Overview

OpenTripPlanner (OTP) is an open source multi-modal trip planner, focusing on travel by scheduled
public transportation in combination with bicycling, walking, and mobility services including bike
share and ride hailing. Its server component runs on any platform with a Java virtual machine (
including Linux, Mac, and Windows). It exposes GraphQL APIs that can be accessed by various clients
including open source Javascript components and native mobile applications. It builds its
representation of the transportation network from open data in open standard file formats (primarily
GTFS and OpenStreetMap). It applies real-time updates and alerts with immediate visibility to
clients, finding itineraries that account for disruptions and service changes.

Note that this branch contains OpenTripPlanner 2, the second major version of OTP, which has
been under development since 2018 and is now the dominant one and the only one being supported.

Development

OpenTripPlanner is a collaborative project incorporating code, translation, and documentation from
contributors around the world. We welcome new contributions. Further
development guidelines can be found
in the documentation.

Contributing Guidelines

See CONTRIBUTING.md

Development History

The OpenTripPlanner project was launched by Portland, Oregon's transport agency TriMet
(http://trimet.org/) in July of 2009. As of this writing in September 2025, it has been in
development for over 16 years. See the main documentation for an overview of
OTP history and a list of
cities and regions using OTP around the
world.

Measuring OTP Performance

📊 Dashboard

We run a speed test (included in the code) to measure the performance for every PR merged into OTP.

More information about how to set up and run it.

Repository Layout

The main Java server code is in application/src/main/. OTP also includes a Javascript client based
on the MapLibre mapping library in client/src/. This client is now used for testing, with most
major deployments building custom clients from reusable components. The Maven build produces a
unified ("shaded") JAR file at otp-shaded/target/otp-shaded-VERSION.jar containing all necessary
code and dependencies to run OpenTripPlanner.

Additional information and instructions are available in the
main documentation, including a
quick introduction.

Getting in Touch

The fastest way to get help is to use our
Gitter chat room where most of the core
developers are. Bug reports may be filed via the Github
issue tracker. The OpenTripPlanner
mailing list is used almost exclusively for
project announcements. The mailing list and issue tracker are not intended for support questions or
discussions. Please use the chat for this purpose. Other details of
project governance can be found in the
main documentation.
