Definition of Roadway noise
Roadway noise is the sound emanating from motor vehicles, collectively from tires contact on road surface, engine/transmission, aerodynamic forces, and braking elements, and specifically police, ambulance, fire-engine sirens, and exhaust pipes noise enhancers, car horns and music. Noise of rolling tires driving on pavement is found to be the biggest contributor of highway noise and increases with higher vehicle speeds.
In developed and developing countries, roadway noise contributes a proportionately large share of the total societal noise pollution. In the U.S., it contributes more to environmental noise exposure than any other noise source.
