Due to the comparatively high rate of personnel expenditure of up to 72% in the road transport sector, the differences concerning total costs between the European countries appear relatively high. For example, an average road transport operation in Sweden is more than three times more expensive than a comparable shipment in Bulgaria.
Also while the fuel share of the total costs varies from 9%-32%, it remains the subordinate factor compared with personnel expenditure, even with the evident price increase in more recent years. Only in Bulgaria and Romania does the fuel share represent the most important cost factor.
