route_osrm

Plan routes on the transport network using the OSRM server

Description

This function is a simplified and (because it uses GeoJSON not binary polyline format) slower R interface to OSRM routing services compared with the excellent osrm::osrmRoute() function (which can be used via the route()) function.

Usage

route_osrm(
  from,
  to,
  osrm.server = "https://routing.openstreetmap.de/",
  osrm.profile = "foot"
)

Arguments

`from`	An object representing origins (if lines are provided as the first argument, from is assigned to `l`)
`to`	An object representing destinations
`osrm.server`	The base URL of the routing server. getOption("osrm.server") by default.
`osrm.profile`	The routing profile to use, e.g. "car", "bike" or "foot" (when using the routing.openstreetmap.de test server). getOption("osrm.profile") by default.
`profile`	Which routing profile to use? One of "foot" (default) "bike" or "car" for the default open server.

Examples

l1 = od_data_lines[49, ]
l1m = od_coords(l1)
from = l1m[, 1:2]
to = l1m[, 3:4]
r_foot = route_osrm(from, to)
r_bike = route_osrm(from, to, osrm.profile = "bike")
r_car = route_osrm(from, to, osrm.profile = "car")
plot(r_foot$geometry, lwd = 9, col = "grey")
plot(r_bike, col = "blue", add = TRUE)
plot(r_car, col = "red", add = TRUE)
