osrmTableOD: Get Travel Time Matrices Between Origins and Destinations

Description

Build and send OSRM API queries to get travel time matrices between set of origin points and set of destination points

Usage

osrmTableOD(dfo, ido, xo, yo, dfd, idd, xd, yd, limit = 100)

Arguments

dfo

data frame containing origin points identifiers, longitudes and latitudes (WGS84).

ido

identifier field in dfo.

xo

longitude field in dfo.

yo

latitude field in dfo.

dfd

data frame containing destination points identifiers, longitudes and latitudes (WGS84).

idd

identifier field in dfd.

xd

longitude field in dfd.

yd

latitude field in dfd.

limit

table query limit of osrm API in use. The default value (100) is the public API limit.

Value

• A matrix of time distances (in minutes) between origins and destinations is returned.

Examples

# Load data
data("com")
# Travel time matrix
distcom <- osrmTableOD(dfo = com[1:50,], ido = "comm_id", xo =  "lon", yo =  "lat", 
                       dfd = com[51:100,], idd = "comm_id", xd = "lon", yd = "lat")
# First 5 rows and columns
distcom[1:5,1:5]
