Hi,
I am working with travel times for Prague (CZ) and I It looks like the max_walk_time is overwriting max_trip_duration when mode is only WALK.
The package documentation says max_walk_time should only be applied when mode is TRANSIT.
max_walk_time An integer. The maximum walking time (in minutes) to access and egress the transit network, or to make transfers within the network (...).library(r5r)
# build transport network
r5r_core <- setup_r5("USING ONLY OSM FROM GEOFRABIK")
# load origin/destination points
origins<- "SEE FILE ATTACHED"
destinations <- "SEE FILE ATTACHED"
# IF max_walk_time = 15 the result has 5,985 lines
# IF max_walk_time = max_trip_duration = 120L the result has 474,288 lines
ttm <- travel_time_matrix(
mode = "WALK",
output_dir = NULL,
r5r_core = r5r_core,
origins = origins,
destinations = destinations,
hour_departure = "07:30:00",
time_window = 10L, # time window (minutes)
percentiles = 50L, # get median travel times
mode_egress = "WALK",
fare_structure = NULL, # if we want to include travel cost
max_fare = Inf, # max value that trips can cost
max_walk_time = 15, # 1km # max time (minutes) to access and egress the transit network
max_bike_time = Inf, # max time (minutes) to access and egress the transit network
max_car_time = Inf, # max time (minutes) to access and egress the transit network
max_trip_duration = 120L, # max trip duration (minutes) - 2 hours
walk_speed = 4, # Average walk speed in km/h
bike_speed = 16, # Average bike speed in km/h
max_rides = 3, # max number of public transport rides allowed in the same trip
max_lts = 2, # maximum level of traffic stress that cyclists will tolerate
draws_per_minute = 5L,
n_threads = Inf,
verbose = FALSE,
progress = FALSE)
