Note that this branch contains OpenTripPlanner 2, the second major version of OTP, which has been under development since Q2 2018. The latest version of OTP is v2.2.0, released in November 2022.
If you do not want to test or explore this version, please switch to the final 1.x release
v1.5.0 or the
dev-1.x branch for any patches and bugfixes applied to the v1.5.0 release.
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.
The main Java server code is in
Leaflet mapping library in
src/client/. This client is now primarily used for testing, with most
major deployments building custom clients from reusable components. The Maven build produces a
unified ("shaded") JAR file at
target/otp-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.
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.
The OpenTripPlanner project was launched by Portland, Oregon's transport agency TriMet (http://trimet.org/) in July of 2009. As of this writing in Q3 2020, it has been in development for over ten years. See the main documentation for an overview of OTP history and a list of cities and regions using OTP around the world.
