The bar chart illustrates changes in the use of cars and bicycles for commuting over a five-year period from F to J.
Overall, car usage fluctuated significantly throughout the period, while bicycle commuting showed a general upward trend. Although cars were used far more frequently at the beginning, both modes reached the same level by the final year.
In year F, car usage stood at 900 before dropping sharply to a low of 450 in G. It then recovered gradually over the next two years, reaching a peak of 800 in I. However, in the final year, the figure declined again to 700. Despite these fluctuations, car usage remained higher than bicycle usage for most of the period.
By contrast, bicycle usage began at 400 and experienced a slight decrease to 350 in G. After that, the number rose steadily each year, eventually reaching 700 in J. This final figure was identical to that of car usage, indicating that cycling had become just as popular as driving by the end of the period.
