Transportation Indicators

Abstract

Transport energy consumption can be classified according to the types of transport (road, rail, air, inland waterways), or according to the area of use (passenger transport, freight transport). The indicators for the efficient utilization of energy are specific energy values, with the reference parameters of mileage (for private cars: vehicle-kilometres or vkm), and transport performance (passenger-km, pkm; ton-km, tkm). Structural influences within the sector of private cars (e.g. substitution of petrol by diesel engines) or of passenger and freight transport can be detected from changes in the demand relationships. The methods for calculating these structural effects are explained in Appendix A.4. National energy data used in this analysis deviate almost all from the Eurostat data.
