The line graph presents a comprehensive overview of the quantities of goods transported in the United Kingdom via four distinct modes of transport—road, water, rail, and pipeline—over a span from 1974 to 2002.
In general, road transport emerged as the dominant mode throughout the period while pipeline transport consistently accounted for the lowest volume of goods transported.
In 1974, the volume of goods transported by road was approximately 70 million tonnes, demonstrating a steady upward trajectory until it reached its peak of around 100 million tonnes in 1998, before experiencing a minor decline to just below 100 million tonnes by 2002. Water transport commenced at approximately 40 million tonnes in 1974, exhibiting fluctuations with a notable peak of 60 million tonnes in 1994, eventually concluding the period with a modest total of around 58 million tonnes in 2002. In contrast, rail transport started at nearly 40 million tonnes, experienced a decline to approximately 30 million tonnes by 1982, but later witnessed a gradual recovery, culminating at about 42 million tonnes in 2002.
Pipeline transport, despite beginning at a mere 5 million tonnes in 1974, demonstrated a significant upward trend, reaching 20 million tonnes by 1978, and continued to show consistent growth, finally attaining approximately 25 million tonnes by 2002. Overall, while road and water transport exhibited prominent fluctuations and growth, rail and pipeline transports displayed more modest increases, with pipeline transport remaining the least utilized mode for the movement of goods throughout the examined period.
