The two graphs above present data about Japan’s train passengers and the punctuality of its trains between 2000 and 2009.
Overall, the number of people who took the train between 2000 and 2009 was all greater than 35 million people. However, from 2003 to 2005, there was a huge amount of increase. In general, the punctuality of the trains was not stable at all in these nine years between, which experienced two times largely increasing and dropped off.
Noticeable, in 2000 and 2006 only 92% of trains were running on time, which was way below the average. In the meantime, once the percentage went to the trough(92%), it started to have substantial growth to above the standard. From 2000 to 2004, this was the first growth period, after 2004 until 2006 have experienced a sudden drop-off. From 2006 to 2009 was the second growth period, and up to the peak of the trendline, which was 97 % of punctuality.
The first graph, compared to the second, is much more stable. The trendline was floating between 35 to 40 million population between 2000 to 2003. However, from 2003 to 2005, there was more population taking trains increased by 10 million people and reached a peak in 2005 of about 45 million. After 2005, the general trend started to fluctuate reductively to approximately 40 million people until 2009.
