The issue is not if the facilities are properly located, but what areas can be reached from them in the specified cutoff with the current travel settings.  Can you share you facilities/demand here for further testing? Or you can contact Esri technical support and share your location-allocation layer so that they can replicate the problem. Regards, Jay Sandhu ... View more

As the message says that there are no facilities within the cutoff of the demand locations, means some travel setting like a restriction or connectivity issue is preventing finding paths on your network dataset. Since it cannot find a path it cannot find any more facilities to locate.  I would suggest that you create a service area layer, load your facilities into it and do a two or three minute service area and see which facilities are not able to generate the requested service area. You may want to turn on the lines and polygons option for the service area to see the problem area. Jay Sandhu   ... View more

Can you describe the settings you are using? For example, what type of Location-Allocation model are you using, cutoff, impedance attribute? How many facilities are you trying to find? Jay Sandhu ... View more

Are you looking to generate N by M OD matrices? Or are you looking to generate paths between pairs of points? For pairs of points, the workflow is to use the Route solver with the ROUTENAME property. Jay Sandhu ... View more

You have to first verify that your network dataset has been setup and built correctly. One way you can do that is to use Service Area solver. Place one facility somewhere and set the option to generate Lines and not polygons. Set a large break value and solve. In the output, are all lines being returned? Does it show any disconnected places. The other thing you can do is to use the Explore Network tool to check the connectivity and the impedance values to make sure they are correct.

To get an updated ETA, you can solve a two point OD to get the travel time left to reach the destination. You can also send a request to our logistic service to get that. Some more description of that is here: What’s New in ArcGIS Routing Services (esri.com) Jay Sandhu ... View more

I am glad you were able to resolve it. Jay Sandhu ... View more

Can you provide some information on your network dataset? How many edges/junctions does it have? Does it have a Hierarchy and is that used during the solve? How long does a two point route take to solve on that network? Perhaps there is something about the network dataset that is causing slow solves.  Jay Sandhu ... View more

Network Analyst is quite well supported in ArcGIS Pro! When using the arcpy.na make analysis layer tool, the layer is created referencing the analysis workspace in a file geodatabase.  in_memory or memory env is not supported. If you are automating NA workflows in python then the recommended way is to use the arcpy.nax module (not layers). These python analysis classes will use in_memory feature classes (not file geodatases) and are high performance.

The route solver does not close a loop. If you want to return to start location then you have to add it as the last stop with Preserve First and Last stop option. For the unreachable streets, there maybe some restriction (gated community or limited access road) that is blocking the visit to that neighborhood. Jay Sandhu   ... View more

Can you provide any more information on how you are solving this? Is it using the ArcGIS Online routing service or using your own local data? Generally a message like this means there is no path to the location which could be because the underlying network data may have some connectivity problem. Jay Sandhu ... View more

With your own centerlines, you can use the Feature To Point tool with the Inside option to create mid points. Feature To Point (Data Management)—ArcGIS Pro | Documentation Jay Sandhu ... View more

Generally I recommend to generate mid points on every edge NOT intersections. And also set a curb approach right property and you can set u-turns at dead ends only.  That way streets are travelled to the end. That said, covering every street efficiently requires a different approach then using the TSP solver that ArcGIS provides but you may get good results.  Also are you using local street network data or online service? There are limits on the stops you can pass to the online service not for local data, but there are practical limits on how much you can optimize in one solve. BTW, what is your use case for travelling every road in the city? Jay Sandhu  ... View more
