drt_drtm: Demand responsive transport model class.

In munterfinger/drtplanr: Experimental demand-responsive transport planner

Description

Creates a demand responsive transport representation of in an Area of Interest (AOI). The constructor takes a polygon (aoi), point population values (pop) and the number of virtual stations to plan as input. Then it retrieves the street network in the area of interest from OSM. Based on the OSM data a routing graph for walking and driving is created.

Usage

drt_drtm(
  model_name,
  aoi,
  pop,
  n_vir,
  m_seg = 100,
  calc_energy = e_walkDrive_pop
)

Arguments

model_name	character, name of the drtm.
aoi	sf, polygon of the Area of Interest (AOI).
pop	sf, centroids of a hectaraster population dataset covering the full extent of the 'aoi' input (column name for population must be 'n').
n_vir	numeric, number of the virtual stations to place.
m_seg	numeric, resolution of the road segmentation in meters.
calc_energy	function, energy calculation function.

Value

A demand responsive transport model of class 'drtm'.

Examples

# Example data
aoi <-
  sf::st_read(system.file("example.gpkg", package = "drtplanr"), layer = "aoi")

pop <-
  sf::st_read(system.file("example.gpkg", package = "drtplanr"), layer = "pop")

# Create model
m <- drt_drtm(
  model_name = "Jegenstorf",
  aoi = aoi, pop = pop,
  n_vir = 10, m_seg = 100
)
m
