In the second scenario, we consider again an alarm originating at the concert area at 05:00 pm, but with an enabling
radius equal to 200 m. Clearly, the larger the enabling area is, the higher the infection rates are, as shown by Figs. 7 and 8.
However, by comparing Fig. 5 withFigs. 6 and 7 withFig. 8, respectively, it is easy to see that the behavior of the considered
metrics does not change significantly when the enabling radius is doubled.
