You should use the Reorder Stops To Find Optimal Route option. By default, a route traverses stops in the order you define. However, you can possibly shorten the route further by letting Network Analyst find the best order. It will account for a variety of variables, such as time windows. Another option is to preserve the origin and destination ...
The ArcGIS 10.2 and 10.2.1 Online Help on Service Area Analysis does not seem to provide any information on how Aervice Areas are calculated. It is possible/likely that proprietary algorithms, which may be of commercial value to Esri, are involved. Consequently, I think your best chance to find out will be to submit a question to your local Esri Support to ...
Use tool: Feature Vertices to Point.
I think that, there are some gaps. Try to create new Topology with rule "must have not dangles" for your network and validate it.
ArcGIS Network Analyst provides you with a way to specify the point layer that will be used as a landmark layer (go to the "Landmarks tab" section). The point features from this layer will be used when generating the directions of the Route layer. This will let you introduce more specific route guidance with statements like "Turn right at Alan's Hardware ...
If I understand your question, you want the name of the algorithm that is used by ArcGIS. From what I know, it is primarily based on the Dijkstra algorithm. Here is the pseudo-code from Wikipedia : function Dijkstra(Graph, source): 2 for each vertex v in Graph: // Initializations 3 dist[v] := infinity ; ...
use weights with Make Closest Facility Layer (Network Analyst) Makes a closest facility network analysis layer and sets its analysis properties. A closest facility analysis layer is useful in determining the closest facility or facilities to an incident based on a specified network cost.
I know little enough about statistics, but I'll take a stab at this because it sounds familiar. 'Best' is another story. I'm also a little unclear on exactly what you're trying to achieve. Broad overview, so you have run your closest facility and generated a table with drive times. Next you would need to classify your populations (which happen to also be ...
