Bay Area Rapid Transit (BART)

Opened in 1972Serves counties of San Francisco, Alameda, Contra Costa, and Northern part of San MateoDoes NOT serve counties of Santa Clara, Marin, or the rest of San Mateoyou are hereMy commute is Rockridge Pleasant Hill/Contra Costa Centre2Bay Area Rapid Transit (BART)BART fares are set with a mileage-based formula, therefore time-based passes (e.g., weekly or monthly) are not available. http://bart.gov/tickets/index.aspx

Bay Area Rapid Transit (BART)BART fares are set with a mileage-based formula, therefore time-based passes (e.g., weekly or monthly) are not available. http://bart.gov/tickets/index.aspx

Lets figure out the formula! For every trip, we needThe fareMiles traveled

1. BARTs Fare Table

This is an excerpt from http://www.bart.gov/docs/community_meetings/March_2012/1.4_fare%20table.pdf Highlight Millbrae North Berkeley [1, 1]. $4.9052. Google Maps Driving Directions

Proxy for miles traveled on BARTTransbay tube ~ Bay Bridge6Dataset

Blue = no transbay tube. Orange = transbaySquare = non-airport (lower half). Triangle = airport (upper half)8

TransBay comes from geocoding each station, and then seeing if the trip begins/ends on different sides of the BayThanks to Statisfaction Blog for the geocode functionshttp://statisfaction.wordpress.com/2011/10/05/calling-google-maps-api-from-r/ I set 1.75 to be the intercept because I know its the minimum fare11

Model Residuals = Actual Fare Predicted FareResidual = Actual - PredictedProblems: Fremont SFO: driving, you take the San Mateo Bridge, so driving miles are much fewer than BART miles
