Comparing and summing isochrones

[wacekk]

As I wrote in another issue, I am looking for a method for comparing isochrones generated using spNetwork (e.g. comparing two design variants). The road network in both cases will not necessarily be identical, it may differ, for example, by a built-up road. However, I assume that the vast majority will be identical (which allows individual sections to be assigned the same ID).

I am also interested in summing up - calculating the total travel time, e.g. to school and back, taking into account one-way streets. I am able to generate a network "to" and "from" by artificially changing the direction of one-way roads.

Of course, other operations than calculating the minimum, maximum (calculating the maximum distance traveled in the morning or afternoon) or summing (analyzing the path to and from a point) and subtracting (comparing variants) do not make sense on isochrones.
