MARTA Ridership data dictionary

[Fizzy Fan]

Hello All,

I am Fizzy, a Ph.D. student at Georgia Tech. I am working on an emission analysis that looks at the GTFS and MARTA ridership data. When trying to combine the two datasets, I realized that the trip ID does not seem to match. Does anyone know where can I possibly find the data dictionary for MARTA ridership data, or how the trip ID is made for both datasets?

Thanks!

Fizzy

(sorry I kept confusing myself and replying to you personally... ignore my duplicate emails)

Try the older zips from https://transitfeeds.com/p/marta/65

My impression: MARTA doesn't publish historical/outdated trips in the zip link on their site. The zip they keep updated has future trips/schedules for Google to import, so it has them ready by the time their service schedules arrive. You can find the applicable dates in the calendar.csv file I believe.
