I am trying to understand your end goal. Simplifying your message, you have 2000 structures and N specific features within the city. You want to get the total travel time cost of starting from a structure, visiting a feature and returning back to the structure. You run Closest Facility, structures to city features. And now you also want the travel times from those structures to the N features. So if you ran a complete CF with Incident to Facility and then with Facility to Incident, you will get the same set of routes with two sets of travel times. The closest facility ranking may change. But you should be able to match up the two outputs based on the FacilityID and IncidentID fields and get a sum. This will work as long as you solved the CF with all N features and no cutoffs.

When you add the stops locations to a route, the stops feature class has information on how they are from the street feature they are snapped to. You can limit the distance a stop searches out for the nearest routeable street in tools like Add Locations. Here is screen shot from a route in ArcGIS Pro and the related field values in the Stops attribute table. Jay Sandhu ... View more

In addition to what Dan suggests, you can do a service area from that location. Make sure to turn on the lines option and do a 15 minute service area. It might show the problem (disconnected or restricted edges). You can also use the Network Identify from the NA toolbar to examine the connectivity in that area (especially after the service area) figure out the connectivity issues in your network.

I meant to say ObjectID not junctionID. Those 49 and 52 were the ones you mentioned, so I was using them in the examples. Glad that removing the 3D has given you most of the routes. The rest I expect are going to be disconnected portions of the network. Let me know if you are not able to find the root cause for them.  As far as the 3D, I just looked at the line feature class properties and realized it was Z enabled, so used the Editor to examine the 3D sketch properties and see the 3D vertices.

The streets around junction 49 are not connected to anything: I did a service area lines for 30,000 feet around junction 52 and say many disconnected areas: Purple is the reached service area lines over the blue streets. I put yellow circle around some of the disconnected edges. Jay Sandhu ... View more

Jeremy, Looking at the data explains the issue. Your street line data is 3D! So even though the X,Y may be the same, the Z values are not. For example, the three lines around bus stop feature 20 that do not connect have the following vertices: 15411, 2011544.876, 787417.068, 247.212 15521, 2011544.876, 787417.068, 247.212 5530, 2011544.876, 787417.068, 244.100 Even though the X and Y are the same, the Z values of one of them, 244.1 does not match the 247.212 of the others. Visually: You could either fix the data at the places the z's do not match or drop the z's and rebuild the network Jay Sandhu ... View more

Can you do a service area lines from a location on the blue lines and does it get stopped at the junction where it connects to purple lines? If yes, then there is some issue in the connectivity there. Perhaps the blue line is not snapped to the purple lines. Or it could be a restriction or negative attribute value that prevents the path. It is hard to "debug" without looking at the data. If the data is small (or make a subset), perhaps you can package up the data with a couple of locations that do not route and send/post it.

The screen shot in question shows the blue lines connecting to the purple lines at one location. Is the purple line split at that location if you are using End point connectivity? If it is not split, is there a vertex there for the blue lines to connect IF use Any Vertex connectivity? If you do not have it split AND you do not have a vertex on it for any vertex connectivity then you may want to run the GP tool Integrate to create those vertices. If you do use Integrate, make sure you use it on a copy of the data as it will modify the data. Integrate—Data Management toolbox | Documentation  Jay Sandhu ... View more

You can also do a service area (with the lines option, not polygons) from one of your stops and see if you can reach the second stop. It might show the connectivity problem area. Jay Sandhu ... View more

When you create a network dataset, you specify the line/road features, attribute and restrictions, connectivity policy, etc. These settings are the schema of the network dataset. You can export the schema, and use it to create another one. For example, some one sends you an updated line/road feature class. So instead of going through the property pages and re-defining all the attributes/restrictions, you can use the schema to create a new network dataset on this updated road feature class. Everything about the input data and the fields that take part in the schema must be the same.  If the data for the island and then the data for the rest of the country is in the same format then you can use the schema from the island to make a network dataset on the country. All the schema does is save you steps in re-creating a new network dataset. Do you already have the road data from all the country? It might be easier to use the Ready To Use services from ArcMap and do your drive time analysis on the street data we host via ArcGIS Online. In the Catalog view, you can expand the Ready To Use item and find the logistic services for Service Area. You will need an AGOL account and will have to use some credits to use these services.

Glad you have the travel modes figured out and using them! Jay Sandhu ... View more

The status of the Pro network dataset says Not Built. So Build the network and the service area will work. Also note that in general, the same network dataset for ArcMap can be used in Pro. You do not need to have two different geodatabases unless you have some other reasons to do so. Jay Sandhu ... View more

If you have a good connected street network, then you can construct a network dataset on it. With this network dataset, use the GP tool Make Route analysis layer with the Find Best Order option to create route analysis layer. You need to load this layer with stops or locations to visit. You can use the GP tool Feature To  Point with the inside option to create one point per input street feature. Now you can load these resulting points as stops into the Route analysis layer. Make sure to set the curb approach to No U-Turn. And solve the route layer. It should give a reasonable result for what you are looking for. If you have not use network analyst before, I suggest you run through some of the beginning tutorials.

Jamal, I tried your data and I do not see the results you are seeing. In Pro, I get the same results as in ArcMap. You could try creating a new project, re-add the data and re-create the Location-Allocation layer and solve. If you still see the different results, then click on the Share tab, and choose the left most option "Project" and then follow the instructions to package the whole project and share it back here and I can take a look at it again.

All network analyst solvers like the Route solver minimize the impedance attribute. It can be set to a time based impedance or a distance based impedance. However the Vehicle Routing Problem Solver is designed to work with a time based impedance and also uses a length attribute for certain constraints and settings. The travel mode sets up which of the impedance attributes should be used. And if your network dataset has more than one impedance attribute and some are time and some are distance, it sets up which one to use for time and which one to use for distance if needed beyond the impedance attribute. For example, see the travel modes for the tutorial Paris network dataset which has driving and pedestrian travel modes. In your screen shot, the impedance is set to Time Cost. This is what is used to solve the route. Below the impedance attribute, the property page shows what was set up as the time based attribute, in this case Travel Cost and it is grayed out meaning that is what has been set for impedance for this travel mode. Below that is the distance based attribute, Length in this case. The distance based attribute is not being used by the Route solver. Only the VRP solver could use it if certain constraints were set up. So, in summary, the Impedance attribute is used to solve the network analysis.   Jay Sandhu ... View more
