The graph given below shows the quantities of goods transported in the UK between 1974 and 2002 by four different modes of transport. Summarize the information by selecting and reporting the main features

The given line graph illustrates in what ways products have been delivered in the United Kingdom from 1974 to 2002.

Overall

, we can see that road was the most used mode of transport during the 28-year period,

while

pipeline remained the least popular. In 1974, 70

million

tonnes

of goods were transported by road which means was recorded as the most popular one in that year.

This

figure

initially

had a slight fluctuation until 1990 when it started to rise, arriving

at the end

with nearly 100

million

tonnes

of product transported.  Both trains and boats accounted for 40

million

products.

This

figure

remained stable until 1978 when boats started to be a more common means of transporting goods than trains. Over the next 20 years, the latter

figure

fluctuated until 2002 when it reached the same amount of goods as the starting period. The former,

instead

, gradually increased arriving at almost 60

million

tonnes

, before falling significantly to 50

million

in 1998, and

then

rising again to over 60

at the end

of the period. Even though the least common type of transportation was the pipeline, we can see that

this

figure

had a very interesting pattern over the years. In the first four years, its number remained under 20

million

tonnes

, but

then

, in 1982, it dramatically increased to 25

million

tonnes

.

This

figure

plateaued before slowly declining to 20

million
