The traffic hubs evaluated here contain many noise sensitive areas such as those surrounding schools, universities, hospitals and outpatient clinics. Some of these institutions were therefore selected for a more detailed evaluation based on acoustic maps of the noise levels reaching the facades of these buildings. Two hospitals were selected in the noise sensitive areas: a) Hospital 1 in Stretch 1, and b) Hospital 2, in Stretch 3 (see Fig. 2). The sound levels that reach the facades of hospitals were hypothetical measures aimed at reducing the aforementioned noise levels reaching the hospital facades. These hypothetical situations are identified as Scenarios 1, 2 and 3, and are described below.
