get_trip_duration: Get trip duration

Description

Returns the duration of each specified trip_id.

Usage

get_trip_duration(gtfs, trip_id = NULL, unit = "min")

Value

A data.table containing the duration of each specified trip.

Arguments

gtfs

A GTFS object, as created by read_gtfs().

trip_id

A string vector including the trip_ids to have their duration calculated. If NULL (the default) the function calculates the duration of every trip_id in the GTFS.

unit

A string representing the time unit in which the duration is desired. One of "s" (seconds), "min" (minutes, the default), "h" (hours) or "d" (days).

Details

The duration of a trip is defined as the time difference between its last arrival time and its first departure time, as specified in the stop_times table.

Examples

# \dontshow{
  old_dt_threads <- data.table::setDTthreads(1)
  on.exit(data.table::setDTthreads(old_dt_threads), add = TRUE)
# }
data_path <- system.file("extdata/spo_gtfs.zip", package = "gtfstools")

gtfs <- read_gtfs(data_path)

trip_duration <- get_trip_duration(gtfs)
head(trip_duration)

trip_ids <- c("CPTM L07-0", "2002-10-0")
trip_duration <- get_trip_duration(gtfs, trip_id = trip_ids)
trip_duration

trip_duration <- get_trip_duration(gtfs, trip_id = trip_ids, unit = "h")
