OpenTripPlanner

Note: this wiki is targeted primarily at the OTP development community. For general information about the project, please visit opentripplanner.org

OpenTripPlanner (OTP) is an open source multi-modal trip planner, which runs on Linux, Windows, or potentially any platform with a Java virtual machine. OTP is released under the LGPL license. As of Summer 2014, the code is under active development with a variety of deployments around the world, and we are working toward a 1.0 release in the coming year.

Latest Project Updates:

  • In 2014 OpenTripPlanner was a focal point in the Dutch Transport Ministry's MMRI (MultiModal Travel Information) project which encouraged investment in trip planning platforms and services. A consortium of five companies worked together on extending OpenTripPlanner to improve performance in large regional transport networks and account for real-time vehicle delay. Plannerstack is now working toward hosting OpenTripPlanner and Bliksem RRRR as services, including high quality open data integration for the Netherlands.

  • OpenTripPlanner has become Software Freedom Conservancy's thirty-first member project. Conservancy is a non-profit public charity that provides a range of financial and administrative services to member projects that develop Free, Libre, and Open Source Software (FLOSS). By joining Conservancy, OpenTripPlanner obtains the benefits of a formal non-profit organizational structure while keeping the project focused on software development and documentation. See SFC for more details.

  • Portland's TriMet relaunched its official trip planner, now powered by OTP, on August 6, 2012, following a successful 10-month beta run. Read more about the project, and see also TriMet's 2009-2011 OTP Final Report.

Status

OpenTripPlanner is presently at version 0.11.0. (see changelog)

The software currently:

  • Plans multi-modal walking, wheelchair, biking and transit trips
  • Takes travel time, road type/safety, and elevation data into account when planning bike trips, and provides an interface for customizing the weighting of these three factors
  • Shows graphical elevation profiles for bike trips
  • Imports data from GTFS, shapefiles, OpenStreetMap and the National Elevation Dataset
  • Plans trips in about 100ms in a moderate sized city
  • Exposes a RESTful API (XML and JSON), which other apps or front-ends can build on
  • Supports GTFS-Realtime for service changes and alerts
  • Supports Bike rental
  • Supports one-to-many and many-to-many searches for planning, alternatives analysis, and accessibility research purposes.

See the Milestones page for more information on what's next.

See PerformanceNYC for performance characteristics in a larger metropolitan area with extensive transit coverage.

Basic OTP Architecture

At the core of OpenTripPlanner is a library of Java code that finds efficient paths through multi-modal transportation networks built from OpenStreetMap and GTFS data. Several different services are built upon this library:

The OTP Routing API is a RESTful web service that responds to journey planning requests with initineraries in a JSON or XML representation. You can combine this API with OTP's standard Javascript front end to provide users with trip planning functionality in a familiar map interface, or write your own applications that talk directly to the API. This API is provided by a Java servlet which can be dropped into any servlet container. In simpler terms, the OTP REST API is provided by a plug-in for standards-compliant Java web servers.

The OTP Transit Index API is another RESTful web service that provides information derived from the input GTFS feed(s). Examples include routes serving a particular stop, upcoming vehicles at a particular stop, upcoming stops on a given trip, etc.

The term "OTP Analyst" refers to parts of OTP that apply the routing engine to transportation network analysis rather than end-to-end trip planning. OTP Analyst includes:

The OTP Analyst Web Services provide network analysis results such as travel time maps and isochrones as standard web Mercator tiles or GIS rasters via a WMS-derived API. These web services are conceptually separate from the routing API, but are provided by the same servlet: once you have a working OTP trip planner you can also use it to produce travel time maps and other visualizations of transit service. See this blog post for discussion and examples.

The OTP Analyst Batch Processor is a command-line tool that handles more complex one-off network analysis tasks. It uses the same core routing library and data sources as other OTP services, but allows for very open-ended configuration and the inclusion of population or opportunity data. While configuration and use are currently somewhat opaque for non-developers, the "Batch Analyst" is becoming a powerful tool for visualizing how transportation networks affect access to urban opportunities. See this article for an example case study on the effects of hurricane Sandy in New York.

Code Repository

To browse the source online visit https://github.com/openplans/OpenTripPlanner.

To create a local copy of the repository, use the following command:

$ git clone git://github.com/openplans/OpenTripPlanner.git

NOTE as part of a large project in the Netherlands we are currently restructuring the OpenTripPlanner project to reduce the number of Maven modules, clarify the naming scheme for those modules, and simplify installation and configuration for new users (see "stand-alone mode" below). The documentation in this wiki is therefore not in sync with the master branch of OTP (on which we carry out active development). All users and developers referencing this documentation will want to check out the stable git branch instead of the master branch, as it is quite recent but still follows the old naming scheme and structure.

Stakeholders and User Information

Background

The project began a collaborative effort among TriMet, OpenPlans, and the developers of FivePoints, OneBusAway and Graphserver, and has since grown to encompass a global community of users and developers. More information on OTP's origins is available at the Project History page.

In November of 2013, OpenTripPlanner became the thirty-first member project of the Software Freedom Conservancy.
