Hello Alex.  This is a very strange error.  The error message tells me that it actually failed when trying to run the Add Field geoprocessing tool.  I don't know why that tool would generate a UnicodeEncodeError while trying to add a field called "stop_id". What is the name of your output stops feature class?  Does that path have any non-ascii characters in it?  If so, perhaps try again using a path with only standard ascii characters and see if that fixes it. Another thing to try is creating a feature class with the same name and path as the one you designated with the tool (or using the one the tool created) and manually running the Add Field geoprocessing tool.  Try to add a text field called "stop_id".  If the tool gives you the same error, this is sufficient for you to call Esri Support, and they can diagnose and resolve the issue for you. ...

If I understand your question correctly, you want to sum the total area reached at all different times of day.  If you run the Prepare Time Lapse Polygons tool, you could just run the Dissolve tool on the resulting polygons to dissolve them all into one polygon, and then calculate the area. ...

Hello Claudia.  It's a little hard to tell from your description exactly what the problem is.  I was going to try to download your data and take a look, but it's downloading so slowly that it will be the weekend before it finishes. If you haven't already please make sure to read the User's Guide for the tools you're trying to use. One thought I have is that maybe there's a problem with the day or date you're using.  Some GTFS feeds use the calendar.txt file to define a regular schedule that repeats on specific weekdays.  However, some other GTFS feeds do not model regular service and instead choose to model all (or most) of their service as "exceptions" using the calendar_dates.txt file.  Possibly some/all of your data does this, so if you use a generic weekday in the tool input, it won't pick up most of the service.  Try instead using a specific date in the tool input.  Make sure to use a date that falls within the valid date range of the feed, which you can determine by looking in the calendar_dates.txt and calendar.txt files. When you say you run the other tools but don't get an output, what do you mean?  It didn't appear in the map?  Did you check the output location you specified in the tool parameters?  Perhaps it didn't automatically add to the map for some reason, but you can manually add it from the saved output on disk. If you're still having problems, the best thing you can do is to describe your steps and the outcome with as much detail as possible, maybe even include some screenshots.  For example, what inputs have you specified for the tool parameters?  When you ran the tool, did it produce an error?  If so, what is the exact error message text?  If you're unhappy with the results, what exactly does the output look like, and why does this seem wrong?  With all that information, we'll have a much better chance of being able to help you.  ...

I don't completely understand your question.  However, this section of the user's guide explains how to create a time-lapse polygon video with your transit network. ... View more

A couple of things here related to 64-bit background geoprocessing: 1. If you have the 64-bit background geoprocessing extension installed, you should have two versions of python.  One is a 32-bit python associated with ArcMap,and the other is a 64-bit python associated with the 64-bit background GP extension.  You should keep both of these on your computer.  Do not delete either one, as the product they're associated with will stop working correctly. 2. Since you have two versions of python on your machine, you need to be careful about which one is being used and when.  If you're running a standalone python script, you need to point to the correct python executable for the version of python you intend to use.  If you want to run against ArcMap, use C:\python27\ArcGIS10.6\python.exe.  If you want to run against the 64-bit background GP extension, use C:\python27\ArcGISx6410.6\python.exe.  You will need to use these explicit paths in the command line or configure your python IDE to use whichever of these you want to use.  I'm assuming you want 64-bit since you went to the trouble to install it.  It will be better for solving large problems because it can use all your memory resources. 3. If you're running tools in ArcMap, they will use ArcMap if you have background geoprocessing turned off.  If, instead, you turn background geoprocessing on (Geoprocessing menu -> Options -> Enable background processing checkbox), it will switch over to using the 64-bit background geoprocessing extension. 4. If you want to use the Add GTFS to a Network Dataset tools and the network datasets produced with them with the 64-bit background geoprocessing extension, you have to do an additional installation procedure, as described in the user's guide.  However, the error you're seeing looks unrelated to this. --- I think your current issue is unrelated to 64-bit background geoprocessing, though.  I see that you have a very large list of input GTFS datasets.  Can you try adding just one of them to the tool dialog?  Do you get the issue if you just have one in there?  If not, can you add them in one at a time until the error appears?  Maybe it's something about a specific dataset, and if that's the case, maybe you can send me that dataset for debugging? ...

Wow, that's a really unhelpful error message.  Sorry about that!  I really don't know what would cause that problem, so I think you're right that uninstalling and reinstalling Add GTFS is a good thing to try. The transit evaluator is not saved in the network dataset itself.  It's part of the overall tool installation.  Without the tool installed, your network datasets will not work.  However, if you reinstall the evaluator, they should start working again.  They are not going to be permanently broken. The only exception to this would be if your networks were really really old and I had made some changes to the evaluator itself in a way that was no longer compatible with older networks.  I do that sometimes, since this tool is effectively in permanent beta and not guaranteed to always be backwards compatible.  However, I haven't done anything like that in like 3 years or more, so I don't expect any problems with your networks if you were to uninstall and reinstall the latest version. Let me know if uninstalling and reinstalling doesn't fix the problem. ... View more

Not necessarily.  First try adjusting your connectivity policy according to the provided documentation.  If that doesn't work, you might need to make some edits to the data. You can use the Integrate tool with an XY Tolerance of 0 to add vertices wherever streets cross, or use the Planarize editing operation. ... View more

Did updating the tool work, or are you still having the problem? ... View more

As explained previously, use the RouteName field in the Stops sublayer in Route to control which route stops are along the same route.  The order in the table controls the order the stops are visited by the route. Example Stops table: OID Name RouteName 1 Case 1 Case 1 - Facility 1 2 Facility 1 Case 1 - Facility 1 3 Case 2 Case 2 - Facility 1 4 Facility 1 Case 2 - Facility 1 5 Case 3 Case 3 - Facility 12 6 Facility 12 Case 3 - Facility 12 Example resulting Routes table: OID Name Total_TravelTime 1 Case 1 - Facility 1 25.5 2 Case 2 - Facility 1 43.2 3 Case 3 - Facility 12 12.6 ...

You need two Stops for each case-facility pair, one for the case, and one for the facility.  So, yes you will have many copies of the facilities in your input Stops, but you do not need 1000 copies of each.  Each case went to one facility, so you will have 2000 total stops: 1000 for each case, and 1000 facilities, which will be multiple copies of the original 14, one copy per case. ...
