A Methodology for the Definition of the Acoustic Capacity of a Road Infrastructure

In this paper, a new methodology for the assessment of the so-called “acoustic capacity” of a road infrastructure is proposed. This aspect is very important in the field of transportation planning as, currently, road infrastructures are verified only in terms of physical capacity; at most, the envir...

The acoustic capacity is assessed based on the Harmonoise model, which is widely recognized at the European level.
