In an environment characterised by increased transport capacity, road transport is growing partly as a matter of course; however, this growth is also due to other factors. The first explanatory factor is a modal split that is more favourable to road transport. The second stems from the shift from private to public transport. The third is due to the changing nature of trade, which is increasingly favourable to road transport. Over the long term, road transport markets tend to focus primarily on the most promising and most lucrative products. These include agri-food products and manufactured goods, which now account for around two-thirds of total road freight transport flows.
