tidytransit (version 1.0.0)

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 = NULL,
  by_route = 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. If not provided the service_id with the most departures is used

by_route

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

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$mean_headway)
head(stop_frequency[x,])
# }
