The line graph illustrates the number of products which were delivered by different ways of transportation in the UK from 1974 to 2002.
Overall, the quantity of goods transported on the road remained the highest while the number of products delivered on the pipeline remained the lowest between 1974 and 2002. During the given period, the amount of goods transported on the road, waterway and pipeline increased steadily while the quantity of products delivered on the railway fluctuated and returned to the approximately beginning value in 2002.
In 1974, roadway was the most common modes of transport with about 70 million tonnes of goods shipped. In contrast, only 5 million tonnes of products were delivered on the pipeline, which was 14 times as low as the quantity of goods transported on the road. Meanwhile, waterway and railway were used to transport the same number of products in the same year, about 38 million tonnes, which was 30 million tonnes lower than using roadways.
In 1990, the number of products transported on the roadway increased to 80 million tonnes. Also, the quantities of goods using waterway and pipeline for transportation showed gradual rises to 59 million tonnes and 17 million tonnes respectively. However, fewer products were delivered on the railway with approximately 38 million tonnes in 1990. In 2002, the amount of goods shipped by roadway reached the highest point at 97 million tonnes, which was five times as high as the number of products transported on the pipeline. Between 1995 and 2002, pipeline was used to deliver almost the same value of goods of around 20 million tonnes.
