This science fair project was performed to compare traffic flow and pollution emission at different times of the day. The observation was done on a highway by monitoring the average speed, amount of vehicles and the flow of traffic.
1. For this science fair project, the independent variable is the time of the day traffic is monitored. The dependent variables are the vehicle speed, traffic volume and traffic flow. This is determined by observing the video recording. The constants (control variables) are the chosen location, the day of the observation and the viewing range of the video recording. 2. Choose a raised location along a highway with a 90km/h speed limit. Set up the video camera and adjust it to capture an unobstructed view of a 200m stretch of the highway. 3. Set the timer in the video camera .....
