^*Local arrangements in place on islands for short-distance drop-off to ferry terminals. Number in brackets indicates the quantity of these transfers. ITT in-transit time, V van, B bike, D UAV/drone.
Results extracted from parameter sweeps, meaning other solutions that offer a compromise of these extremes may also exist.
