OpenTripPlanner (OTP) is an open source multi-modal trip planner which runs on Linux, Mac, Windows, or potentially any platform with a Java virtual machine. Documentation on the usage and configuration of current versions of OTP has been moved to readthedocs. This documentation is automatically built and published from version-controlled Markdown source within the project's github repository.
Legacy documentation is still present in this wiki for any developers using older versions of OTP who may wish to consult it.
