OpenTripPlanner for R

R build status codecov Project Status: Active – The project has reached a stable, usable state and is being actively developed. DOI status CRAN_Status_Badge

opentripplanner is an R package that provides a simple yet flexible interface to OpenTripPlanner (OTP). OTP is a multimodal trip planning service written in Java. For more information on what OTP is, see the prerequisites vignette.

opentripplanner can be used to interface with a remote instance of OTP (e.g. a website) or help you set up and manage a local version of OTP for private use. Basic setup and routing functions are outlined in the getting started vignette, while advanced functionality such as batch routing, isochrones, and customised setup is described in the advanced features vignette.

What’s New

The newest version of the package 0.5.0 (Jan 2023) focuses on increased routing speeds (3-4x faster) and expanding support for OTP v2.2. The new version also drops legacy support for R 3.6, and so now requires R 4.0 or later. See news for more details.

Installation

To use OpenTripPlanner on your local computer you will need to install Java 8 and download the latest version of OTP. Instructions on installing Java and setting up OTP can be found in the prerequisites vignette.
