The graph illustrates a comparison between real proportion of buses arriving on time and the target set by bus company. In addition, second graph represents the number of complaints per thousand journeys made by the passengers.
Overall, it is noticable that target set by companies was higher than actual percentage of arrived buses. In contrast, passengers complaints figure fluctuated over the period, but in the end showed an upward trend
In 1990, approximately 83% of buses actually arrived in time, slightly below the target of 84%. Although the small decrease to 82 % in 1993, it then noticeably increased to 84.5 % in 1996. Subsequently, the number reamained unchanged until 2002, when it slightly rose to 86 %. Moreover, it was the only year when actual arrives overtaked the target by 1 %.
In contrast, the second graph detailing the figure of complaints per 1,000 passenger journeys. Starting with about 50 complaints in 1990, the number increased slightly to 100 in 1993. However, the number rose again in next years, reaching 120 in 2002.
