1. How to measure and analyze traffic noise?

3. Sources of Road Noise Vehicle noise
Engine, exhaust, acceleration, stop-and-go traffic condition, etc.
Road noise
Frictional noise between tires and road surface
Driver behaviour
Horns, loud music, shouting, etc.
Construction and maintenance
Presence of noisy and heavy machinery

4. decibel (dB)

7. Modeling Factors Vehicular Type

8. Distance of the receptor

9. Position of the Receptor

10. Traffic Volume

11. Speed

12. So on and so forth …

13. To do … We intend to develop a mathematical model to fit the noise data. Computer analyses and virtual experiments will be carried out based on the model.

14. A Proposed Model Q : Traffic volume in vehicles per hour
d: The distance from observation point to centre of the traffic lane
A, B and C are coefficients are to be derived for the investigated area by linear regression method based on LdB data taken at different traffic flows Q and distances d.
