The line graph illustrates the number of people who used eco-friendly modes of transport from 1980 to 2030, measured in millions of commuters.
Overall, it is clear that the subway had the highest usage throughout the period. Conversely, bike sharing had the lowest number of commuters and remained relatively stable, while bus usage declined over the given time frame.
Focusing on the subway and tram, both experienced an upward trend. Initially, the number of subway commuters was around 2.5 million and remained stable until 1990. However, it continued to be the dominant mode of transport throughout the period, reaching its highest point in 2030 at 4.5 million. Similarly, tram usage increased steadily from 0.5 million at the start and peaked at 1.5 million in the final year.
On the other hand, bike sharing had the lowest number of users, as it only started in 2000 and increased gradually. After 20 years, its usage stabilized at approximately 0.5 million by the end of the period. Meanwhile, bus transportation had around 1.5 million commuters at the beginning, placing it in the middle range. However, its usage declined steadily over time, dropping to around 1 million by 2030.
