Band 6+: The table below ahows the number of hours' delay experienced by commuters in different-sized cities between 1995 and 2015 (with predicted for 2025)

The table represents how many hours of delay were witnessed by commuters in different-sized cities from 1985 to 2015 (with projections until 2025).

Overall, it can be seen that the most hours of delay were experienced by commuters of metropolis cities, whereas the least hours of delay were recorded in small cities. In addition, metropolis cities had large figures in all given years and expected to continue in future also.

To begin with, the residents of small cities experienced a delay of 7 hours in 1985, which increased to three times higher in 1995 and 2015 (21 hours). By contrast, metropolis cities delay were 60 hours, which was the highest among all other cities, and it may decrease to 40 hours in 2025, compared to double that of projection for small cities (20 hours).

In terms of medium cities that witnessed 9 hours delay in 1985, and 31 hours in 2005, which expected to fell nearly half (15 hours) by 2025. Nevertheless, medium cities experienced relatively high hours in 1995, 2005, and 2015, stood at 38, 42, and 36 hours, respectively, which can decline to 30 hours in the predicted year.
