I am new to GTFS and currently converting some transit data into GTFS format. It is in a pretty standard format such as:
ROUTE 01
Trip starting at 2pm (runs Monday - Friday, not xmas day)
Trip starting at 4pm (runs Monday - Friday, not xmas day)
ROUTE 02
Trip starting at 2.10pm (runs Monday - Friday, not xmas day)
Trip starting at 2.20pm (runs Monday - Friday, not xmas day)
My question is, how many entries should there be in the 'Calendars' and 'Calendar_Dates' tables for the above example?
At the moment, I'm creating a whole new 'Service' (Calendar/Calendar Dates) for each trip, so there would be 4 entries in each table for the above example. But since all the run days/run dates are the same, I could theoretically map all of the trips above to just one service.
So, should there be:
- 1 'service' per route?
- 1 'service' per trip?
or
- As small a number of services as possible for each unique combination of calendar days and calendar dates?
Clearly the third option would reduce file size but equally feels a little unintuitive.
Grateful for help and advice on this one.
Carl
