level queries than the REST API.otp-admin-client/- A client for administration.
OTP also includes the following subprojects which must be built separately:
otp-datastore/- A Play-based backend for logging OTP queries.otp-gvsig/- An OpenTripPlanner-based extension to GVSIG.
OpenTripPlanner is a collaborative project incorporating code, translation, and documentation from contributors around the world. We welcome new contributions and prefer to format our code according to GeoTools-based formatting guidelines; an Eclipse autoformatter can be found at the root of this project (https://raw.github.com/openplans/OpenTripPlanner/master/formatter.xml). Further development guidelines can be found on the project wiki (https://github.com/openplans/OpenTripPlanner/wiki/DevelopersGuide).
The OpenTripPlanner project was launched by Portland, Oregon's transport agency TriMet (http://trimet.org/), and began in July of 2009 with a kick-off conference bringing together transit agencies and the authors of the major open source transit passenger information software of the day: David Emory of FivePoints, Brian Ferris of OneBusAway, and Brandon Martin-Anderson of GraphServer. From 2008 through 2012, development was coordinated by New York nonprofit OpenPlans (http://openplans.org/). By early 2013, OpenTripPlanner had become the primary trip planning software used by TriMet in the Portland regional trip planner (http://ride.trimet.org/) and was backing several popular mobile applications. Public-facing OpenTripPlanner instances were available in ten countries throughout the world. At this point the OpenPlans transportation software team became the independent consultancy Conveyal (http://www.conveyal.com/). The original OpenTripPlanner development team from OpenPlans still actively participates in programming, design, and community coordination via the mailing list and their roles on the OTP Project Leadership Committee.
As of Summer 2013, the OpenTripPlanner project has been accepted for membership in the Software Freedom Conservancy (SFC). SFC handles the legal and financial details common to many open source projects, providing a formal framework for OTP and allowing contributors to concentrate on the code. For more information, see the SFC website at http://sfconservancy.org/.
The main forums through which the OpenTripPlanner community organizes development and provides mutual assistance are our two Google discussion groups. Changes and extensions to OTP are debated on the developers' list (opentripplanner-dev). More general questions and announcements of interest to non-developer OTP users should be directed to the opentripplanner-users list.
