The bar chart shows the changing patterns of transport use in a European city during the period from 1960 to 2000. In brief, the chart shows that the use of the car as a means of transport dramatically increased over the period shown, while the others fell.
In detail, in 1960 the motor car was used least as a method of transport with only about 7% of the population using this method but car use grew steadily and strongly to finally reach about 37% of the population by 2000. This was a massive 5-fold increase in use.
Over this same period, however, the popularity of walking, which had been the most popular means of transport with 35% of the population in 1960 having it as their preferred way of getting around, fell to 10%. Bicycle use also fell from a high of about 27% in 1960 to just 7% in 2000.
On the other hand, bus use was more erratic being popular with almost 20% of the population in 1960 and rising to a peak of about 27% in 1980 before falling back to about 18% in 2000.
