In trread: Read, Validate, and Analyze Files in the General Transit Feed Specification

Description

Get Stop Frequency

Usage

get_stop_frequency(gtfs_obj, start_hour = 6, end_hour = 22,
  service_id = "", 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_id	(optional) a string from the calendar_df dataframe identifying a particular service schedule.
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 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$stops_frequency_df$headway)
head(gtfs_obj$stops_frequency_df[x,])
