TimeTable #FATAL ERROR: Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory

[471Q]

Hello, I have created the timetable.txt and timetable_stop_order.txt files and generated the HTML, I have total of 8700+ .html files to be generated, I think I messed up with the additional file. The .html file generated for timetable seems to be repeated multiple time for the same route and all of the 4000+ files are mon-fri only. after generating 4100 the cmd stopped working with the FATAL Error.

Any help is highly appreciated.

Thank you.

Be sure the file is named timetables.txt. Try first with only one timetable in timetables.txt to see if it generates things correctly.

Once you know it is using your timetables.txt file and generating correct timetables, if you need to allocate more memory, you can do so using https://gtfstohtml.com/docs/processing-large-gtfs

Also be sure to use the latest version of node.js 12.18.4

Actually I think the way I made the timetable.txt file is wrong. I just tried only the timetable.txt still it starts generating an 8780 timetable file. Following the documentation, I used python to join different .txt files with trip_id, route_id etc. In the documentation you did not mention any need for joining anything. But I am confused If I'm not joining different table with the foreign keys then how should I create the timetable.txt file

P.S: if I don't use any additional file only 232 timetable .html files are created

Be sure your file is named timetables.txt not timetable.txt (note the s). Can you share your GTFS and your additional timetables.txt and timetable_stop_order.txt files with me?

here is the whole folder, including the two additional files. gtfs.zip

just in case you want to see how I created the additional file, here is the python notebook

In your timetables.txt file I see many duplicate rows. Each row should be a unique route_id/direction_id/day-of-week combination - no need to duplicate.

For instance, the first 15 rows are identical:

0,13095,0,20200629,20201129,1,1,1,1,1,0,0,2 1,13095,0,20200629,20201129,1,1,1,1,1,0,0,2 2,13095,0,20200629,20201129,1,1,1,1,1,0,0,2 3,13095,0,20200629,20201129,1,1,1,1,1,0,0,2 4,13095,0,20200629,20201129,1,1,1,1,1,0,0,2 5,13095,0,20200629,20201129,1,1,1,1,1,0,0,2 6,13095,0,20200629,20201129,1,1,1,1,1,0,0,2 7,13095,0,20200629,20201129,1,1,1,1,1,0,0,2 8,13095,0,20200629,20201129,1,1,1,1,1,0,0,2 9,13095,0,20200629,20201129,1,1,1,1,1,0,0,2 10,13095,0,20200629,20201129,1,1,1,1,1,0,0,2 11,13095,0,20200629,20201129,1,1,1,1,1,0,0,2 12,13095,0,20200629,20201129,1,1,1,1,1,0,0,2 13,13095,0,20200629,20201129,1,1,1,1,1,0,0,2 14,13095,0,20200629,20201129,1,1,1,1,1,0,0,2 15,13095,0,20200629,20201129,1,1,1,1,1,0,0,2

Once you get timetables.txt deduplicated, it should generate many fewer timetables and probably not run out of memory.

Also note that info in timetable_stop_order.txt is optional - for routes where all trips serve the exact same set of stops you don't need anything in that file. It is only needed for routes where some trips serve a completely different set of stops than others so you can specify the order of the stops that you'd like to appear in the timetable.

Okay, I'll try to create the timetable.txt again making everything unique.

I pushed an update to the documentation to better explain the purpose of timetable_stop_order.txt file https://gtfstohtml.com/docs/timetable-stop-order. Check it out and let me know if you have suggestions for how to make it easier to understand.

[471Q]

Yes, the updated documentation is much more comprehensible. One more thing should mention on the timetable.txt file page is that, that .txt file alone is enough to generate the timetables.
