The charts below show the information about a US bus company between 1999 and 2003.  Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The pie charts illustrate the comparison between the actual and

target

punctuality

rates of buses from 1999 to 2003 and depict the number of

passenger

complaints during the same period.

Overall

, it is evident that the

target

performance for bus

punctuality

declined gradually over the years,

while

the actual performance experienced fluctuations but eventually nearly matched the

target

rate

in 2003. Meanwhile, the number of

passenger

complaints showed a steady upward trend throughout the five-year period. In 1999, the actual

punctuality

rate

was close to the

target

, with both hovering around 80%.

However

, in 2000, the actual

rate

dropped significantly to approximately 30%,

whereas

the

target

rate

remained stable at around 40%. The years 2001 and 2002 saw the actual performance stagnate at just below 40%, closely aligning with the

target

. Remarkably, in 2003, the actual

punctuality

rate

surged back to nearly 78%, creating the largest discrepancy between the actual and

target

rates over the entire period. Simultaneously, the number of

passenger

complaints increased consistently from 60 in 1999 to 120 in 2003, doubling over the five years.

This

suggests a correlation between the fluctuations in bus

punctuality

and the rise in

passenger

dissatisfaction.
