Clair City: Traffic Survey

Where does air pollution come from and what causes it? Traffic Survey invites pupils to investigate. By organising, representing and interpreting data, pupils explore in depth the link between traffic and pollution levels.

Across Europe, traffic is a major cause of air pollution, especially NOx. This comes from diesel and petrol engines, with diesels being worse.

Even though bigger vehicles (e.g. buses and lorries) produce slightly more of the gas, when there are lots of cars on the road it can cause a bigger proportion of the air pollution.

By conducting a traffic survey and analysing the results, pupils will hypothesise about the main issues.
