“Freight road transport in Spain.Towards a higher energy and environment efficiency?” Pedro José Pérez-Martínez
BACKGROUND TRANSPORT SECTOR IN SPAIN • Supports economical development • 5,3% GDP (3% road transport, rail excluded) • Multypling effect over other sectors • Employment: 4,3% potencial working popullation and 4,7% working people. (Road transport, rail excluded, represents 3,2% working people).

CONCLUSIONS • Benchmarking of transport description, utilisation, productivity and efficiency in road freight in Spain vs set of indicators was done using PRFSS • Benchmarking reveals wide variation in absolute values during studied period 1997-2003 • Benchmarking indicates not a wide variation in vehicle utilisation, productivity and energy intensity although not distinction in the nature of the product was done • Limitation of the survey, lack of key performance indicators that directly measures operating performance (KPI2-KP3) • Future surveys should examine more KPIs and further relationship between transport and logistical variables (also interraltionship between KPIs) • Expand sample size permiting greater segmentation, more number of homogeneous strata, improving the accuracy
