In a road case, we shall consider several points. We shall consider a minimum number of 1000 vehicles per hour N with a 50km/h minimum velocity (100km/h is the maximum velocity). Then we have a 68 dB(A) noise level at 10m from a lineal road (infinity length). The noise level will be,
in the lineal (infinite) road case.
In the curved road case, the program considers a finite element method of calculation. Each small size of road contributes to the total noise level. Each contribution will be given by
being a the angle of the small road size(degrees).
To obtain the total noise level, we add the different Li values following the equation
