Answering question 1: There is no drop-down menu to select the directions language. You can select the language in the Directions geoprocessing tool, or you can set the directions language for a Vehicle Routing Problem layer using the following code in the python window: # Get the current ArcGIS Pro project proj = arcpy.mp.ArcGISProject("current") # Get the current map mapObj = proj.listMaps()[0] # Find the Vehicle Routing Problem layer in the map # You might need to change the layer name string below if your layer's name is different. vrpLayerObj = mapObj.listLayers("Vehicle Routing Problem")[0] # Get the layer's solver properties solverProps = arcpy.na.GetSolverProperties(vrpLayerObj) # Set the directions language to Portugal Portuguese solverProps.streetDirectionsProperties.language = "pt-PT"‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ You do not need to install a language pack to get directions in Portuguese.  All directions languages are available all the time, even without language packs. (This is new - ArcMap and older versions of ArcGIS Pro required a language pack installation to get directions in non-English languages.) Answering question 2 We did not change the Solve Vehicle Routing Problem tool between ArcGIS Pro 2.5 and 2.6.  Can you further explain your question? Answering question 3 I am going to ask a colleague to help you with this question. ... View more

There is no ribbon or Directions pane setting for directions language at this time.  However, you can run the Directions geoprocessing tool and select the desired language in that tool. If that doesn't give you what you want, there is a way to set the VRP layer's directions language via python.  Let me know if you want to learn about it. ... View more

Spikes like that are a common artifact of the polygon generation algorithm in ArcMap.  We have implemented a new and improved polygon generation algorithm that makes the Service Area polygons look more bubbly or cloudy and less spikey.  You can access the new algorithm in one of two ways: 1) In ArcMap, open the properties of your network dataset. On the Optimizations tab, turn on the box for the Service Area Index.  You might need to re-build your network dataset after this, but I can't remember.  Future Service Areas using this network should use the newer algorithm. 2) Use ArcGIS Pro instead of ArcMap.  ArcGIS Pro Service Areas always use the new algorithm. ...

It needs to be a list of the string names of the attributes you want to accumulate. route.accumulateAttributeNames = ["VehicleTrack", "VehicleWheel"] ... View more

I'm still not entirely sure what your workflow is, but if you're using saveAsLayerFile() and then adding the saved .lyr file to the map and looking at the travel mode, it's possible the travel mode name displayed will be incorrect or inconsistent. That's because .lyr files are the old ArcMap layers that do not have a concept of travel mode.  I believe the settings should be consistent, but the name might be off.  I'm not really sure. This is why I suggest that you use the older MakeLayer, Add Locations, Solve workflow n your script. The nax solver objects just really aren't designed to work with layers. ... View more

The brackets are added automatically to the name.  You don't need to do anything with those. # Get all existing travel modes from the network dataset travel_modes = arcpy.nax.GetTravelModes(network) # Get the existing "Driving Time" travel mode to use as a template existing_tm = travel_modes["Driving Time"] # Construct a new TravelMode object from the existing travel mode new_travel_mode = arcpy.nax.TravelMode(existing_tm) # Update the new travel mode's impedance new_travel_mode.impedance = "MyImpedance" # Use the new travel mode object when constructing a OD Cost Matrix object arcpy.nax.OriginDestinationCostMatrix(network) od_object.travelMode = new_travel_mode‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ ...

Just set the accumulateAttributeNames property of the Route object, the same way you would set the travel mode.  The complete list of properties can be found here: Route—ArcGIS Pro | Documentation  ... View more

I can't really follow your workflow from your description, but I suggest you follow the last code sample on this page: TravelMode—ArcGIS Pro | Documentation  Rather than editing the travel mode retrieved from the network directly, try instantiating an entirely new travel mode using the network's travel mode as a template.  Then change the impedance for the new travel mode and see if that works. ...

No, the accumulate attributes are independent from the travel mode. ... View more

I'm guessing from your questions that you are writing a python script tool that you intend to run as a geoprocessing tool within ArcGIS Pro.  Is this correct? If this is the case, then the proper way to add the output network analysis layer to the map is not to use the mapping module to add it explicitly but to simply add an output parameter to the script tool.  Let me explain further. First, when setting up your tool parameters in the tool dialog, create an output parameter.  Set the type to Network Analysis Layer.  Make a note of the index for this parameter.  You can also set up a symbology layer for this parameter.  By specifying a symbology layer here, it will automatically apply this layer's symbology to the derived output when it adds it to the map. When you run the tool, it should automatically add the layer to the map. If you don't want the users of your tool to specify the path to the output .lyr file, but instead you want to handle that internally, you can make the parameter definition of type "Derived".  In the script, once you have your output layer path, assign the layer to that parameter using arcpy.SetParameter(). Note: if your ultimate goal is to create fully-functioning network analysis layers as the output of your tool, the arcpy.nax module might not be the right choice.  It might be better to use the classic Make Route Analysis Layer, Add Locations, Solve workflow.  The saveAsLayerFile() method for the nax solver objects is primarily meant for debugging. ...

Yeah, the layer itself exists only in the map, but its data is sitting in the geodatabase grouped into a feature dataset.  You can save the layer as a layer file using the Save To Layer File tool if you want to re-use it later, but you have to be careful to keep the analysis database and the network dataset with the same relative paths to the .lyrx file or else it will be broken. You can also save the layer as a layer package.  Both the analysis data (the stuff from the feature dataset) and the network dataset will be packaged into the layer package.  This guarantees that you'll have everything, but you risk proliferating copies of your network dataset.  That's not good if your network is large. ...
