A. SUMMARY
San Francisco International Airport Report on Monthly Passenger Traffic Statistics by Airline.

B. HOW THE DATASET IS CREATED
Data is self-reported by airlines and is only available at a monthly level

C. UPDATE PROCESS
Data updated quarterly

D. HOW TO USE THIS DATASET
Airport data is seasonal in nature, therefore any comparative analyses should be done on a period-over-period basis (i.e. January 2010 vs. January 2009) as opposed to period-to-period (i.e. January 2010 vs. February 2010). It is also important to note that fact and attribute field relationships are not always 1-to-1. For example, Passenger Counts belonging to United Airlines will appear in multiple attribute fields and are additive, which provides flexibility for the user to derive categorical Passenger Counts as desired.

Under section 3.216(d) of the San Francisco Campaign and Governmental Conduct Code, form SFEC-3.216(d) must be filed by an elected officer who either:(a) accepts a gift of transportation, lodging, or subsistence for any out-of-state travel that is paid for in part by an entity other than the City and County of San Francisco, another governmental body, or a bona-fide educational institution as defined in section 203 of the Revenue and Taxation Code, or that is paid for by the City in whole or in part with funds donated from any entity other than another governmental body or bona fide educational institution as defined in Section 203 of the Revenue and Taxation Code; or(b) reimburses the entity for the gift of transportation, lodging or subsistence in order to avoid receiving a gift.This table includes filings from March 2015 to March 2018.

This dataset was provided to the San Francisco Planning Department from the San Francisco County Transportation Authority (Transportation Authority) in March 2016. The Transportation Authority uses the San Francisco Chained Activity Model Process (SF-CHAMP) to estimate vehicle miles traveled (VMT) by private automobiles and taxis for different land use types. Travel behavior in SF-CHAMP is calibrated based on observed behavior from the California Household Travel Survey 2010-2012, Census data regarding automobile ownership rates and county-to-county worker flows, and observed vehicle counts and transit boardings. SF-CHAMP uses a synthetic population, which is a set of individual actors that represents the Bay Area’s actual population, who make simulated travel decisions for a complete day.

VMT estimates are provided for existing (2012) and future (2040) for three land use types: office, residential, and retail. For these estimates, Transportation Authority used tour-based analysis for office and residential uses and a trip-based analysis for retail uses. The aforementioned VMT estimates are provided for each transportation analysis zone within San Francisco and compared to regional averages.

Refer to March 3, 2016 San Francisco Planning Commission Transportation Sustainability Program staff report for further details.

The data is in a zipped file geodatabase (GIS) format. Geographic boundaries are Traffic Analysis Zones (TAZ's).
