The line graph gives information about how many tonnes of goods were transported in the UK from 1974 to 2004 via four various means of transit.
Overall, data suggest that economic activities of the UK increased throughout the period; the volume of commodities delivered across all researched forms of transport went up generally. Additionally, the tonnage of goods carried by road remained the highest over the period in question.
In detail, the weight of products conveyed through road and pipeline started off at around 70 and 5 tonnes respectively. The figures then rose, albeit at varying degrees, with road conveyance reaching a chart high of under 100 tonnes and pipeline making up over 20 tonnes in the next century.
As for the quantity of goods delivered by waterways and railways, the numbers began at similar levels of 40 tonnes in 1974, after which the former experiencing a noticeable growth and the latter declining markedly over the next four years. The indicators of water transportation then levelled out at under 60 tonnes by 1994 prior to a slight decrease to 55 tonnes in 1998, after which it grew marginally to 62 tonnes in 2002. Meanwhile, the tonnage of goods conveyed by rail underwent some mild fluctuations, and recovered to its initial point in 2002.
