The provided line graph illustrates the quantity of goods transported via various modes of transportation in the United Kingdom from 1974 to 2002.
Overall, road transport was the most dominant, with consistently high tonnage throughout the period, while pipeline transport had the lowest utilization. Water transport fluctuated within a certain range, and rail transport displayed a steady increase, except for a dip during the period.
Road transport emerged as the predominant method, with an initial volume of around 70 million tonnes in 1974, escalating steadily to a peak of nearly 100 million tonnes by the end of the period. In contrast, pipeline transport started at about 5 million tonnes, experienced minimal growth, reaching roughly 22 million tonnes post-1974, and remained stagnant thereafter.
Additionally, the quantities transported via road, water, and pipeline experienced continuous growth over the years, starting around 70, 40, and 5 million tonnes in 1974 respectively, and reaching peaks of approximately 98, 65, and 22 million tonnes in 2002. Conversely, rail transport depicted fluctuations, hitting its lowest point of about 25 million tonnes just after 1994.
