get_route_frequency: Calculate frequencies per route from tidytransit gtfs object...

In b-tomhave/gtfsFunctions: Package of Useful R Functions for Interacting With GTFS Data

Description

Calculate frequencies per route from tidytransit gtfs object (This is addapted from tidytransit frequencies.R). Uses stop_times and trips. If no service_ids provided, service with most trips used

Usage

get_route_frequency(
  gtfs_obj,
  by_directionId = T,
  by_headsign = T,
  by_TOD = T,
  tod_earlyStart = 14400,
  tod_AMPeakStart = 21600,
  tod_MiddayStart = 32400,
  tod_PMPeakStart = 54000,
  tod_EveningStart = 66600,
  tod_NightStart = 75600,
  tod_NightEnd = 86400,
  startHHMMSS = "06:00:00",
  endHHMMSS = "22:00:00",
  service_ids = NULL
)

Arguments

gtfs_obj	object from tidytransit read_gtfs()
by_directionId	(optional) TRUE/FALSE indicating if segmenting route frequencies by direction_id (default TRUE)
by_headsign	(optional) TRUE/FALSE indicating if segmenting frequencies trip_headsgign overall.
by_TOD	(optional) TRUE/FALSE indicating if segmenting frequencies by time of day periods or overall. If by_TOD == T don't provide start and end HHMMSS
tod_earlyStart	(optional) If by_TOD = False, specify an integer (seconds past midnight) for tod Early period start (default 14400 (4AM))
tod_AMPeakStart	(optional) If by_TOD = False, specify an integer (seconds past midnight) for tod AM Peak period start (default 21600 (6AM))
tod_MiddayStart	(optional) If by_TOD = False, specify an integer (seconds past midnight) for tod Midday period start (default 32400 (9AM))
tod_PMPeakStart	(optional) If by_TOD = False, specify an integer (seconds past midnight) for tod PM Peak period start (default 54000 (3PM))
tod_EveningStart	(optional) If by_TOD = False, specify an integer (seconds past midnight) for tod Evening period start (default 66600 (6:30PM))
tod_NightStart	(optional) If by_TOD = False, specify an integer (seconds past midnight) for tod Night period start (default 75600 (9PM))
tod_NightEnd	(optional) If by_TOD = False, specify an integer (seconds past midnight) for tod Night period end (default 86400 (4AM (i.e. 28:00)))
startHHMMSS	(optional) If by_TOD = False, specify a string HH:MM:SS (default 06:00:00 (6 am))
endHHMMSS	(optional) If by_TOD = False, specify a string HH:MM:SS (default 22:00:00 (10 pm))
service_ids	(optional) a string from the calendar dataframe identifying a particular service schedule. If none provided, service with most trips used

Value

tbl_df headways per route
