The bar chart illustrates the number of journeys made by buses and the subway in Williamsville throughout the five-year period. Overall, the figure for underground transport passengers showed a steady upward trend whereas bus usage fluctuated slightly during the period. It is also noticable that the gap between the two modes of transport widened gradually over time.
In 2011, approximately 400,000,000 bus journeys were recorded, compared to 600,000,000 trips by rail transport. Bus usage rose marginally in 2012 before declining in 2013. It then recovered in 2014 and ended the period at around 420,000,000 passenges in 2015. Despite a slight growth in 2012 and 2014 bus transport remained significantly less popular than the subway.
By contrast, the number of subways passengers grew consistently from 600,000,000 in 2011 to about 750,000,000 in 2015. Growth was particularly marked after 2013, suggesting that underground transport became increasingly attractive to residentsduring the latter part of the period.
