Parameter output_dir not working with detailed_itineraries(all_to_all = T) · Issue #327 · ipeaGIT/r5r · GitHub

When users set an output_dir, the function writes one .csv file with the results for each origin. However, it is common for users to repeat the same origin multiple times in the input of detailed_itineraries(). We also provide the all_to_all = T option so that users can easily run all-to-all analysis.

In these situations, the problem is that r5r writes one file for each origin but the file only contains the results for the 1st destination.

The .csv file should include the results from the origin to all destinations.

library(r5r)

# build transport network
data_path <- system.file("extdata/poa", package = "r5r")
r5r_core <- setup_r5(data_path)

# load origin/destination points
points <- read.csv(file.path(data_path, "poa_points_of_interest.csv"))

# inputs
departure_datetime <- as.POSIXct(
 "13-05-2019 14:00:00",
 format = "%d-%m-%Y %H:%M:%S"
)

det <- detailed_itineraries(
 r5r_core,
 origins = points,
 destinations = points,
 mode = c("WALK", "TRANSIT"),
 departure_datetime = departure_datetime,
 max_trip_duration = 30, 
 drop_geometry = T, 
 all_to_all = T, 
 shortest_path = F,
 suboptimal_minutes = 10,
 output_dir = './test'
)


ttm <- travel_time_matrix(
  r5r_core,
  origins = points,
  destinations = points,
  mode = c("WALK", "TRANSIT"),
  departure_datetime = departure_datetime,
  max_trip_duration = 30,
  output_dir = './test'

)
