Hello Bekah. Have you verified that the dataset's values are valid and don't have non-numerical values? Would you be able to share the GTFS dataset with me? I'd be happy to debug the tool in case there's a bug, or just help you find the error in the data.

Do you need the actual number of dirty areas? Why? The NetworkDataset class has a property, isBuilt, which is set to False if the network has dirty areas and needs to be built.

Thanks for the info, @TM_NPS. You should use the Select Data utility in Model Builder to access the sublayers of a network analysis layer. You can find this utility on the Model Builder ribbon. Does this meet your needs?

That option doesn't exist in ArcGIS Pro. You can see the messages from a Solve in the Geoprocessing History pane or by clicking the launcher button on the network analysis layer's ribbon:

One further question @PamT. You said you don't want to use a network dataset template, but why wouldn't that work for you? If you don't need any complicated cost or restriction attributes, then the template will be very simple and won't require a consistent schema in the source feature classes. As long as the inputs have the same feature class names, it should just work fine. Or is enforcing the feature class names too much for your multiple organizations?

Thanks @PamT. That does make sense.
For your use case (since we're unlikely to be able to add this functionality quickly), you might be able to use Python's networkx package to construct a graph from your network dataset and then use one of the many graph search algorithms in that package to get the results you need.
Here is a sample script that creates a networkx graph from a network dataset using the nax NetworkDataset class. Not exactly what you need, but maybe enough to get you started.
Using a layer-based workflow with arcpy.na, as you suggested, is also an option.

I hear your frustration, but I'll need a bit more specific info than that. What is your typical workflow, and why do you need to know which feature dataset and set of feature classes goes with a particular NA layer? Is it because you want to preserve the output of the analysis for future use, use it as input to other tools, clean it up, etc.?

Thanks for the input, @PamT. That's an interesting use case, and I understand the problem. However, I'd still like to understand how you expect to use this workflow effectively. When you run the Create Network Dataset tool, it creates a very simple network that has only a length attribute based on the shape length of the edge sources. Is this cost attribute sufficient for your needs? I suppose there are some cases where this would be sufficient, but usually people need to adjust their cost attributes to their needs before the network is usable, so even if we gave you the ability to add travel modes, the network might still be useless.

Hello. Sorry for the delayed response.
Could you tell us why you want to control the output location and feature dataset/feature class names for network analysis layers? Your understanding of how it works is accurate, and you're right about the limitation in user control here, but we'd like to understand your workflows better so we can assess how we might better meet your needs. Thanks.

Hi Dale. It seems unlikely that we'd be able to add user-facing turn restrictions into the AGOL service dataset because it would require a schema change or some entirely new concept we don't have (turn barriers?). However, we can definitely take a look at the specific intersection that's causing you problems and work with the data vendor to get it updated. Can you send us the coordinates of the intersection and maybe a screenshot of the left turn that isn't safe?

In case this topic is still relevant to you, I wanted to share that with the ArcGIS Pro 3.4 release, you can now create a new Public Transit Data Model feature class, LVEShapes, to store the pretty on-street transit route shapes for visualization instead of just the straight-line stop connections in the LineVariantElements feature class. You can create an LVEShapes feature class from a GTFS shapes.txt file when running the GTFS To Public Transit Data Model tool.
Once you have a transit-enabled network dataset that includes LVEShapes, you can solve a Route or Closest Facility analysis and use a new downloadable prototype tool, Replace Route Geometry With LVEShapes, to post-process the output routes to swap the geometry derived from LineVariantElements with geometry derived from LVEShapes. That tool is part of the Transit Network Analysis Tools download, which you can get from GitHub or ArcGIS Online.

This topic covered a lot of ground, but one small piece of it was "My routes are being drawn as following the Line Variant Elements- is there any way to set it so that it follows the actual streets or subways that the vehicles actually take? "

I know this post is from quite a long time ago, but I wanted to report back on the functionality that was requested.
With the release of ArcGIS Pro 3.4, the Calculate Transit Service Frequency tool (the successor to BetterBusBuffers) has been enhanced to include an option to output transit statistics using actual route shapes instead of straight lines. To use this option, you have to run the GTFS To Public Transit Data Model tool in ArcGIS Pro 3.4 or higher to with the option to use your GTFS shapes.txt file to generate the new LVEShapes feature class in the public transit data model.
Instead of this:
You get this:
