How do I override the network analyst barrier limit?

Question

I am running network analyst and encountered the following error:

ERROR 030095: The number of street features affected by PolylineBarriers limit of 500 has been exceeded.

I interpret the error to mean that my dataset of nearly 2000 barriers is too large. It would be problematic to decrease the number of barriers so I am hoping the limit can be overridden. I am not certain what language is appropriate for the override function or whether that is indeed the issue.

This error message indicates to me that you are using a service, probably the ArcGIS Online service based on your later comments, to solve your network analysis problem.  The ArcGIS Online services do indeed have limits in place for the number of inputs.  There is no way to exceed these limits while using this service.

If using a large number of barriers is essential to your workflow, you will need to use your own network dataset instead of the ArcGIS Online service.  You could create your own network dataset if you have street centerlines for your area of interest.  Here is a a tutorial showing you how to do that: Create a network dataset—ArcGIS Pro | Documentation   However, creating a high-quality network dataset is a difficult procedure, particularly if you aren't starting with high-quality data.  A better option might be purchasing Streetmap Premium for your area of interest.  This includes a ready-to-use network dataset that contains the same data used by the ArcGIS Online Services, but since you have the data yourself, there are no service limits.

Well, I honestly have no idea. I have been using the default network because I haven't yet developed the skills for building and editing networks. I may be in over my head on this one, but I'll keep looking into it. Thanks for the suggestion!

Could you sort-of cheat and cut the network edges at the barriers?
