Details
Both data sets are square matrices of dimension (121, 121). If D is one of
the matrix, D[i,j] is the distance from city of id rownames(D)[i] to city
id colnames(D)[j] expressed in meters (french_cities_distances) or in
minutes (french_cities_times). The distance is measured along the fastest
path from i to j on the French road networks as computed using
OSRM engine (see details below). Ids in
column and row names can be used to get information on the cities in the
french_cities data set (column id). Rows and columns are sorted in
decreasing population order, as in french_cities. Note that the matrices
are not symmetric.
Distance calculation
The distances and durations have been computed using the OSRM engine in version 6.0.0.
Calculations are based on the car profile included in OSRM sources for
the 6.0.0 version.
