tidytransit (version 0.7.1)

get_stop_frequency: Get Stop Frequency

Description

Note that some GTFS feeds contain a frequency data frame already. Consider using this instead, as it will be more accurate than what tidytransit calculates.

Usage

get_stop_frequency(
  gtfs_obj,
  start_hour = 6,
  end_hour = 22,
  service_ids = c(),
  dow = c(1, 1, 1, 1, 1, 0, 0),
  by_route = TRUE,
  wide = FALSE
)

Arguments

gtfs_obj

a list of gtfs dataframes as read by read_gtfs().

start_hour

(optional) an integer indicating the start hour (default 6)

end_hour

(optional) an integer indicating the end hour (default 22)

service_ids

(optional) a set of service_ids from the calendar dataframe identifying a particular service id

dow

(optional) integer vector indicating which days of week to calculate for. default is weekday, e.g. c(1,1,1,1,1,0,0)

by_route

default TRUE, if FALSE then calculate headway for any line coming through the stop in the same direction on the same schedule.

wide

(optional) if true, then return a wide rather than tidy data frame

Value

dataframe of stops with the number of departures and the headway (departures divided by timespan) as columns.

Examples

# NOT RUN {
data(gtfs_duke)
stop_frequency <- get_stop_frequency(gtfs_duke)
x <- order(stop_frequency$headway)
head(stop_frequency[x,])
# }
