The line graph to provides the information of how nitrogen oxide is emitted by ditterent vehicles at ditterent speed.
Overall, two vehicles emit the most nitrogen oxide which is buses and lorries and level of emission increases with speed. However, the emission of nitrogen oxide for diesel car and petrol car stayed constant no matter what speed it was in.
On the one hand, buses had an emission of 40 g/km at 10 kph speed which decreased constantly around 30 at 60 kph speed. As speed rose from 60 kph,the emission rose steeply to more than 40 g/km.Additional to that, the lorries had the similar trend like buses but it started and ended to lower level of emission than buses. On the other hand, petrol car and diesel car both showed similar trend, petrol car emitted around 10 g/km and emission of diesel car hovered around 5 g/km regardless of the speed.
