The line chart details the percentage of registrations for three types of commercial vehicles: trucks, taxis, and buses in the US during 40 years, starting from 1970.
Overall, there was an upward trend in a percent of individuals using taxis, while the statistics for the other vehicles witnessed an opposite pattern. In addition, truck registrations, as the most dominant type of commercial vehicle, maintained the highest share throughout the period, with figures in both 1970 and 2010 exceeding all others on record.
Looking first at trucks and buses, trucks accounted for the largest proportion among the three types in 1970, at around 50%, except in 1980, when taxis briefly overtook them. After that, truck registrations rose steadily and reached 45% in 2010. In contrast, the proportion of buses was the lowest throughout the period. It increased from 5% in 1970 to 15% in 1980, then fell significantly to 4% by 2010.
The proportion of taxis started at about 22%, after which it reached a peak of 35% in 1980, surpassing the data of trucks remaining in the last 10 years. Furthermore, taxis experienced a sudden drop of 20%(from 35% to 15%) in the proportion of vehicle registration between 1980 and 2000. Over the period of 10 years, taxis experienced rapid growth in the percentage of use in the UK, nearly 35%.
