Hello eveyone.

My question is  kind of simple. I have been using some of the tool such as Better Bus Buffer. I have a GTFS of Mexico City which  contains around 6,000 stops and 100 lines.  My doubt is about the time  that takes the frist step  (preprocess buffer). 

I understand that Arcmap does not give you a procees bar (that gives the percetage of the process achived) like Qgis. and of course the amount of time depends in my hardware and the size of the data that I am analyzing but  the procees has been computing like 15 hours and still  doest produce the second outpus which is Step1_FlatPolys.

Thank you everyone

The Step 1 – Preprocess Buffers tool (BetterBusBuffers Count Trips in Polygon Buffers around Stops) does a lot of complicated geometry operations.  If your transit agency is huge (doesn't sound like it's that huge...) or if your buffer size is very large, it may take a really long time to perform these calculations.  Also, if you're using a shapefile network dataset, it might be slower than a file geodatabase network dataset.  If your network dataset's source feature classes don't have a spatial index for some reason, this will make things extremely slow.

You might also just be running out of memory in ArcMap.  ArcMap is an older 32-bit application that cannot make use of the full memory resources of your computer.  Try running this tool in ArcGIS Pro, which can handle larger problems much more easily.
