Your network configuration looks correct.  The null attribute parameters are also correct.  You can read about the supported parameters for the Public Transit evaluator here: https://pro.arcgis.com/en/pro-app/latest/help/analysis/networks/public-transit-evaluator.htm#ESRI_SECTION1_9FF9489173C741DD95472F21B5AD8374 My guess is you still have some connectivity problem.  Try using the Explore Network tool to click on one of the LineVariantElements features.  The map will show which other network features are connected to it.  Check to see whether the StopConnectors are correctly connected.  Also click on a StopConnectors feature and make sure it connects to the street. If that still doesn't work, either contact Support or post your data here and I can take a look.  (You can also send me a private message if you want to share the data privately, but be sure to leave a comment here since Esri Community's private message system doesn't give me an e-mail notification.) ...

The next thing to check is that your network analysis is using a day of week or date and a time of day.  If you don't use a time, the analysis will never use the transit lines.  Make sure you're using a date and time when transit service is available.  Some specific details on that are in the tutorial's final section: https://pro.arcgis.com/en/pro-app/latest/help/analysis/networks/create-and-use-a-network-dataset-with-public-transit-data.htm#ESRI_SECTION1_0547477F1C834EEAB22B368F6F4AB5B9 If that isn't the issue, the next thing I would check is that the impedance attribute and travel mode are configured correctly and that you're using the right travel mode when solving your layer. ...

The Time Cost and Distance Cost travel mode properties are primarily used by the Vehicle Routing Problem solver.  Some other solvers include them as an accumulated attribute by default, but in general they don't really do much. ... View more

A couple of other questions: I can't see from your code snippet where you save the resulting Service Area polygons.  Are you using the export() method?  This might be a dumb question, but are you sure you're saving the result of each iteration to a separate feature class and looking at the right one in the map?  What happens if you run the script with just one travel mode (the one for bus that you're having trouble with)? Are you sure the points you're using as inputs are locating in the desired place on the network?  Are you using some network location settings in Pro that you're not using in your script? Are you sure it's really working as intended within the Pro UI?  Can you paste a screenshot of your layer's analysis settings and your network dataset configuration (connectivity policies, travel mode and attribute configuration)? ...

It looks to me like this code should work.  However, I can't see where you created the Service Area object (that's probably not the issue).  What results are you seeing that tell you the travel mode isn't working correctly?  Can you give some more details or post some screenshots? ... View more

Make sure the streets have a vertex at the location where the bus stop intersects them.  Without the vertex, the Override connectivity policy won't work. By the way, we have a formal recommended way to create a network dataset that supports public transit routing, which is described in this tutorial: https://pro.arcgis.com/en/pro-app/latest/help/analysis/networks/create-and-use-a-network-dataset-with-public-transit-data.htm ...

I still can't reproduce the problem using the data and script you sent me via private message.  I responded to your private message with more details and further suggestions, so please have a look. ... View more

Thanks.  For the network, I was mostly interested to understand whether it was a mobile gdb or a licensed, compressed fgdb (sounds like it is not) since those can have different behavior in some circumstances. One further question (sorry!): How are you running this script when you experience the slowdown?  Are you running it in standalone Python, in Pro via a custom script tool or python toolbox tool, in a notebook, or some other way?  I wonder if the problem only occurs when run in a certain way, indicating an issue with memory clean-up in whatever the running mechanism is. ...

So far not reproducible for me.  Could you please tell me the following information: What version of ArcGIS Pro are you using? What type of network dataset are you using?  (file geodatabase, mobile geodatabase/MMPK, Streetmap Premium (what type and vintage), etc.) ... View more

Okay, I'll give it a try on my end. ... View more

Okay, sorry to hear it wasn't that simple. Before I spend a ton of time running your code, have you tried running it without creating those output spatial dataframes at all?  Because dataframes are stored in memory, my suspicion is that the problem is something to do with that.  If removing that piece eliminates the problem, we can exclude Network Analyst as the culprit and focus on the spatial dataframes to see why they are eating/leaking memory. ...

Thanks for the information @wayfaringrob.  Sorry, one further clarification question to make sure we understand the problem completely:  When you say "scaling", does your student have their Windows display setting set to something above 100%? Or if not, could you explain in more detail what you mean by "scaling" so we can attempt to reproduce the student's exact situation?  Thanks. ... View more

I just tried to reproduce the progressive slowdown using tutorial data and a very simplified workflow, and the slowdown didn't happen.  So, let's try to dig into your more complex workflow a little deeper. First thought: Is it possible that your machine is progressively running out of memory as you store more and more stuff in that results dictionary?  I don't know how large your store_assignments_df spatial dataframe is with each iteration, but if it's really big, maybe your machine is just using more and more memory.  If you run your code but don't return and store the results, does it still progressively slow down? If that doesn't help, would it be possible for you to share your data and full tool code with me along with specific instructions on how to run it?  We can definitely try to debug the problem on our end, but since my attempt at a simplified script didn't reproduce the problem, I think we'd need to have all your stuff.  If you don't want to share it publicly, you can send me a private message through Esri Community (and please leave a comment here letting me know you did so, since the Esri Community platform doesn't send notifications when you get a private message). ...

If the main thing causing you a problem here is the labeling and symbology, you might be able to resolve the problem by saving a layer file with the symbology you want and calling the Apply Symbology From Layer tool to apply this symbology to the .lyr files saved by your tool. ... View more
