Why does air quality affect transportation?
Construction of wider roads reduces congestion temporarily. Once congestion is reduced with additional lanes, the roadway becomes more attractive to motorists until saturation is again reached. The addition of a project can also increase congestion on connecting roads. While congestion does contribute to pollution problems, it also serves as a means to deter added vehicle miles traveled. Thus, there is a need for transportation professionals to explore alternative forms of transportation.
