Air transport efficiency and its measures

There are various definitions of efficiency of transport and different methods of measurement. This makes it difficult to measure and carry out benchmarking assessment of different modes. This paper presents proposals for measuring the efficiency of transport systems, taking as criteria: travel time, energy consumption, material use, impact on environment, affordability and accessibility. Based on these criteria, a benchmarking analysis of road and air transport was carried out. A new proposal for general definition of efficiency of transport is presented.
