In ppintosilva/anprflows: Explore and Model ANPR Traffic Flows

Description

Get the subset of flows whose OD pairs account for the top p proportion of total or period-wise observed traffic flow. Returns all od pairs up to the first od pair that exceeds p.

Usage

cut_flows(
  flows_od,
  flows_l,
  time_resolution,
  locations = NULL,
  pairs = NULL,
  filter_dayperiod = "morning",
  fill_gaps = TRUE,
  filter_weekdays = c(1:5),
  min_t = NULL,
  max_t = NULL
)

Arguments

flows_od	flows at ods [tibble][tibble::tibble-package]
flows_l	flows at locations [tibble][tibble::tibble-package]
time_resolution	temporal resolution of flow tibbles
locations	filter observations occurring at these locations (vector)
pairs	filter observations involving these od pairs [tibble][tibble::tibble-package]
filter_dayperiod	filter observations occurring at this period of the day
fill_gaps	whether to make missing time steps explicit
filter_weekdays	filter observations occurring on these weekdays
min_t	first expected time step, defaults to minimum time in data
max_t	last expected time step, defaults to maximum time in data

Value

list with updated tibbles of flows_od and flows_l
