The diagram showing the significant charts of how much people use subway for their transport within 40 years in some cities such as city A, city B, and city C. We could see from the start, in 1980 city A already reach the highest and also ended it with still being the highest. Instead City B and City C still have lower passangers.
Firstly, City A started with 158 passangers in 1980. They were going steadly until they developed 32 more passangers or in detail is 180 passangers in year 2000, so it’s a 20 years long to reached it. But didn’t stay long that they fell into 160 passangers in just a couple of years after. City A learned their lesson, they keep going upper after that until in 2019, they jumped up high from 160 passangers to 250 and more passangers and this time they managed to keep it well until the end.
The charts doesn’t only show about city A, it also shows about city B and city C but they just didn’t as lucky as city A. City C started at below 50 from city B, it keeps going little upper but then fell a little from 1980 until 2018, that in 2019 city C having been enhanced their passangers and beat city B. Meanwhile city B started at 100 passangers in 1980, sadly city B passangers is decreasing. But in 1990, the number of their passangers is increased. But just likely their past, their passangers weakened until the end, in 2020 city B is the lowest city that has the numbers of passangers im subway.
