It is often assumed that economic growth is automatically followed by freight transport volume increases. However, in this article it is argued that transport volume rises are usually linked to spatio-economic changes in economics. Transport distances grow much faster than economic output in tons. The article reviews price elasticity where road freight transport is concerned. Based on a few relevant studies, the conclusion is drawn that price elasticity probably lies between -0.7 and -1.1 which is much higher than is generally assumed. These findings, combined with certain theoretical and micro economic considerations, lead to the conclusion that spatio-economic patterns are rather flexible. The implication is that transport volume growth can be influenced to some extent. So, demand management could become a new element in freight transport policy. (A)
