| enclosed traffic area | <p>The road node is situated inside and/or represents an enclosed traffic area.</p><p>A traffic area is an area with no internal structure of legally defined driving directions. At least two roads are connected to the area.</p> |
| Junction              | Three or more road links intersect at the road node.                                                                                                                                                                                |
| level crossing        | A railway crosses a road on the same level at the position of the road node.                                                                                                                                                        |
| pseudo node           | Exactly two road links connect to the road node.                                                                                                                                                                                    |
| road end              | Only one road link connects to the road node. It signifies the end of a road.                                                                                                                                                       |

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.os.uk/os-downloads/products/transport-network-portfolio/os-mastermap-highways-network-fundamentals/os-mastermap-highways-network-code-lists/formofroadnodevalue.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
