- The total weight of goods carried by road has changed relatively little since 1970, but freight traffic (tonne kilometres) has risen by 85 per cent and the energy consumed in transporting goods by 144 per cent. This reflects transportation over greater distances, and of bulkier, but less dense goods - offsetting efficiencies such as the use of large articulated vehicles.
- Since 1998, there has been relatively little change in the energy, tonne kilometres, tonnes lifted and percentage share of articulated vehicles over 33 tonnes.
