r5r is an R package for rapid realistic routing on multimodal transport networks (walk, bike, public transport and car). It provides a simple and friendly interface to R5, the Rapid Realistic Routing on Real-world and Reimagined networks.

r5r is a simple way to run R5 locally, what allows users to generate detailed routing analysis or calculate travel time matrices using seamless parallel computing. See a detailed demonstration of r5r in this intro Vignette. Over time, r5r migth be expanded to incorporate other functionalities from R5

This repository contains the R code (r-package folder) and the Java code (java-api folder) that provides the interface to R5. Soon, this could also become a python library.


To use r5r, you need to have Java SE Development Kit 11 installed on your computer. No worries, you don’t have to pay for it. The jdk 11 is freely available from the options below:

# From CRAN

# or use the development version with latest features
  devtools::install_github("ipeaGIT/r5r", subdir = "r-package")


The package has four fundamental functions.

  1. setup_r5
    • Downloads and stores locally an R5 Jar file (Jar file is downloaded only once)
    • Builds a multimodal transport network given a street network in .pbf format (mandatory) and one or more public transport networks in GTFS.zip format (optional).
  2. detailed_itineraries
    • Returns a data.frame sf LINESTRINGs with one or multiple alternative routes between one or multiple origin destination pairs. The data output brings detailed information on transport mode, travel time, walk distance etc for each trip section
  3. travel_time_matrix
    • Fast function that returns a simple ‘data.frame’ with travel time estimates between one or multiple origin destination pairs.
  4. accessibility
    • Fast computation of access to opportunities. The function returns a data.table with accessibility estimates for all origin points by transport mode given a selected decay function. Multiple decay functions are available, including step (cumulative opportunities), logistic, fixed Exponential and linear.

Demonstration on sample data

See a detailed demonstration of r5r in this intro Vignette. To illustrate functionality, the package includes a small sample data set of the public transport and Open Street Map networks of Porto Alegre (Brazil). Three steps are required to use r5r, as follows.

# allocate RAM memory to Java
options(java.parameters = "-Xmx2G")

# 1) build transport network, pointing to the path where OSM and GTFS data are stored
path <- system.file("extdata/poa", package = "r5r")
r5r_core <- setup_r5(data_path = path, verbose = FALSE)

# 2) load origin/destination points and set arguments
points <- read.csv(system.file("extdata/poa/poa_hexgrid.csv", package = "r5r"))
mode <- c("WALK", "BUS")
max_walk_dist <- 3000   # meters
max_trip_duration <- 60 # minutes
departure_datetime <- as.POSIXct("13-05-2019 14:00:00",
                                 format = "%d-%m-%Y %H:%M:%S")

# 3.1) calculate a travel time matrix
ttm <- travel_time_matrix(r5r_core = r5r_core,
                          origins = points,
                          destinations = points,
                          mode = mode,
                          departure_datetime = departure_datetime,
                          max_walk_dist = max_walk_dist,
                          max_trip_duration = max_trip_duration)

# 3.2) or get detailed info on multiple alternative routes
det <- detailed_itineraries(r5r_core = r5r_core,
                            origins = points[370, ],
                            destinations = points[200, ],
                            mode = mode,
                            departure_datetime = departure_datetime,
                            max_walk_dist = max_walk_dist,
                            max_trip_duration = max_trip_duration,
                            shortest_path = FALSE)

# 4) Calculate number of schools accessible within 20 minutes 
access <- accessibility(r5r_core = r5r_core,
                        origins = points,
                        destinations = points,
                        opportunities_colname = "schools",
                        decay_function = "step",
                        cutoffs = 21,
                        mode =  c("WALK", "TRANSIT"),
                        verbose = FALSE)
