Crate synthpop

This crate describes a synthetic population that exist in a map. Currently each person’s travel behavior is modelled, but in the future, demographic and health attributes may be added. There’s a variety of ways to create these populations, scattered in other crates.

Note that “scenario” is the term currently used to describe the population. This will be renamed “soon.”

  Some users of the API (https://a-b-street.github.io/docs/tech/dev/api.html) have their own simulation input data; import it here.
• make

Structs

• ExternalPerson
• ExternalTrip
• IndividTrip
• MapBorder
• MapBorders
  Lists all border intersections of the map, broken down by mode and whether they support incoming or outgoing traffic.
• OrigPersonID
  This is an ID used by Seattle soundcast. Originally it was preserved for debugging, but that hasn’t happened in a long time. Also the format is tied to Soundcast. Consider deleting / changing.
• PersonSpec
• Scenario
  A Scenario describes all the input to a simulation. Usually a scenario covers one day.
• TrafficCounts
  This represents the number of vehicles (or trips, or something else) crossing roads and intersections over some span of time. The data could represent real observations or something from a simulation.

Enums

• ExternalTripEndpoint
• ScenarioModifier
  Transforms an existing Scenario before instantiating it.
• TripEndpoint
  Specifies where a trip begins or ends.
• TripMode
  How does a trip primarily happen?
• TripPurpose
  Lifted from Seattle’s Soundcast model, but seems general enough to use anyhere.
