Transit Trips

Overview

The transit trips table contains information about fully disaggregate, individual public transit trips for a typical weekday and weekend day in each season. Our data includes trips from over 300 transit agencies and 11,000 routes. Each row of data corresponds to one trip. This dataset can be utilized to generate a number of metrics including origin destination tables and transit line/agency volumes. Data is released twice a year and is currently available for 2019, 2021, 2022 and 2023. It is available for download in CSV format.

Demographic, socioeconomic and employment information about the trip taker can be added for each individual trip by joining this table with the Demographics & Employment table using the person_id and household_id fields.

Schema

Field NameContent TypeSample ValueDescription
activity_idString15323941267251300000A randomly assigned unique identifier defined for each trip. A trip is defined as travel between two locations with a discrete purpose at the origin and destination. Some intermediate stops with short dwell time may be captured within a single trip. Criteria for this dwell time may vary. Examples of trips:
• Home > Work,
• Work > Gym,
• Shop > Eat,
• Home > Starbucks drive-thru > Work
person_idString4339817784218880000A randomly assigned unique identifier for each person modeled within the synthetic population.
household_idString14408018579505000000A randomly assigned unique identifier for each household modeled within the synthetic population.
modeStringPUBLIC_TRANSITThe primary transportation mode used for the trip. A trip is often made up of multiple travel modes, such as a journey to work that includes a walk to a rail station followed by a subway ride. In this case two modes were used by the traveler during their trip, walking and public transit. Only the primary mode of travel across a set of trip segments is included. The primary mode is determined using the following ranking: 1) Public transit, 2) Driving (private auto)/Auto passenger/Taxi/TNC, 3) Biking, 4) Walking. This table is limited to the following:
• PUBLIC_TRANSIT: Trips that primarily used public transit, such as buses, light rail, and subways

• EAT: Trips to restaurants
