How to properly organize minsktrans schedule parsing?

Question

Parsing

Good afternoon, I need help parsing the schedule, namely the transport schedule on the minsktrans.by website.
The schedule is stored in a text file times.txt, which is parsed on the client side. I can't figure out the data structure.
Example:

112532,1055,,16039,,0,,12345,,2,,1,,1,,1,,2,,1,,2,,2,,2,,1,,2,,14,, 112533,452,,16039,,0,,12345,,13,,2,,1,,2,,2,,2,,2,,0,,2,,1,,1,,1,,1,,2,, 112531,1090,,16039,,0,,12345,,2,,1,,1,,1,,2,,1,,3,,1,,2,,1,,2,,
