The script in the metrotransit-data/ directory will fetch schedule data for the Twin Cities Metro Transit. This data is updated weekly.
The 00-fetch-data.R script should be executed in the metrotransit-data/ directory. It fetches the data and saves some of the tables as .rds files. The bus app will read in the .rds files for route information.
