configure_graph: Graph configuration

In douglascm/trafficr: Traffic Assignment Methods

Description

Tranforms network data from source network and zones

Usage

configure_graph(
  network,
  zones,
  turn_penalty = F,
  left_side = F,
  addvalue_cols = F,
  weighted = F,
  performance_measures = F,
  use_cost_col = F
)

Arguments

network	sf object containing network data
zones	sf object containing zone data
turn_penalty	Adds turn penalty (see dodgr documentation on turn penalty from function 'R/weight-streetnet.R')
left_side	Does traffic travel on the left side of the road (TRUE) or the right side (FALSE)? - only has effect on turn angle calculations for edge times. (see dodgr documentation on turn penalty from function 'R/weight-streetnet.R')
addvalue_cols	Does network shapefile has columns 'addv_fw' and 'addv_bw' for added cost in links? (TRUE) or (FALSE)
weighted	Does network shapefile has columns 'wg_fw' and 'wg_bw' for a cost multiplication factor in links? (TRUE) or (FALSE)
performance_measures	Does network shapefile has columns 'alpha' and 'beta' for usage on BPR funcion? (TRUE) or (FALSE)
use_cost_col	Use time column as cost (opposite to speed and distance)? (TRUE) or (FALSE)

Value

graph object ready for usage on solve_ue() function

Examples

flist <- configure_graph(sioux_network,sioux_zones,use_cost_col=TRUE)
graph <- flist[[1]]
zones <- flist[[2]]
