Error when running BetterBusBuffers "Count Trips on Lines" tool

[DavidPerlmutter]

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?

It looks like this agency just decided to explicitly turn on service using the calendar_dates.txt file for specific dates rather than including a regular service defined in calendar.txt.  To successfully run the BetterBusBuffers tools, you should use a specific YYYYMMDD date for the input date instead of a weekday.

Thank you, Melinda! This seems to have fixed the problem.
