The line chart illustrates the quantities of goods transported using four transport modes in the United Kingdom from 1978 to 2002. Overall, all transportation forms fluctuated over the period, and roads saw the most pronounced increase in usage until the last period.
The amount of goods transported by road in 1974 started at around 70 tons, and it slightly increased to about 75 tons in 1978. In 1982, this figure minimally declined to approximately 65 tons, then gradually rose to 83 tons between 1986 and 1990. In 1994, there was a small decline of about 79 tons, which then peaked at under 100 tons in the last period. Additionally, the number of items transportable by water began at under 40 tons in 1974. From 1978 to 1982, there was a slow improvement of approximately 75 tons, and it fluctuated during 1986 until 1998, then moderately improved to over 60 tons in 2002.
On the other hand, from 1974 to 1978, the quantities of items transported by rail stayed constant at 40 tons, then there was a slight decrease to around 30 tons in 1982. It fluctuated between 30 and 35 tons between 1986 and 1994, and in the end, it gradually rose over 40 tons. Moreover, during the period spanning 1974 to 1990, the number of things transportable by pipeline gradually went up, starting from about 5 to under 20 tons. Then there was a minimal growth to under 20 tons and stabilized at approximately 23 tons in 2002.
