The bar chart illustrates the average daily commuting time, measured in minutes, for residents of four Australian cities—Sydney, Melbourne, Brisbane, and Adelaide—from 2002 to 2010, at two-year intervals.
Overall, the amount of time spent traveling to work generally increased across all cities, with the exception of Adelaide, which experienced a fluctuating pattern. Notably, Sydney consistently recorded the longest average commute throughout the entire period.
In 2002, Sydney commuters spent approximately 35 minutes traveling to work, significantly higher than the other cities, with Melbourne and Brisbane averaging around 30 minutes, and Adelaide at roughly 27 minutes. Over the eight-year span, travel times in Sydney and Melbourne showed a steady upward trajectory, peaking at around 38 and 33 minutes respectively in 2010.
Brisbane followed a similar trend, with a moderate increase from about 30 minutes in 2002 to nearly 33 minutes by 2010. In contrast, Adelaide displayed no clear upward or downward pattern. After a slight rise in 2004, its average commuting time dipped in 2006, then rose again in 2008 before declining to approximately 27 minutes in 2010—almost identical to its starting point.
In summary, while most cities experienced a gradual rise in commuting durations, Sydney not only maintained the longest travel times but also saw the most consistent growth. Adelaide, on the other hand, remained the most stable, with minimal variation over time.
