Currently in Location-Allocation, a demand point can only be assigned to one facility. What is your criteria for it to be served by a second facility? Are you trying to run with facility capacity and need to demand to be split? In that case you can place more than one demand point at that location and split the demand between them and then summarize later.  Jay Sandhu ... View more

I am not aware of any good free nationwide street map datasets. You can use ArcGIS online to access network analysis services such as route that uses the latest street map premium data using a pay as you go credit model. You can try this route for free with a new account that gives you some credits. Details here: Free 21-Day Trial of ArcGIS Online | Esri  and  ArcGIS Online Directions and Routing Services  You can also use these logistic services via ArcGIS Pro. That is, route on this network dataset that is hosted online by signing in with your AGOL account. Regards, Jay Sandhu ... View more

One way to solve this is to first have a set of routes that you want measure (i.e., start and end stops). Solve that route. Write out the results. Then place a barrier on the bridge and solve it again. Write out the results and compare. You can use one route layer and load in multiple start/end stop pairs based on a conman ROUTENAME property. That way you only need to solve the route layer once and get many sets of routes solved in it. Jay Sandhu ... View more

Take a look at one more place, on the Analysis tab, click on the Environments button. It will show the location of current and scratch workspace. Maybe you need to update the location of the scratch workspace. Also, I am not sure why your projects are pointing to temp location. Are you creating a new project from scratch or from a template? if it is from a template, it could have these settings in it. Jay Sandhu ... View more

In Pro, click on the left most option on the top called "Project". This will take you the backstage. Then click on the "Options" and it will bring up a popup with the current project settings. One of these will be the "Default geodatabase". Make sure this points to your project default goedatabase. Also, click on the "General" option and make sure the create project settings for Project Location and Geodatabase are set up correctly. Jay Sandhu ... View more

You can do this in four solves. Create four CF layers, e.g., CF_North, CF_South, etc. Then you can select all the incident and facility features that have the same direction, say North and then loading them into a closest facility north layer and solving. Repeat for the other directions. Export/combine the results as needed. Jay Sandhu ... View more

Tyler, VRP does two things: divide (assign) the orders between routes and then optimizes the route. This is an iterative and time consuming step. But in your case it seems you are not that concerned with partitioning the orders into routes as you have a general area you want to cover with one route. I will suggest that you use ArcGIS Pro 2.4 and the Route solver with the Find Best sequence option. It does not have a limit on the orders per route and It will solve much larger problems more quickly. For example I solved a 2000 census tracts locations in LA in about three minutes and 6000 locations in about a half hour. All 24,000 may still be too much for one solve, but you could do four solves of 6000 each. I will also suggest that you could reduce your input points by a third by just keeping the middle points and not the start and end points and use a curb approach right side of the vehicle option when loading your mid-points.

Thanks for the additional details on what you are trying to do. In your test system, do you already have the 24,000 locations divided into 24 routes and are trying to optimize each route OR you are trying to assign the locations to 24 routes optimally and then optimize? Jay Sandhu ... View more

Tyler, The VRP solver is designed for delivery scenarios where stops are spread over an area. It was not designed for arc-routing applications such as residential trash collection where every house on the block is being routed to. You can reduce the density of stops by aggregating the stops to one per edge or one per side of edge and use the VRP solver. Or you can use the Route solver to optimize one route at a time with more than a 1000 stops.  What is your use case for a single route having more than a 1000 stops? Jay Sandhu ... View more

Nothing straightforward. But, if you have an existing route that you are running, you could use the GP Buffer tool to buffer that route line and then use it select all the meter points within that buffer. Now you will have to figure out how to use this information to re-route the existing route by not visiting some roads that have all their meters covered by some other part of the route.  Jay Sandhu ...

Is it possible that the streetname field does not have valid text data? Perhaps some rows have some invalid text strings? If it cannot be explained then have Esri tech support examine the data and determine what is going on. Jay Sandhu ... View more

You can have attribute weights on junctions. These junctions could be created from your city points. But the challenge is when multiple edges coming and going out should not have the same junction weight. So the alternative is to have turn costs. You can have multiple, overlapping, edges coming in and going out of a city. For each in/out pair of edges you can digitize a turn feature (going through that junction) and assign it a cost. Hope that gives you some options to create the network that you are trying to model. Jay Sandhu ... View more

How many facilities are you solving for? Do you have a cutoff in place? If you do not have a cutoff to limit how far the facilities should look for demand, it will end up computing the entire distance matrix of 3,717 Facilities by 90,622 demand. This means a distance matrix with 367 million entries. It should work in Pro with 32 GB or RAM. But will take a while to compute and analyze. So do consider putting a meaningful distance or time cutoff to get  faster results. Jay Sandhu  ... View more

If you get an ArcGIS online account, then you can access all the network analysis functionality including the Generate Service Areas for drive time analysis without needing any additional software or data. You will have to pay some credits for using the online tools. More details here: An overview of the Network Analysis toolset—Help | ArcGIS Desktop  Regards, Jay Sandhu ... View more
