Air Pollution Science Fair Project

Pollution and Traffic Flow

Medium
Pollution and Traffic Flow | Science Fair Projects | STEM Projects
Do you want to know how traffic flow affects the release of pollutant gases? In this science project, you will observe a highway route with a speed limit of 90km/h and measure the vehicle speed, traffic volume, and traffic flow. You will analyze the data to see how the time of day affects the release of pollutant gases.

Hypothesis

The hypothesis is that air pollution will be the most severe in the early mornings and late evenings, during peak hour traffic.

Method & Materials

You will choose a raised location along a highway with a 90km/h speed limit. You will set up a video camera to capture an unobstructed view of a 200m stretch of the highway. You will divide the recording into 6 time windows of 3 hours each and observe the traffic speed, traffic volume, and traffic flow.
You will need a highway route with a speed limit of 90km/h, a video camera with a stand, a raised location to set the camera up and to view traffic, and a stopwatch.

Results

The results show that pollution emitted by vehicles is the highest during peak hours - 6am to 9am, and 6pm to 9pm. This proves that the hypothesis is true.

Why do this project?

This science project is interesting because it shows how traffic flow affects the release of pollutant gases. It also shows how good driving habits and a well-maintained car can help reduce pollution emitted on roads.

Also Consider

Variations of this science project include repeating the experiment with diesel-operated vehicles, like busses and trucks, to test for differences in the levels of pollutants emitted. The experiment may also be repeated in other areas, like more urban or residential areas, to test for differences in the levels of pollutants emitted.
