# Barrier Route Element
Use barriers to close off hallways, add delays, restrict access by user role, or enforce one-way routing.
***
### When to use a Barrier
Barriers are useful when you need to influence routing but there is no door to place a Door Route Element on. Common use cases include:
* Blocking a hallway that should not be used for navigation
* Adding a delay to a route that passes through a slow area, like a security checkpoint
* Restricting access to a zone for certain App User Roles
* Enforcing one-way movement through a corridor or entrance
***
### Adding a Barrier
1. In the Actions Toolbar, click **Show Network** to make the route network visible
2. Click **Add Barrier Route Element**
3. Click on the map at the point where you want to place the barrier
4. The Barrier editor panel will open — configure the settings below
5. Click **Save**
6. Click **Reload Route Network** to apply your changes
> **Note:** Always reload the Route Network after saving changes to a barrier, otherwise the changes will not be reflected in your app.
***
### Barrier Settings
**Restrictions** Controls who can pass through this barrier.
* **Open for all** — All users can pass through. No restriction applied.
* **Open for specific App User Roles** — Only users with the selected roles can pass through. Select one or more App User Roles from the list.
* **Closed for all** — No users can pass through. The route will be blocked entirely.
**Delay (seconds)** Adds a time penalty to any route that passes through this barrier. Used in estimated travel time calculations. Useful for areas that slow people down — such as a busy intersection, a turnstile, or a steep ramp.
**Radius (meters)** Sets the radius of the barrier to ensure it correctly intersects the Route Network. Increase this value if the barrier doesn't appear to be connecting to the network paths.
**Floor Index** Sets which floor the barrier is placed on. By default this is set to the currently active floor. Change this if you need to move the barrier to a different floor.
**One-way direction (bearing)** Enforces one-way movement through this point. Enter a bearing in degrees (0–360) representing the direction users are allowed to exit. For example, a value of 45 means users can only exit heading north-east.
***
### Editing or deleting a Barrier
To edit an existing barrier, make sure the Route Network is visible (click **Show Network**), then click the barrier on the map to open its settings panel. Make your changes and click **Save**, then **Reload Route Network**.
To delete a barrier, open it and click **Delete**, then reload the Route Network.
***
> **Tip:** If you want to restrict access through a door rather than an open path, use a Door Route Element instead — it offers the same restriction options plus door-specific settings like type and snapping behaviour.
