The charts show the world traffic volume measured in passenger-kilometer-miles

These pie charts provide a breakdown of traffic volume in the world measuring in passenger-kilometer-miles from 1990 to 2020 and try to predict its changes for 30 years later, in 2050. Overall, enormous boom in amount of traffic is obviously evident in the charts. Meanwhile, the proportion of high-speed transport shows a significant increase, it can be seen that the percentage of utilizing automobiles will decrease gradually. In 1990, more than half of total traffic volume, 23. 3 trillion pkm, allocated to automobiles (53%). Also, The second popular transport system was buses by 29%. However, rail way and high-speed transport had similar portion (9%). After 30 years, using of various transports had shown a steady growth, it became more than twice, about 53trillion pkm. Despite this increase, automobiles demonstrated a significant go back by 10 %. Whereas, figures illustrated that high- speed had took up significant percentage of this sector. On the other hand, People’s tendency commuted with rail way and buses had decreased by 3%(6% and 26% respectively). As might be expected, the prediction for 30 years later gives the first place of transportation to high- speed, even though cars will save its serious role in transport system yet.
