Webinar June 28th: Making Vision Zero a Reality, Data-Driven Policy + Infrastructure Interventions for All

Places

Replica Places is a high-fidelity simulation that accurately represents the population and its travel patterns.

Customers use Places data to improve planning and monitoring of transportation and land use systems, and to make decisions related to the ways people interact with the built environment.

Places is the world’s only calibrated travel demand model delivered at nationwide scale offered via software-as-a-service (SaaS). It is delivered in a pioneering privacy-sensitive approach.

The Places dataset is a complete trip and population table for a typical weekday and typical weekend day for the selected season and region. Places data is accessible through Replica’s web-based platform and through direct database access.

Replica Places megaregions cover geographies that include between 10 million and 50 million residents. Each data table is cross-tabular, meaning it is linked to other tables through common IDs, including person_id (the person making the trip), activity_id (the trip), or route_id (transit routes or network links used for a trip). 

Data can be filtered on any single attribute or combination of attributes. Each row of data in the simulation output reflects a single trip, with characteristics about the trip (e.g., origin, destination, mode, purpose, routing, duration) and trip taker (e.g., age, race/ethnicity, income, home location, work/school location).

Trip Table

The Places trip table contains the unique records and associated attributes for the trips between origin and destination points. Trip data represents the modeled output for a typical Thursday or Saturday during a three-month Replica season.

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:
• 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.

Valid values are:
• BIKING:Trips made by people biking. Replica does not model scooter trips and does not separate out e-bike trips
• CARPOOL:Trips made by passengers in private auto vehicles. Sum Carpool and Private Auto trips to get the total number of people who traveled in private autos
• COMMERCIAL:Trips made by medium and heavy trucks
• ON_DEMAND_AUTO:Trips made by passengers in a Taxi or using a Transportation Network Company (TNC) such as Uber or Lyft
• OTHER_TRAVEL_MODE
• PRIVATE_AUTO:Trips made by drivers in private auto vehicles
• PUBLIC_TRANSIT:Trips that primarily used public transit, such as buses, light rail, and subways
• WALKING:Trips made by people walking
travel_purpose

• WORK_BASED: Tours that started and ended at work, excluding commute.
For example: Work > Eat > Work

Network Volumes Table

The Places network volumes table contains total estimated trip counts by mode for each network link within a given region. The trip counts represent the amount of traffic across the link on a typical Thursday during the given Replica season.

Network links (or, edges) are the streets or pathways upon which vehicles or people can travel. A single street is typically split into multiple segments, with the split points set at street intersections. Two way streets are modeled with separate network links, one for each direction of travel.

Arterial network links include freeways, highways, primary, secondary, and tertiary segments. The functional classification defined for the segments (freeways, highways, primary, secondary, and tertiary) are derived from OpenStreetMap street data. Most residential streets and service lanes are excluded from this dataset.
