    as part of an [assignment](https://developers.google.com/maps/documentation/mobility/services/resources/glossary.md.txt#assignment), such as picking up and delivering
    a package. See also [Task types](https://developers.google.com/maps/documentation/mobility/fleet-engine/essentials/tasks-intro.md.txt#task-types) in the [Scheduled tasks](https://developers.google.com/maps/documentation/mobility/fleet-engine/essentials/tasks-intro.md.txt)

    transaction between a business and its customers. An assignment can include
    multiple [activities](https://developers.google.com/maps/documentation/mobility/services/resources/glossary.md.txt#activity), such as delivering all packages in the
    truck.

ADC
:   Application Default credentials. A method used by Google Cloud client
    libraries to automatically authenticate with Google Cloud services and APIs.
    It simplifies the process by allowing your application to use the same
    credentials in both development and production environments without code
    changes. See [How Application Default Credentials works](https://cloud.google.com/docs/authentication/application-default-credentials) for
    details.

actual
:   Modifier indicating that something has happened, as opposed to being
    [planned](https://developers.google.com/maps/documentation/mobility/services/resources/glossary.md.txt#planned). Applied to different types of data, such as a

    to the termination of
    a specific [assignment](https://developers.google.com/maps/documentation/mobility/services/resources/glossary.md.txt#assignment). An example would be one rideshare
    trip for a single person, or a shipment journey for a package delivered at
    a given [stop](https://developers.google.com/maps/documentation/mobility/services/resources/glossary.md.txt#stop). A journey is also the part of the [driver's](https://developers.google.com/maps/documentation/mobility/services/resources/glossary.md.txt#driver)
