The two bar graphs compare data in the actual proportion of buses arriving on time and company’s target, along with complaints per thousand passenger journeys in five different years from 1990 and 2002.
Overall, it is clear that the percentage of actual arrivals on time reached its highest point in 2002, while except in 1990, the company’s target remained the same throughout the period. Despite the improvement in bus punctuality, the number of complaints rose significantly over the period.
Regarding the actual and target percentages of buses, the highest proportion of actual buses arriving on time stood at 85% in 2002, whereas in 1993, the punctuality rate was the lowest, at 82%. In 1996 and 1999, both years recorded the same value of 84.5%. Arriving on time was a modest 83% in 1990. In addition, except in 2002, actual arrivals on time were lower than the target during the 12-year period.
In case of the passengers’ complaints, the highest number of complaints was approximately 120 (per 1000 passenger journeys), while it was the lowest in both 1990 and 1996, at around 55 per thousand. In 1999, the complaint rate was lower than in 2002, at around 110 per thousand. Additionally, 1993, complaints reached 100 per thousand.
