Overall, all the ways saw an increase in popularity except for the railway, which remained at 40 million tons. Moreover, pipelines and road reserved their rank at the end of the period as the least and most popular ways, respectively. However, the waterway experienced considerable growth.
At the beginning of the period, road by transporting nearly 70 million tons in 1974 is in the first place the same as in 2002 with approximately 98 million tons. On the other hand, pipeline shows the lowest amount throughout the period. The transported amount of goods by water was almost constant from 1974 to 1978 when revealed an exponential rise to nearly 60 million tons, which plateaued for about 20 years before starting to rise gradually again.
The amount of transported goods by rail generally declined, between 1978 and 1998 compared to the four-year periods in the beginning and end. Interestingly, all the methods were in a drop, in 1994, yet the pipeline peaked at this year.
