The line graph illustrates the percentage of commuters who travelled to work by car, bus and bicycle in a European city across the three decades from 1990 to 2020.
Overall, the car remained the most widely used mode throughout the period, despite losing ground towards the end, whereas cycling rose steadily and eventually overtook the declining bus.
In 1990, half of all commuters relied on cars, a figure which climbed gradually to peak at 62% in 2010. Thereafter, car use went into decline, slipping back to 55% by the end of the period. Bus travel, by contrast, followed a consistently downward path, falling from 30% in 1990 to just 20% three decades later.
Cycling presented a markedly different trend. Having accounted for a mere 8% of journeys in 1990, it crept up to 16% in 2010 before accelerating sharply to reach 27% by 2020. This represented more than a threefold rise over the period and, notably, left cycling well above the figure for buses, which it had already surpassed.
