The bar graph shows the distribution of four means of transport in a European City. Data have been collected in a 20 year gap in between 1960 and 2000.
It can be seen how across the years the most preferred transport modes shifted from foot to car, leaving the bus statistics oscillating, and bike ones decreasing together with walking.
It appears obvious how people preferences changed during these 40 years: car transport in 1960 was the less preferred one, with just 5% of overall travellers choosing it, while in 2000 it got very popular, reaching the 35%. This growth is followed by a drop in the usage of bike, which went from 25% down to 5%. The same decreasing trend is shown by foot transport, which dropped from almost 35% to a bit below 10%.
While the others means of transport experienced a clear increase or decrease, this can't be said for the bus: in fact it oscillated around 20% of users over all the travellers.
