<span>I am carrying out a viability analysis in which, starting from a series of points (contained in a layer) and from the city's infrastructure network, I want to draw the isochrones to understand the distance that can be reached in 5 minutes from those points. </span></div>

<span>Then I want to hypothesize the interruption (and/or slowdown) of some road sections to see how the isochrons change.</span></div>
