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.
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.
