The line chart presents the amounts of products that were delivered by road, water, rail and pipeline during 28 years since 1974.
The total number of objects transported by road and pipeline were initially 70 million tonnes and 5 million tonnes respectively. Between 1974 and 1994, both of them experienced a gradual increase. However, the story went on differently during the next 8 years after 1994. The data on road transportation rocketed from 70 million tonnes to almost 100 million tonnes while the number on pipeline transportation remained stable, with approximately 20 million tonnes.
When it comes to water and rail, the amounts of goods transported by them were similar, remaining 40 million tonnes during the period between 1974 and 1978. Nevertheless, since then, the figures showed a difference. Specifically, the number of water transportation had soared between 1978 and 1982, before becoming stable during the next 16 years. In 2002, the total number arrived at a climax, standing at 60 million tonnes. In contrast, the quantities of products that were transported by rail kept fluctuating before ending at 40 million tonnes in 2002.
