The pie charts shows us the form of transportation to work, normally use by workers in a particular city and the changes that happened from 2005 to 2015. I think we have here downs and up.
In the first chart, work at home takes only 10% and it increased to 15% in 10 years. Also car alone went down from 50% to 35% ,because most of workers uses bus . Carpool has a little shake taking away 5% and making 20% in 2015. Bus increased only for 1% still has the same place. There are also bicycle and walk, bicycle increased from 5% to 10% in 2015. So that’s shows us that even cheapest things can be useful for everyday. And the last one walk stays in the same stage without changes.
In conclusion two graphs has changes and difference between years also there is downs.
