In your model you have the Add Locations tool two times. I am hoping that once it is to load Facilities and the second to load Incidents. Make sure that when you are loading the incidents, the sub-layer in the Add Locations tool is actually set to Incidents. By default it is set to facilities. So you may be loading both sets of locations as facilities and no incidents are loaded. You can double-click on the add locations box and then check the sub layer parameter and set to Incidents where needed. Jay Sandhu ... View more

Your question is not very clear on what you are trying to achieve. When you create/build a network dataset, "nodes" are generated and their location is written to a feature class in the feature dataset where the network dataset exists. You can use these nodes in anyway you like for loading into analysis layers as locations (stops/facilities/etc.). Jay Sandhu ... View more

If you want to learn how to set up data and create network dataset, I will suggest that you go through the Network Analyst tutorials for that. They have sample data that you can examine on how to set up feature attributes and then map them to network dataset attributes. See link below: Exercise 1: Creating a network dataset—Help | ArcGIS Desktop  and Exercise 2: Creating a multimodal network dataset—Help | ArcGIS Desktop  Jay Sandhu ... View more

If I understand your question correctly then you should be able to use the Closest Facility Solver from Network Analyst. The one origin that you have should be loaded as the Facility in the CF layer and then all the other community locations should be loaded as Incidents. Now solve for that 1 closest facility and you have will get paths from each incident to that one facility. Jay Sandhu ... View more

The OD in transportation planning has different meaning that the OD solver in Network Analyst. There is no straight forward way to sum trips per OD pair on the links of a network. But it can be done. To do what you want to do, use the Closest Facility solver. Load your origins A and B as Incidents and load your three destinations as Facilities. Set the CF to solve for three closest facilities and solve the layer. Once the solve is done, Run the GP tool Copy Traversed Source Features with the CF layer as the input network analysis layer. This will now create a new line feature class containing the individual line features for all the paths traversed. Now you will need to do some work to assign the number of trips to each route (OD pair) and then sum up the values per edge. Jay Sandhu ... View more

Now that I can see the actual error messages, it is saying that your locations are falling on edges that cannot be reached, most likely because they are restricted. So you need to see check the settings of your network why those edges are restricted. Besides that, you can move the stops to non-restricted edges. You can do this by: 1. Open the route analysis layer property page. 2. Click on the Network Locations tab and then at the bottom left, check on the "Exclude restricted portions of the network" as follows: 3. Click Apply 4. Then in the NA Window, right-click on the Stops and choose Recalculated Location Fields and pick ALL (as shown below) This will "move" the stops to other close by edges that are not restricted and solve the route again. In the MODEL, you can check on this property in the ADD LOCATIONS tool as follows: Hopefully now the route will solve. Jay Sandhu ... View more

I am trying to help you. You need to show the error that you are getting in the model. The screen shot you included says: failure. No Solution found. Failed to execute. WHAT does it say above the "failure"? Also, are you able to use the NA toolbar to click two stops on the Dherarun data and solve for a path? Does that work? IF it does not solve a path through the NA toolbar then the mode will not work either. Can you show a screen shot where we can see what locations you are passing in to the model? Jay Sandhu ...

If you are using AGOL to compute drive time polygons then you have to use credits. There is no free service. Jay Sandhu ... View more

Your screen shot does not show the entire error message. And it is not clear what your model is doing. So it is not possible to say what is going on. There are many reasons a route may not find a path. For example the network dataset is not built or fully connected. There could be restrictions that cause no path to be found. The locations may not have snapped to the network due to search tolerances, etc. Are you able to solve a route through the UI without using the model? Jay Sandhu ... View more

"Offline" would mean that you would need to have your own local street network dataset that is configured with a traffic feed that you have purchased from a vendor. So yes, it is possible to do this but if you do not have your network data and traffic feed it will be much more expensive. Jay Sandhu ... View more

What kind of problem are you running into? Jay Sandhu ... View more

Not sure if I understand your issue or the attached picture. The search tolerance is for locating the input facilities. It puts a limit on how far to search the network for locating. That tolerance does not have anything to do with the subsequent service area solve which will travel on the network to a specified break distance or cost. Jay Sandhu ... View more

Use the Closest Facility Solver. Load your locations as facilities and incidents and then make sure to set the number of facilities to find as 234. When you solve, you will get 234 by 234 routes with the geometry output as you expect from the route solver. The OD Cost Matrix is a similar tool but runs quickly as it does not spend the extra time writing out the detailed route geometry, and it is useful when you only need the shortest path costs.
