The given two pie charts compare the percentage of four different modes of transportation, namely car, bus, bicycle, and walk, chosen by people in the years 2008 and 2018 in Cambridge, UK.
Overall, there was a clear shift in transport preferences between the two years. The use of cars, which dominated in 2008, declined significantly by 2018, while walking and cycling gained popularity. Meanwhile, bus usage remained constant over the decade.
Between 2008 and 2018, the proportion of people walking rose markedly from 11% to 20%, nearly doubling over the ten-year period. Similarly, the percentage of bicycle users also experienced a noticeable increase, climbing from 17% to 30%. This made bicycles the most preferred mode of transport in 2018, tripling the proportion of walkers and surpassing all other categories.
In contrast, the use of cars declined sharply. In 2008, 42% of people traveled by car, which was the highest proportion among all modes. However, this figure dropped to 25% in 2018, representing a fall of 17 percentage points. This decrease means that by 2018, car usage had fallen to the same level as buses and significantly below bicycles. Interestingly, the proportion of bus users remained unchanged at 30%, indicating a stable preference for public traánport.
