The given statistics compare the average annual distance in miles travelled by adults and different means of transport over the 30-year period, starting from 1977.
Overall, nearly half of the categories witnessed an upward trend, while walking, bicycles, motorcycles and buses took the opposite direction. Notably, by far the most common means of transport during the entire period was cars.
Regarding the first year of the period, cars was the most prevalent transportation method travelled by adults with around 3500 miles, which was quadruple the average annual distance by train and bus, at 900 and 800 miles respectively. Meanwhile, adults walked a total distance of 400, which was twice as much as the amount of distance travelled by taxi and fourfold that by bicycle and car.
Thereafter, there was a twofold increase to 7100 miles in the amount of distance travelled by cars in 2007, solidifying its position as the most common type of travel. The similar pattern was seen in trains and taxis, which rose by 100 and 600 respectively at the end of the period. Conversely, buses registered the most dramatic decrease to 500, while walking, motorbikes and bicycles slightly descended to 300, 90 and 80 respectively.
