streetnet_traveltimes: Calculate travel times on a street network

In triply-at/gtfsmulti: Creating, storing and analyzing multi-modal transportation networks

Description

Calculate travel times on a street network

Usage

streetnet_traveltimes(x, od_pairs, ...)

## S3 method for class 'sfnetwork'
streetnet_traveltimes(
  x,
  od_pairs,
  time_column = "time",
  weight_column = "weight",
  ...
)

## S3 method for class 'dodgr_streetnet'
streetnet_traveltimes(x, od_pairs, ...)

## S3 method for class 'dodgr_streetnet_sc'
streetnet_traveltimes(x, od_pairs, ...)

Arguments

x	The street network as an object of class sfnetwork, dodgr_streetnet or dodgr_streetnet_sc.
od_pairs	A data.table object in which each row contains the origin and destination location of a route for which the travel time needs to be calculated. The table should contain the columns from_lon, from_lat, to_lon and to_lat containing respectively the longitude and latitude coordinates of respectively the origin and destination.
...	Ignored.
time_column	Name of the column in the edges table of the street network that contains the travel time values for each edge.
weight_column	Name of the column in the edges table of the street network that contains the weight of each edge. These value are used to find the shortest path (i.e. the path with minimum weight) between an origin and a destination.

Value

An integer vector of travel times in seconds for each of the given OD pairs.

Note

Coordinates should be expressed in coordinate reference system EPSG:4326. The function assumes this to be true, and does not check for it.
