The graph below shows the quantities of goods transpprted in the UK between 1972 and 2000 by four different modes of transport.

As an introduction, the line graph demonstrates the number of goods transported through various methods in the UK, during the period between 1972 and 2000.

Overall

, the highest quantity of materials was transported by road,

while

the least amount by pipeline.

In addition

,

although

the usage of rail remained relatively constant over the duration, the other three types showed a gradually rising trend.

Firstly

, transport using roads steadily grew from 1972 to 2000 from about 70 to 100 with some fluctuations.

Likewise

, the use of water

also

had an increasing trend, which was at 40 in 1972, but approximately at 60 in 2000.

Furthermore

, delivering goods using pipeline, rose from almost 0 in 1972 to reach about 20 in 1980, and almost plateaued

thereafter

.

Moreover

, at the beginning of the period,transportation by roads and water remained the same at 20.

In contrast

, rails remained the same at about 40 from the beginning to end,

although

it showed some variations in between.
