A. SUMMARY
This dataset contains the number of station exits from Bay Area Rapid Transit (BART) stations by day starting from January 1, 1998. This data is produced by BART and not by the City & County of San Francisco.

B. HOW THE DATASET IS CREATED
Data is simply a lightly cleaned version of the public Daily Station Exits data published by BART here: http://64.111.127.166/DSE/Daily_Station_Exits.xlsx

More information on BART ridership data is available here

C. UPDATE PROCESS
Data will update monthly when published by BART.

D. HOW TO USE THIS DATASET
Each row contains a date with the station names listed as columns and the number of exits from that station for that date as values. Station name abbreviations are used as columns but a reference table to identify full station names is available here for reference.

Note: Daily exit data for approximately 16 dates (rows) in FY 2007-08 are missing from the dataset.
