The pie charts compare the modes of transportation used by daily travelers in the capital of England during 1990, 2000, and 2010.
Overall, the most used transportation was underground railway, which consistently had the highest proportion. Whereas, a modest percentage used motorcycles for traveling to work as the least used vehicle.
In 1990, underground railway remained the highest point of the chart with nearly four-tenths of commuters; though this proportion decreased slightly by 4% to 34% after 20 years, this alteration did not affect its rank. Train and car were equally popular in 1990, which accounted for 24% and 22%, respectively. Furthermore, both remained relatively unchanged over the twenty-year period, declining marginally by 1-2% commuters. Meanwhile, a minority of people who chose to walk to work peaked at 10% in 2000, before plummeting to 9% in 2010.
On the contrary, motorcycles and bicycles were the least widely used transportation, which was significantly lower at only 4% at the beginning of the period. Nevertheless, by 2000, while bicycles doubled to 8%, motorcycles still stayed stable at 4%. On the other hand, the proportion of daily travelers preferring using motorcycles grew moderately to 5%, while bicycle usage further constituted a tenth of commuters in 2010.
