Expand description
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.”
Modules
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.
Structs
Lists all border intersections of the map, broken down by mode and whether they support incoming or outgoing traffic.
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.
A Scenario describes all the input to a simulation. Usually a scenario covers one day.
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
Transforms an existing Scenario before instantiating it.
Specifies where a trip begins or ends.
How does a trip primarily happen?
Lifted from Seattle’s Soundcast model, but seems general enough to use anyhere.
