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 Name | Content Type | Sample Value | Description |
---|---|---|---|
activity_id | String | 15323941267251300000 | A 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_id | String | 4339817784218880000 | A randomly assigned unique identifier for each person modeled within the synthetic population. |
household_id | String | 14408018579505000000 | A randomly assigned unique identifier for each household modeled within the synthetic population. |
mode | String | PUBLIC_TRANSIT | The 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 |
travel_purpose | String | WORK | The destination activity assigned to a synthetic person. For example, if a person is traveling to work, the purpose of the trip is 'Work,' whereas if a person is traveling to a restaurant the activity is 'Eat.' Valid values are: • COMMERCIAL: Trips by medium and heavy trucks for deliveries and other commercial purposes • EAT: Trips to restaurants • HOME: Trips where the destination is the person's home • LODGING: Trips by visitors to overnight accommodation such as a hotel • MAINTENANCE: Trips to hairdressers, auto shops, banks, and a variety of other locations for the purpose of conducting errands • OTHER: Catch-all category for all other trips not assigned any of the purposes listed herein • RECREATION: Trips to recreational destinations such as parks and swimming pools • REGION_DEPARTURE: Trips by visitors to a port-of-exit, such as an airport, or major train station • SCHOOL: Trips to schools such as community colleges and universities • SHOP: Trips to stores and other commercial centers • SOCIAL: Trips for social activities • STAGE: Trips made by non-residents that start and end outside the region • WORK: Trips where the destination is the person's workplace • WORK FROM HOME: Trips where a resident is returning home to work (specifically for residents who are working from home on the modeled day). For example, if a person goes out to lunch during the work day, their return trip home will be labeled “work_from_home" |
tour_type | String | COMMUTE | Indicates what type of tour included this trip. Tours are travel events that start at one location and return to that same location. For example, when a person travels to work and returns home, it is a home-based work tour. A tour can have two or more trips. Valid values are: • WORK_BASED: Tours that started and ended at work, excluding commute e.g. Work > Eat > Work • COMMUTE: Tours from home to work and back home including intermediate stops at other destinations e.g. Home > Recreation > Work > Shop > Home • OTHER_HOME_BASED: Tours that started and ended at home, excluding commutes e.g. Home > Shop > Eat > Home |
previous_activity_type | String | HOME | The activity assigned to a synthetic person prior to starting travel. Valid values are: • COMMERCIAL: Trips by medium and heavy trucks for deliveries and other commercial purposes • EAT: Trips to restaurants • HOME: Trips where the destination is the person's home • LODGING: Trips by visitors to overnight accommodation such as a hotel • MAINTENANCE: Trips to hairdressers, auto shops, banks, and a variety of other locations • OTHER: Catch all category for all other trips not assigned any of the purposes listed herein • RECREATION: Trips to recreational destinations such as parks and swimming pools • REGION_DEPARTURE: Trips by visitors to a port-of-exit, such as an airport, or major train station • SCHOOL: Trips to schools such as community colleges and universities • SHOP: Trips to stores and other commercial centers • SOCIAL: Trips for social activities • STAGE: Trips made by non-residents that start and end outside the region • WORK: Trips where the destination is the person's workplace |
