After running the "Count Trips on Lines" tool of the BetterBusBuffers toolbox, I encounter the following error after running step 2, "count trips on lines:"
"There is no transit service during this time window. No service_ids cover the weekday or specific date you have selected."
On further inspection of the GTFS package's calendar.txt file, I find that every one of the [day of week] fields is entered as zero, which seems unusual. Original GTFS package is attached.
Any ideas for a workaround?
