# AddExcludedPedestrianToSystem

### Description

Excluded pedestrians are a special kind of pedestrians marked as **Don't Instantiate** inside the Pedestrian Pool. Those pedestrians will not be instantiated by the system unless the user specifies it to be instantiated. Read more about them [Pedestrian Pool](/mobile-pedestrian-system/setup-guide/pedestrian-pool.md)

The AddExcludedVehicleToSystem adds a previously excluded pedestrian back to the Pedestrian System and the pedestrian behaves normally.

### Declaration

```csharp
public static void AddExcludedPedestrianToSystem(int pedestrianIndex)
```

### Parameters

<table><thead><tr><th width="261">Name</th><th>Description</th></tr></thead><tbody><tr><td><strong>pedestrianIndex</strong></td><td>The index of the pedestrian.</td></tr></tbody></table>
