The line graph compares four different types of transport in terms of their monthly usage in a European metropolitan area from 1980 to 2030, including future predictions. Overall, while the usage of subway and tram showed a dramatic increase, bus usage recorded a significant decline over the same timeframe. Bike share, meanwhile, rose marginally.
The subway stood out as the type of transport exhibiting the largest growth in its usage compared to tram, bike share and bus. The rate showed an upward trend, elevating from 2.5 million to 3.5 million in 2020, by predicted climb to 4.5 million in 2030. During the same timeframe, bus, which initially had nearly 1.5 million users in 1980, saw its figure fall continuously to about 0.8 million.
In contrast, despite beginning at relatively low levels, both bike share and tram witnessed a growth in the number of commuters. The tram, starting at approximately 0.3 million commuters in 1980, saw a significant rise to about 1.5 millions in 2020, followed by future rise to 2.0 millions. Bike share, which was recorded at about 0.1 million commuters in 2000,is predicted to register marginal climb to 0.6 million in 2030.
