Generally, it could be obviously witnessed that bus performance of this company behaved better than expected during this period, except in 2000, when the actual punctuality rate of buses was lower than the target percentage. Moreover, the number of complaints from passengers experienced a relatively stable surge between 1999 and 2003.
Upon closer examination of the data, the target percentage of buses arriving on time steadily decreased, from 80% in 1999 to around 35% in 2003.

In addition, the number of complaints declined slightly in 2001 but increased steadily in the next two years and eventually reached its peak in 2003, with approximately 120 complaints.
