The given line graph depicts the quantities of goods transported in the UK between 1974 and 2002 by road, water, rail, and pipeline.
Overall, road transport showed a continuous increase with minor fluctuations, water transport experienced fluctuating levels with a peak in 1994, rail transport exhibited a general upward trend after a brief decline, and pipeline transport demonstrated a remarkable growth with some fluctuations.
In 1974, road transport accounted for approximately 70 million tonnes, and it gradually increased to reach a peak of around 100 million tonnes by 1998. However, there was a slight decrease to just below 100 million tonnes by 2002. Water transport began at slightly above 40 million tonnes, fluctuated with a peak at around 60 million tonnes in 1994, and ended around 58 million tonnes in 2002. On the other hand, rail transport started at roughly 40 million tonnes, dipped to about 30 million tonnes by 1982, and then steadily increased, reaching a peak of approximately 42 million tonnes in 2002.
On the other hand, pipeline transport commenced with the lowest quantity in 1974 at approximately 5 million tonnes, then experienced a sharp rise to about 20 million tonnes by 1978, followed by a steady growth to nearly 25 million tonnes in 2002. Throughout the period, pipeline transport showed consistent growth with some fluctuations, establishing it as a noteworthy mode of goods transportation in the UK.
