The report concerns a line graph , that compares the amount of nitrogen dioxide emitted by four different types of transport .
It is the evident that buses produce most of the discharges, while diesel car in opposite had the most lower expenses . But what interestingly that lorries car following very close behind a buses, whereas petro; cars are a little higher diesel. Another interesting fact is that all four types of transport start and end with the same speed
Delving deeper into the details from graph of buses, it can be seen that there are a stable declining in the amount of emissions but improvement in speed from 40 grams and 10 km speed to 25 grams and 60 km . Further there is a dramatic increase and buses finally reach its peak with mass of 41 grams and 130 km. The lorries has relatively the same situation , there is a constant fall from 32 grams to 15 grams and 90 km. But in the contrary of buses in this case there is not a dramatic increase , just a gradual rise until the point of almost 25 grams . Petrol and diesel cars has difference approximately on 5 during all changes. Petrol has the higher rate of emissions and in the outset it has 10 grams , the trend in both categories of cars has subtle changes but , it can be seen that petrol cars at towards the end increase its amount to about 10.2 , meanwhile diesel is stable and has some fluctuations only in the beginning.
