This section describes the features which make up OS MasterMap Highways Network - Routing and Asset Management advisory information. The attributes associated with these feature types are listed below along with a brief description of their data properties.
The name of the attribute and what it is describing.
The nature of the attribute, for example a numeric value or a code list value.
The length of the attribute provided (optional).
Describes how many times this element is expected to be populated in the data. An attribute may be optional or mandatory within the product. These are denoted by:
‘1’ – there must be a value.
‘0..1’ – population is optional but a maximum of one attribute will be returned These values may be used in combination.
These are locations which are hazardous, and caution should be taken to ensure safe travel. Hazards are usually signed using the warning sign through a red triangle.
A Hazard will reference back to the Roads product through a Node Reference, Point Reference or Multiple Link Reference. For more information on these different types of Network References, see the common attribution page.
A location where a threat is imposed and caution should be taken.
Unique identifier, for Hazard this is a TOID.

Advisory Information provides additional information relating to the highway that affects traffic movement such as:
Hazards: These are locations which are dangerous, and caution should be taken to ensure safe travel. Examples include Fords and Dangerous Bends.
Structures: These are built features which relate to the highway. Examples include Barriers, Bridges and Tunnels.
These indicate the location of key structures related to the highway network. These may be:
Barriers: Structures or equipment constructed to control, obstruct or prevent passage or access
Bridges and Tunnels
Crossings and Signals: Equipment such as traffic signals, and locations that control the flow of traffic
A Structure will reference back to the Roads product through a Node Reference, Link Reference or Point Reference.
A built feature with relation to the highway network.
Unique identifier, for Structure this is a TOID.
