Roadway air dispersion modeling

Roadway air dispersion modeling is like a game where people try to figure out how air pollution will spread around roads. To play the game, scientists use a kind of computer program that can predict the way air pollution will move around a road, like a car or truck highway. To do this, they have to enter lots of information like the speed of the cars, the size of the road, and the type of air pollution. That helps the computer program figure out which way the air pollution will go so it can tell people which roads have the most dangerous air pollution. That way, people won't be breathing in air pollution like smoke or car exhaust too much and will stay healthy!
