Forcing network analyst to route via closest facility?

Question asked by fhilding on Jul 8, 2014


My dataset contains three parts: A) Incident location B) AED locations C) locations of available "first responders"(don't think of these like an ambulance or a fire department, but rather normal civilians)

Calculating the shortest path from C to A or C to B is doable with the Network Analyst tools, but is there a way for me to calculate two routes for each person in C?

I.e. I'd like to have both a direct route, C to A as well as the route via the AED, C -> B -> A, where B in this case is the "closest facility"(closest AED) for the individual C.

I tried to work with barriers with negative value, but that didn't help much. Any pointers on how to create the two routes?
