Here's a suggestion from a colleague: Do it in two passes:   Pass 1: Spatial Validation – spatial join from “Pickup” points to the “Bus Route” polygons Each pickup point (in JoinLayer) now knows which bus route it is within A point not within any active bus route area (ie: null joined-field values) is non-compliant   Pass 2: Temporal Validation – select by attributes to check if the date range is OK Find the good ones (it’s easier SQL to write) Select from JoinLayer where [PICKUP_TIME] >= [ROUTE_START_TIME] AND [PICKUP_TIME] <= [ROUTE_END_TIME] Invert the selection -> the pickup point is outside its joined bus-route time   ONE BIG LIMITATION though: Not guaranteed to work with points inside multiple (overlapping) bus route polygons The joined bus route time-frame may not comply, but another one might Spatial join only gives you one result… Suggestion: Run the above For the ‘failures’, identify pickup points that are in multiple bus routes Mark these as “maybe’s” Handle them some other way (if only a few, maybe manually?) ...

My guess is that one of your source feature classes is not a normal point or line feature class.  Maybe it's a multipoint or a raster or some other weird thing. ... View more

Yes, you can use the template you created to make new network datasets in other geodatabases.  Set the output_feature_dataset parameter to the feature dataset in the geodatabase where you want to create the network. ... View more

Hello Jesse.  This is not the first question I've seen where someone was trying to determine whether paratransit pick-ups and drop-offs fall within the service hours of a bus line.  Is this something that people commonly need to do as part of ADA requirements?  I know that the federal mandate places the paratransit service area within 3/4 of a mile of fixed-route bus lines, and I'm considering making a tool that will calculate this automatically, but I was unaware of a time of day requirement.  Can you point me toward some official documentation explaining that requirement, or otherwise further explain why you need to do this? Regarding your question: ArcGIS 10.1 isn't supported by Esri anymore, as the product has been retired in favor of newer versions.  Here is some documentation about how to use the time slider to filter time-enabled data: Using the Time Slider window—Help | ArcGIS Desktop I don't know whether that was available as far back as 10.1, though. Here is similar information for ArcGIS Pro: Set the time properties on data—ArcGIS Pro | ArcGIS Desktop  ... View more

If you want to create a network dataset automatically with specific settings, the best thing to do is to create it once manually (currently only possible in ArcMap) and create a template from it.  Then, in the future, you can re-create a network with identical settings, with the same data or different data, using the Create Network Dataset From Template tool. ...

You said you used the "use network location fields" option.  I wonder if this is the problem.  Network location fields are values stored in fields in the data indicating where along the network each point should be considered located.  Points are almost always offset a little from the network, so usually we use the closest non-restricted network position and consider that as the start point for the analysis.  You can store these network locations in fields and re-use them in the future to speed up your analysis (because the network locations don't have to be re-calculated).  However, if you have edited your network or you're using a different network, these network locations get become outdated or incorrect.  I recommend running Add Locations again but this time using geometry to calculate fresh network locations.  Try running the analysis again and see if it works this time. Also, your OD and CF might have succeeded, but you might have gotten warning messages indicating that some points were unlocated and ignored. The warnings don't pop up automatically when you hit the Run button in the ribbon, but you can see them if you hit the little square launcher button in the bottom right corner of the section of the ribbon where the Run button is. If using geometry doesn't solve the problem, then you need to investigate the specific feature that failed to locate and make sure it's really in the right place. ... View more

What version of ArcGIS are you using?  And is your GTFS dataset available somewhere where I can play with it and run some tests? ... View more

Glad that's working.  Keep an eye on it to make sure it doesn't slow down over time.  If it does, then it probably has to do with the truncation and re-population of those tables. ... View more

You'd have to use the regular Delete tool, not DeleteFeatures.  That's the short answer to your question. The longer answer is that your automated process (script or model) should probably be doing this: - Create a new file geodatabase - Create a new feature dataset in that file geodatabase - Copy the new street data into that feature dataset - Run Create Network Dataset From Template using that feature dataset - Build the new network You don't need to delete any old networks to make this work.   You can create an entirely new network from a template as long as the schema of the input data matches the schema used when creating the network dataset.  So, if you had data from multiple municipalities that all use the same data model, you can create a separate network for each one using the same template. ...
