# Ground Vehicles Information<no value>
As one might expect, Ground Vehicles are SimObjects representing vehicles that move on the ground. These types of SimObjects can be used in missions - for example - but are mainly used as part of the [Living World](../../../environment/living-world/living-world/), to populate [airports](../../../environment/airports-and-facilities/airports-and-facilities/). More precisely, there are two types of Ground Vehicles uses in airports:

-   **Ambient Traffic**, which are vehicles random wandering across the airport while following taxi paths
-   **Services**, which can directly interact with aircrafts for specific purposes


The latter generally require additional specific configuration in order to work properly, which is explained [here](../../../environment/living-world/airport-services/airport-services/).

As with any other SimObject, a Ground Vehicle folder generally contains a *model* folder, a *texture* folder, and a *sound* folder, or possibly several of these if the SimObject has variations. It will also have an `ai.cfg` file, and optional `camara.cfg` and `navigation_graph.cfg` files. Note that the model folder contains an `*.xml` file referencing {{< glossterm >}}lod{{< /glossterm >}}s and model behaviors, as described in the corresponding section here: `<Behaviors>`. Ground Vehicles have a single `*.cfg` file at their root folder, which is the file `sim.cfg`.

The pages linked below outline some of the general requirements for the configuration files used by all ground vehicles:

-   [sim.cfg](../../../cfg-files/sim.cfg/)
-   [sim.cfg Examples](../../../cfg-files/aircraft-sim/sim.cfg-examples)
-   [Ground Vehicle ModelBehavior Helpers](../../../models/modelbehaviors/ground-vehicle-modelbehavior-helpers/)


The following pages detail the basics of Ground Vehicle configuration for specific types of ground vehicle, whether they form a part of the Ambient Traffic or Services:

that the information on each of these pages builds on the information given in the `sim.cfg` page, so you should be aware of the contents of that page before continuing.
