Distance versus travel time in intra- and international bilateral links. Notes: Average excess distance is the %-ratio between road distance and great circle distance, both in km. Avg. road speed denotes the average travel speed on the fastest road connection, in km/h, while avg. direct speed refers to the average theoretical speed on the most direct (= great circle distance), in km/h.
