The modes of transport in Iceland are governed by the country's rugged terrain and sparse population. The principal mode of personal transport is the car. There are no public railways, although there are bus services.[1] Transport from one major town to another, for example Reykjavík to Akureyri, may be by aeroplane on a domestic flight. The only ways of getting in and out of the country are by air and sea. Most of the country's transport infrastructure is concentrated near the Capital Region, which is home to 64% of the country's population.[2]
