The three pie charts compare the proportions of seven different modes of transport used by commuters in London across three specific years: 1990, 2000, and 2010.
Overall, the underground railway remained the most popular method of travel throughout the two-decade period, despite a slight decline. Conversely, the use of bicycles saw the most significant growth, while the reliance on cars and the underground railway generally trended downwards.
In 1990, the underground railway was the dominant mode of transport, accounting for 38% of commuters. This figure dropped slightly to 35% in 2000 and ended at 34% by 2010. Similarly, car usage started at 22% in 1990 but saw a gradual decrease to 20% in 2000 and 19% by 2010. The train remained a highly stable choice, hovering around 23-24% across all three years.
Regarding the less common modes of transport, bicycle usage doubled over the twenty-year period, rising from a mere 4% in 1990 to 10% in 2010. On the other hand, the percentage of people walking showed minor fluctuations, starting at 8% in 1990, peaking at 10% in 2000, and then dipping back to 9% in 2010. Motorcycles remained the least utilized option, staying consistently low at 4% to 5% throughout the period.
