Introduction
Transport demand can be measured either by final energy consumption or in terms of km travelled. For km travelled, personal travel is measured in passenger-km and freight in tonne-km.
Mode is usually distinguished, i.e. road/rail/river/air/sea.
Time series can be approximated by e.g. measuring stations on roads.
Europe
