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.

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 7)

end_hour

(optional) an integer indicating the end hour (default 20)

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

a gtfs_obj with a dataframe of stops (gtfs_obj$.$stops_frequency) with a "Trips" variable representing the count trips taken through each stop for a route within a given time frame

Examples

data(gtfs_obj) gtfs_obj <- get_stop_frequency(gtfs_obj) x <- order(gtfs_obj$.$stops_frequency$headway) head(gtfs_obj$.$stops_frequency_df[x,])
#> NULL
