"Create a service area where the sum of the lengths of the edges traveled equals one" is precisely what I am interested in resolving with two clarifications. Obviously, "one" should be a variable, and almost equally obvious is that all edges be of equal length. I believe that these two restrictions should produce one unique solution.  One (possible) problem that I anticipate is in the case where two routes (of different lengths) converge on the same edge, because I'm not certain which length is used for the calculation. Your thoughts? The purpose of this calculation is to determine the "best" location for future fire stations.  Other variables withstanding, a station would service a given length of road miles, and be centrally located. This is not a critical calculation, but more one of an intellectual interest, so please don't feel obliged to pursue this solution if it becomes too time-consuming. ... View more

Joe, I was more hoping for an already packaged tool, though... ... View more

Joe, I have an iterative process which may work, ( I haven't tried it yet) but it would be rather time consuming.  One could create several service area "rings", and determine which two span the desired "route sum". With finer and finer ring increments, one could then determine the optimal ring. (within a given tolerance) Done in a script, it accelerate the process considerably. I regret I don't have these programming skills, though. ... View more

Thanks Dan, But I think this does not answer my question, The following is a post from Joe in which I try to better explain my request:\ Let me try to clarify.  I want to know what unique distance one would need to travel (along all possible routes) to create a service area containing a routes whose sum of is equal to a set number. In this case, the route distance is what I am seeking. What is known is the maximum number of mile the service are may contain, and the location from which to start. Does this help? ... View more
