The line graph illustrates the average number of daily journeys taken by different types of transport—namely bus, train, subway, car, bicycle, and on foot—in one country during the years 1985 and 2015.
Overall, while bus usage significantly declined over the period, other forms of transport such as car, subway, and walking saw increases. The car became the most popular mode of transport in 2015, whereas buses experienced a substantial drop in daily usage.
In 1985, buses were the most commonly used mode of transport, with around 60,000 daily journeys. However, by 2015, this number had fallen sharply to 40,000. In contrast, car usage increased from approximately 30,000 to 35,000 journeys per day, making it the most frequently used transport mode by 2015.
Train and subway journeys both rose modestly. Train use increased from around 6,000 to 8,000, and subway journeys rose from roughly 13,000 to 20,000. Bicycles, although the least used in both years, saw an increase from 7,000 to 20,000 daily trips.
Walking (on foot) also became significantly more popular, growing from about 25,000 journeys in 1985 to 40,000 in 2015, matching the number of daily bus trips by the end of the period..
