The Network Reference references the feature back to the network element. The Network Reference has been extended and the feature types which solely use Network Referencing are Maintenance, Reinstatement, Special Designation and Highways Dedication. These features will all reference back to the id of the Street feature: the USRN. Geometry will not be provided. However, where these features do not reference an entire Street feature, and are a partial reference, they will provide a Network Reference Location. This is made up of a locationDescription which provides a textual description of where the feature relates to which will be populated directly from the NSG / SSG.
The feature types which use the Network Reference Location are Maintenance, Reinstatement, Special Designation, and HighwayDedication.
The identifier of the feature being referenced; this will always be the gml:id.

When a feature in the RAMI specification occurs at a RoadNode a Node Reference will be provided. As a part of the networkRef an element attribute will be given which defines the id of the RoadNode. A location will be provided for Node References which will be the coordinates of the RoadNode the feature references. Finally, a linkReference will contain a reference to the id of the RoadLinks that are affected by the restriction. In most instances, this will be all the RoadLinks that start or end at the referenced RoadNode. However, when a RoadNode has a classification of Grade Separation, then it will only reference the RoadLinks that are at the same level as the feature. An example of this could be at a bridge with a height restriction. The height restriction will only impact the RoadLinks that are passing under the bridge.
The RoadLinks which are travelling over the bridge are not impacted by the height restriction. Therefore, the NodeReference will provide a reference to the RoadLinks which are passing under the bridge and will not reference all RoadLinks which reference the RoadNode through the start or end node references.
The feature types which use a Node Reference are RestrictionForVehicles, Hazard, and Structure.

When a feature occurs along a complete single RoadLink, a Link Reference will be used. Geometry is not provided for these features. The direction along the RoadLink for which the feature applies is supplied through the applicableDirection. If the feature applies to the RoadLink, regardless of which direction you travel along it (for example, Traffic Calming), then the value will be both directions. If the feature applies to the RoadLink in a specific direction of travel (for example, a One-Way road), the direction will be given in relation to the digitisation of the RoadLink (the order of coordinates).
The feature types which use a Link Reference are TurnRestriction and Structure.
The identifier of the feature being referenced; this will always be the gml:id of a RoadLink.

For a feature that happens at a specific point, that is not coincident with a RoadNode, a Point Reference will be used which will reference a RoadLink. The Point Reference will give the location of the point, defined as a distance value in metres from the start of the RoadLink through the atPosition attribute. In addition, the location of the point will be given by a pair of coordinates which are snapped to the RoadLink, through the atPositionGeometry attribute. Finally, the direction along the RoadLink for which the feature applies is given through the applicableDirection. If the feature applies to the RoadLink regardless of which way you travel along it (for example, a Gate), the value will be both directions. If the feature applies to the RoadLink in a specific direction of travel (for example, an Access Restriction), the direction will be defined in relation to the digitisation of the RoadLink (the order of coordinates).
The feature types which use a Point Reference are AccessRestriction, RestrictionForVehicles, Hazard, and Structure.

A Multiple Link Reference is the same as a Link Reference, except the feature will contain more than one link reference. This referencing will be used when a feature references multiple, complete RoadLinks, for example a No Turn. The order in which these features apply to the RoadLink is important to ensure the feature is being interpreted correctly and therefore the Link References in the product have been ordered to reflect this. In addition to the order, the direction will be provided in relation to the digitisation of the RoadLink and this is important in interpreting the feature. Geometry will not be provided for these features.
The feature types which use a Multiple Link Reference are TurnRestriction and Hazard.

A code list or enumeration is a controlled set of values which can be used to populate a specific column.
The OS MasterMap Highways Network – RAMI can be ordered as either full supply or change-only update (COU). The GML structure for full supply and COU is different. The differences are fundamentally the open and closing tags which will have an impact on how you choose to load the product. Examples of the different opening and closing tags can be found in GML examples. If a customer wishes to move their order from full supply to COU, then they will need to receive an initial supply and apply the COU file to an initial supply. The COU should not be applied to a full supply order.
When an order for full supply is placed, the product will contain all features for the customer’s area of interest. When a product refresh is ordered, for this type of order, the supply will contain all the features for the area of interest which will include features that have not changed. This supply mechanism will not explicitly identify which features are new, have been modified or have been removed. This can still be identified by querying the reasonForChange and the beginLifespanVersion attribute.
When an order is placed for COU, the first order received will be an initial supply. Initial supply refers to the first order that a customer takes of OS MasterMap Highways Network under the COU order type. An initial supply contains all features for the complete area covered by the order, and every feature will be an insert. Updates, which contain the latest changes to the features, are sent out automatically.
Following the initial order, a COU will be supplied, at the selected update schedule of the customer. COU only contains new features, new versions of features and information about deleted features. A feature can be deleted from the customer’s holdings for two reasons; the feature has been deleted and the id will no longer exist in the product, or the feature has moved outside of the customer’s area of interest but still exists in the national product and therefore could be reinstated in a customer’s holdings. To identify the difference between the two deletes, the reasonforchange can be used. If the value is ‘end of life’, then this feature has been permanently deleted, whilst any other change value would indicate the feature has moved outside of the holdings and could be reinstated in future. Any feature within the area of interest that has not undergone any change will not be supplied.
The features within the initial supply and COU are provided as transactions. A transaction identifies if the feature is new, modified or removed from the product. The three types of transactions are as follows:
<os:insert>
These are features which have been newly inserted into the product or the customer’s area of interest since the last product supply
<os:replace>
These are features which have had either a geometry change or an attribute change since the last product supply. The whole feature will be supplied, not just the changed attributes. The recommended action would be to completely replace the feature which currently exists in the customer’s holdings.
<os:delete>
These are features which have ceased to exist in the last product release or have moved out of the customer’s area of interest. Features which have been deleted will be supplied with the entire feature’s attribution. These features should be removed from the customer’s live data holding.
The initial supply will contain an insert transaction for all features in the customer’s holdings. The following COU supplies will have insert and replace transactions in one GML file and deleted features will be supplied in a separate file. Where a delete file has been supplied, this must be loaded before the file containing inserted and replaced features. There are examples in GML examples of the different types of transactions.
OS MasterMap Highways Network – RAMI is supplied in two formats: Geography Markup Language (GML 3.2.1) and GeoPackage. All formats are compressed into a regular zip file (.ZIP).
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.
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.

OS MasterMap Highways Network – RAMI is supplied as one GeoPackage file for GB. GeoPackage (*.gpkg) is an open, standards-based data format, as is defined by the Open Geospatial Consortium (OGC). It is designed to be a lightweight format that can contain large amounts of varied and complex data in a single, easy to distribute and ready to use file.
GeoPackage can be used in most GIS software in its native format without translation. GeoPackage attribute names are not limited in length. A GeoPackage file has no size limit, and it supports raster, vector, and database formats, making it a highly versatile solution.
The naming of attributes between GeoPackage and the Geography Markup Language (GML) file is very similar as GeoPackage files are not limited in the number of characters for an attribute name. Therefore, the following tables map the GML attribute name to the attribute name in the GeoPackage files.
The GML contains an attribute which describes the geometry of the feature; this is not applicable for a GeoPackage file as they are separated by their geometry. Please note not all GML attributes have been mapped to GeoPackage. In the tables below, a greyed-out box with an asterisk (*) marks a GeoPackage attribute that is not mapped from a GML attribute.
The Maintenance and SpecialDesignation feature types are made up with the ResponsibleAuthority feature type. The following sections illustrate what attribution makes up this data type.
The authority responsible for the street naming and numbering or maintenance.
Identification code used to identify the authority.

This section describes how OS MasterMap is defined in GML. An understanding of XML (Extensible Markup Language) and XML schema is required.
GML is an XML grammar for expressing geographic features. GML serves as a modelling language for geographic systems as well as an open interchange format for geographic transactions on the Internet. More information can be found on the Open Geospatial Consortium (OGC): http://www.opengeospatial.org/standards/gml.
The XML specifications that GML is based on are available from the World Wide Web Consortium (W3C): http://www.w3.org.
Information about Unicode and UTF-8, the character encoding we have chosen, is available on the Unicode Consortium website: http://www.unicode.org.
XML schemas are used to define and validate the format and content of GML. The GML 3.2 specification provides a set of schemas that define the GML feature constructs and geometric types. These are designed to be used as a basis for building application-specific schemas, which define the data content.
The OS MasterMap Highways Network RAMI product uses the following application schemas, which are referenced by the data:
RoutingAndAssetManagement.xsd
GeneralNetwork.xsd
OSProducts.xsd
The RoutingAndAssetManagement.xsd defines the features which make up the RAMI features. Therefore, it imports the INSPIRE transport network road application schema.
The GeneralNetwork.xsd defines how the RAMI features reference back to the network. Therefore, it imports the INSPIRE network application schema. Through the INSPIRE schemas, both the RoutingAndAssetManagement.xsd and GeneralNetwork.xsd import the GML 3.2 schemas. These in turn import schemas produced by the W3C, which are available from the W3C website at http://www.w3.org/XML/1998/namespace.html.
The OSProducts.xsd defines the feature collection and feature members. In addition, this application schema will define the transactions used for a COU supply.
The RAMI schema document defines the http://namespaces.os.uk/mastermap/routingAndAssetManagement/2.1 namespace;
this is defined in the XSD at: http://www.os.uk/xml/schema/highwaysnetwork/2.1/RoutingAndAssetManagement.xsd.
The General Network schema document defines the http://namespaces.os.uk/mastermap/generalNetwork/2.0 namespace;
this is defined in the XSD at: https://www.ordnancesurvey.co.uk/xml/schema/network/2.0/generalNetwork.xsd.
The Highways Dedication schema document defines the http://namespaces.os.uk/mastermap/highwayDedication/1.0 namespace;
this is defined in the XSD at: https://www.ordnancesurvey.co.uk/xml/schema/highwaysnetwork/1.0/HighwayDedication.xsd.
The application schema uses the following XML namespaces, for which definitions are available as given in the following table:
OS MasterMap Highways Network – RAMI is a relational product. This results in there being relationships between different feature types. This section summarises how the different feature types relate to one another, and which attributes are the primary and foreign keys for the RAMI feature. For information on the Roads features, please see the Roads Technical Specification.
The following table identifies how the feature types relate to one another and which attributes are the primary and foreign keys. This is also represented diagrammatically in the figure below the table. The attribute at the arrowhead is the primary key, and the attribute at the base of the arrow is the foreign key.
| Source Feature Type | Foreign Key Attribute | Destination Feature Type | Primary Key Attribute |
|---|---|---|---|
The RAMI product contains the base road network and RAMI features, which reference back to the network. The base road network features are detailed in the Roads Technical Specification. The current specification focuses on RAMI.
RAMI has been categorised into the following themes:
Rights and Restrictions: Defines properties that restrict, regulate or prohibit the use of the network by traffic such as turn restrictions, or access and use restrictions which may affect the allowable route for users.
Advisory Information: These provide additional information that may affect a driver’s preferred choice of route or highlight potential hazards such as the presence of a toll, ford, or level crossing.
Asset Management: Provides additional information to support the management of Highways Assets by Highways and Roads Authorities such as detailed physical characteristics relating to the asset (reinstatement), road maintenance responsibility, and whether it has any special designations
RAMI is related back to features in the OS MasterMap Highways Network – Roads product using Network Referencing, through the networkRef attribute. All RAMI features extend the INSPIRE NetworkProperty class. This allows several types of Network Referencing to relate the RAMI to the relevant feature:
Network Reference: This is used to relate the information to a Street.
Node Reference: This is used to relate the information to a RoadNode.
Link Reference: This is used to relate the information to a complete RoadLink.
Multiple Link Reference: This is used to relate the information to more than one complete RoadLink.
Point Reference: This is used when the information is related to a specific point along a RoadLink.
Linear Reference: This is used to relate the information to a specific section of a RoadLink. This type of referencing is not used in the RAMI specification.
The different types of Network Referencing all extend the INSPIRE Network Reference data type.
In the INSPIRE specification, the networkRef is a voidable field. For all features in the RAMI specification, the networkRef will never be voided.
The Rights and Restrictions sub-theme includes properties that prohibit, restrict or regulate the use of the network by traffic. Rights and Restrictions are typically defined through legislation, including the Traffic Regulation Order (TRO) made under the Road Traffic Regulation Act 1984.
The following types of rights and restrictions are in the scope of the current product:
Access Restrictions
Turn Restrictions
Restrictions For Vehicles (Height, Weight, Width and Length restrictions)
Highways Dedications (indications of Rights of Way)
Rights and Restrictions features record the effect and nature of the real-world restriction or environmental factors. However, this is not always possible as restrictions may manifest in many different ways yet have the same effect.
For example, a single restriction may consist of a one-way street that has a no entry sign, no right/left turn sign and/or mandatory turn signs on the approach roads. This is represented in the simplest way by recording a one-way street. To ensure a level of consistency, a hierarchy is used when more than one restriction that has the same effect occurs at a given location. Only the restriction that has the highest priority will be captured.
| Priority | Restriction |
|---|---|
Therefore, Rights and Restrictions primarily model the effect of any restriction in the simplest possible way and secondary to this is recording the real-world manifestation.
Each feature within the RAMI theme will have the following common attribution:
gml:id, gml:identifier and inspireId
beginLifespanVersion
reasonForChange
validFrom
This is assigned a nilReason value unknown for most features.
The RAMI product holds information on restrictions which apply to a temporal period. The different Temporal Properties have been categorised and the different categories are detailed below. In addition, they have been given a hierarchy within the RAMI product which is illustrated in the figure below Temporal Properties are applied to four Feature Types in RAMI: AccessRestrictions, HighwayDedication, TurnRestrictions and SpecialDesignation.
A Named Date would be when a restriction applies to a specified date which is named. For example, All Year or January. There are no further sub-categories of a Named Date.
A Date Range is provided when a restriction applies between two dates and there will always be a start date and an end date. These two dates can be specified using two different data types: either StartDate and EndDate or StartMonthDay or EndMonthDay.
The StartDate and EndDate will always be used for Date Ranges for Special Designation features. These are formatted as YYYY-MM-DD, for example, 2016-09-20. The StartMonthDay and EndMonthDay will always be used for Access Restrictions and Turn Restrictions. These are formatted as --MM—DD, for example, -- 03—23.
A Day Period would be a restriction which applies on a specified day. A Day Period is made up of the following properties:
Named Day – A restriction which applies to a specified day which is named, for example, Monday or Weekends.
Named Period – A restriction which applies to a specified period which is named, for example, School Holidays.
Time Period – A time period is made up of a further two properties:
Named Time – A restriction which applies to a specified time period which is named. Does not necessarily relate to the same time each day consistently across the country, for example, Peak Time.
Time Range – When a restriction applies between two specified times which will always have a start time and an end time. These data types are formatted as HH:MM:SS and will use the 24hr clock, for example, 16:30:00.
A turn restriction is a restriction based upon a vehicle manoeuvre. This type of restriction includes prohibitive driving instructions, mandatory driving instructions and implicit restrictions. Prohibited instructions are indicated by road signs within a red circle, examples include No U Turn, No Right Turn or No Left Turn. These can include exceptions to the instruction and are typically elements like Except for Buses. Mandatory driving instructions are indicated by road signs within a blue circle or painted on the roadway such as Turn Right, Ahead Only and No Left Turn. Implicit restrictions occur where a turn is not signed as prohibited but would not be a normal manoeuvre. For example, where a road splits around a traffic island or at complex junctions where additional geometry has been captured to reflect the traffic flow. These are not differentiated from actual signed restrictions.
A Turn Restriction will reference back to the Roads product through Link References and Multiple Link References.

RestrictionForVehicles are constraints that apply to the vehicles based on their physical characteristics: height, weight, width and length. These are required to protect structures such as bridges and tunnels from damage, or to restrict/prohibit use by vehicles that exceed specific dimensions, usually for environmental reasons.
RestrictionForVehicles has been extended to support the full definition of height, weight, width and length restrictions as defined in the UK to ensure that they can:

This technical specification provides detailed technical information about OS MasterMap Highways Network – RAMI. It is targeted at technical users and software developers.
The OS MasterMap Highways Network is the authoritative highway network for Great Britain. It brings together Ordnance Survey’s large-scale road and path content, the National Street Gazetteer (NSG), the Trunk Road Street Gazetteer (TRSG) and the Scottish Street Gazetteer (SSG).
OS MasterMap Highways Network is made up of four product schemas: Linear Highway Network, Highways Dedication, Routing and Asset Management Information and Highways Water Transport Network. These four schemas, shown in the diagram below, create three products which are a part of the OS MasterMap Highways Network 'family':
OS MasterMap Highways Network – Roads
OS MasterMap Highways Network – Routing and Asset Management Information
OS MasterMap Highways Network – Paths
This technical specification covers the OS MasterMap Highways Network – Routing and Asset Management Information (from here, referred to as RAMI) product specification, providing a focus on the RAMI features. To use this product, you will have received the features which make up the Roads product. For further details on the Roads or Paths products, please see their respective Technical Specifications.
All features that comprise the OS MasterMap Highways Network product will be assigned a persistent identifier, which in most instances is an Ordnance Survey TOID (Topographic Identifier). For features which have originated from the National Street Gazetteer, the persistent identifier will be either a Unique Street Reference Number (USRN) for Street features or a unique ID for Maintenance, Reinstatement, Special Designation and Highways Dedication.
Identifiers shall be encoded in three properties in the data:
gml:id – This feature identifier consists of the shorthand prefix namespace and local identifier which is used to uniquely identify and reference the feature within the dataset, for example, osgb4000000009461245.
gml:identifier – This is a global feature identifier and can be used to identify and reference the feature within other datasets, for example, http://data.os.uk/id/4000000009461245.
inspireID – This is a complex property made up of a localId, namespace and versionId which uniquely identifies the feature and version within an INSPIRE dataset.
Where features have come from OS MasterMap ITN Layer, the identifier will be persistent and correspond to the same feature in ITN.
The gml:id is used throughout the OS MasterMap Highways Network products as the identifier used to reference to other features.
TOIDs (Topographic Identifiers) are strings of up to twenty characters which comprise two parts:
Namespace: This is either a HTTP URI (http://data.os.uk/) or a shorthand prefix (osgb)
Local identifier: A 16-digit numeric string (0-9)
gml:id – ‘osgb4000000009461245’
localId – ‘4000000009461245’
identifier - ‘http://data.os.uk/4000000009461245’
USRNs (Unique Street Reference Numbers) are strings of up to 12 characters which consist of 2 parts:
Namespace: This is either a HTTP URI or shorthand prefix (‘usrn’)
Local identifier: Up to an 8-digit numeric string (0-9)
gml:id – ‘usrn82101225’
localId – ‘82101225’
identifier - ‘http://data.os.uk/82101225’
Although the gml:id is the identifier used for referencing features in OS MasterMap Highways Network products, the localId is the identifier used by the National Street Gazetteer, National Land and Property Gazetteer and the OS AddressBase family of products.
Unique IDs for Maintenance, Reinstatement, and Special Designation are strings of up to 17 characters which consist of two parts:
Namespace: This is either a HTTP URI (http://data.os.uk/) or shorthand prefix (‘id_’)
Local identifier: 14-character alphanumeric string
The ID for HighwayDedication is a string of up to 25 characters comprised of the characters “esu” followed by three parts separated by “_” (underscore):
LHA authority code
ESU it references
Dedication code in the NSG
For example: esu4720_4280330430163_8, esu4720_4280340431456_11
gml:id – ‘id_3700MA01862142’ or ‘esu4720_4280330430163_8’
localId – ‘3700MA01862142’ or ‘esu4720_4280330430163_8’
identifier - ‘http://data.os.uk/3700MA01862142’ or ‘https://data.os.uk/id/ esu4720_4280330430163_8’
OS MasterMap Highways Network – RAMI will be supplied in two formats: Geography Markup Language (GML 3.2.1) and GeoPackage. Both formats are compressed into a regular zip file (.zip).
OS MasterMap Highways Network– Roads and OS MasterMap Highways Network – Paths will be supplied in three formats: Geography Markup Language (GML 3.2.1), GeoPackage and vector tiles. All formats are compressed into a regular zip file (.zip).
OS MasterMap Highways Network extends the INSPIRE Transport Networks (Road and Water) Technical Specification (version 3.2).
OS MasterMap Generic Network model extends the INSPIRE Base Models - Generic Network Model (version 3.0rc3).
OS MasterMap Highways Network extends the INSPIRE Specification to include the additional properties required by BS 7666-1:2006 defined within the National Street Gazetteer (NSG) Data Transfer Format (DTF) and Scottish DTF (SDTF) to ensure that conformance to both INSPIRE and BS7666-1:2006 can be achieved.
The data structure is described by means of UML class diagrams and accompanying data dictionary tables. The specification conforms to the rules for application schema specified in ISO 19103 Conceptual schema language and ISO 19109 Rules for application schema, as adopted by INSPIRE.
Colour conventions have been used in the diagrams and tables to allow users to easily distinguish the INSPIRE feature classes (coloured grey) from the Ordnance Survey feature classes which extend the INSPIRE specifications (coloured orange). All code list classes are coloured blue, enumeration classes are green and data types/union classes are purple (see diagram below).
The data dictionary tables use orange for a feature type, blue for a code list, green for enumerations, and purple for data types.
Class names are conceptually meaningful names (singular noun) in UpperCamelCase.
Class names end in “Value” where the class is assigned the stereotype <<CodeList>> or <<Enumeration>>.
Class names shall end in “Type” where the class is assigned the stereotype <<DataType>>.
Property names (attributes and associations) are in lowerCamelCase.
The following stereotypes are used on UML elements:
Constraints are defined on the Class using human readable language only. Constraints are displayed on class diagrams below. These constraints are used to define co-constraints or restrict INSPIRE properties only.
There are three key types of relationship defined between classes:
Generalisation/Specialisation – used to denote either:
An extension relationship. The target class represents the same real-world entity and is extending it to include additional properties not defined on the parent class.
This class has the same name as the class it is extending.
Or:
A sub-typing relationship. The target class defines a specialised sub-type of parent feature. For example, TransportNode is a specialised sub-type of a generic Node class.
Directed Association – used to denote relationships between features. These relationships are encoded as references to the related feature via the identifier assigned in the gml:id. The directed end shall be assigned a name which describes the relationship between the two features and a multiplicity.
Aggregation – used to denote part-of relationships. Aggregations are used to describe loose part-of relationships. If the parent feature ceases to exist, then the part feature can continue to exist. For example, a Road Name may cease to exist, but the Road will still exist.
This technical specification includes the following sections:
The SpecialDesignation feature type has the property ‘designationType’, which has the type SpecialDesignationTypeValue. The following table identifies the codes used to populate this field and a description for each code.
SpecialDesignationTypeValue coverage varies between LHAs and the individual codes. While coverage for statutory designations is good overall, coverage for some other values may be sporadic and inconsistent.

| Code | Description |
|---|---|
The HighwayDedication feature has the field ‘dedication’, which has the value populated from DedicationValue. The following table identifies the codes used to populate this field and a description for each code. These codes conform to the legal categories of highway as defined in the Highway Act 1980 and Countryside and Rights of Way Act 2000, with the exception of No Dedication Or Dedication Unknown.
Dedications indicate the legal access status for a given feature only; no indication as to its physical accessibility is made in this attribute.

This includes environmentally sensitive areas, such as sites of specific scientific interest and ancient monuments, or specially cultivated areas containing shrubs, plants or bulbs which shall be reinstated using the same or similar species. In Scotland, these are designations not made by Roads Authorities which place restrictions on activities, for which permission subject to conditions may or may not be granted, which can be carried out within or adjacent to the designated area. Consequently, any streets which pass through such designated areas are covered by any restrictions imposed by the designation.
Hazardous Material
Indication of hazardous materials that could be exposed or disturbed when roads are excavated or planed, for example, coal tar. This code is not used in England and Wales.
HGV Approved Routes
Optional designation that allows Works Promoters to consider the impact on HGVs of restricted traffic flow or alerts the Works Promoter that wide vehicles are commonplace. This code is not used in Scotland.
Level Crossing Safety Zone
Optional designation created by a Railway Operator, Network Rail or a Roads Authority. It identifies an area around a level crossing where, if occupied to carry out works, there is a risk of traffic obstructing the crossing.
Local Considerations
Optional designation that should be used to inform the Works Promoter of any special schemes that may impact working, for example, noise levels. This code is not used in Scotland.
Parking Bays And Restrictions
Optional designation that provides details of streets with parking meters, residents parking bays and parking restrictions such as yellow lines, red routes, and other permanent parking restrictions. This code is not used in Scotland.
Pedestrian Crossings, Traffic Signals And Traffic Sensors
Optional designation that captures streets that have a pedestrian crossing, permanent traffic signals or traffic sensors. For Scotland, this code also includes Loop in Road Surface. Loops include traffic signal detectors, vehicle counting and ice detection cables that are generally close to the surface of the road.
Pipelines And Specialist Cables
Optional designation that is created by the Local Highway Authority on behalf of the private sector oil or gas pipeline owner. This designation should be treated as a reminder to consult further, not as an absolute indicator of the nature of the pipeline or cable. For Scotland, this code also includes Apparatus at Shallow Depth which details apparatus placed at a shallower than recommended depth.
Priority Lanes
Optional designation that allows the Local Highway Authority to identify the location of bus lanes, and Cycle Routes in the street. This code is not used in Scotland.
Proposed Special Engineering Difficulty
Optional designation used to identify new streets or assets of extraordinary construction. One typical use is to identify the location of a designation during any consultation period. On conclusion of the consultation period this feature will typically become a Special Engineering Difficulty (SED). This code is not used in Scotland.
Road Trees
These are trees that the Roads Authority are responsible for, which grow near or within the road boundary (including the verge, footway, etc.). This code is not used in England and Wales.
Service Strips
These are areas, usually found in housing developments, abutting shared use surfaces and should be of 2m width, where the services to the housing are located. This code is not used in England and Wales.
Special Event
Optional designation that provides early awareness of special events to Work Promoters to enable them to consider any actions that they may need to take to avoid any works taking place on the street during the time(s) of the Special Event. This code is not used in Scotland.
Speed Limits
Optional designation that provides information about the speed limit applicable for the street. Only speed limits (signed or as per the legal order) over 40mph are recorded as standard with some LHAs providing 30mph speed limits as well. This data is intended to be used for planning of traffic management and works safety measures. This code is not used in Scotland.
Strategic Route
Optional designation that is used by Local Highway Authorities to identify Strategic Routes, such as the Primary Route Network. Strategic Routes are identified by the Highways Agency, TfL in London and the South Wales Trunk Road Agent (SWTRA) and North & Mid Wales Trunk Road Agent (NMWTRA) in Wales. This code is not used in Scotland.
Street Lighting
Optional designation that helps Works Promoters to carry out works in the evenings and at nights by providing relevant information about Street lighting. It is particularly useful for when Part night lighting where a council has a policy of turning lights off during specific hours. This code is not used in Scotland.
Streets Subject To Early Notification Of Immediate Activities
Optional designation that enables street authorities to designate streets that are particularly vulnerable to traffic. Work Promoters are required to provide early warning of activities to the authority immediately after the activity has commenced. This code is not used in Scotland.
Structures
For England and Wales, this is an optional designation used by asset owners to identify the existence of a structure that has not been designated as an SED. In cases where this identifies a Bridge, Works Promoters should regard it as a reminder that under Section 88 they must consult the Bridge Authority prior to serving Notices. For Scotland, this includes over-bridges and under-bridges as well as other structures including retaining walls, gantries, pipelines and cellars.
Traffic Calming Features
Traffic Calming Features include islands, build-outs, cushions, raised tables etc. This code is not used in England and Wales.
Traffic Sensitive Side Road When Temp Traffic Control is Employed
A traffic sensitivity designation applied to the first 50m (or complete length, whichever is shorter) of an adjoining street that has a junction with that traffic sensitive street. This code is used where road works on the adjoining street could cause delays on the traffic sensitive route. This code is not used in England and Wales.
Transport Authority Critical Apparatus
Optional designation that provides details of transport authority apparatus critical to operations of that authority which if damaged or if interrupted could disrupt or temporarily stop services (for example, HV cables to a rail network). This code is not used in Scotland.
Unusual Traffic Layout
Optional designation that provides details of where the layout of existing traffic signs, road markings, studs or verge markers is not in accordance with the Traffic Signs Manual. This code is not used in Scotland.

Highway dedication indicates which types of user have access to the given section of the Highway.
Against every section of geometry supplied by the local highway authority, there will be one of eight different types of Highway Dedication defined in the Highways Act 1980 and the Countryside and Rights of Way Act 2000 which determines the Highway user access.
There can only be one Highway Dedication type applied to the geometry at any given date or time. It is likely that more than one Highway Dedication type applies to a section of Highway (i.e. a highway open to all vehicles will also have pedestrian way or footway access). The following table gives the order of priority where the highway dedications under each is inferred:
| Priority | Highway Dedication |
|---|---|
*Motorways and Cycle Tracks (not Cycle Ways) impose restrictions on all other Highway users.
The Highway Dedication also identifies if the feature forms part of a National Cycle Route, Public Right of Way, Quiet Route, or Physical Obstruction, or if a Planning Order or Vehicular Traffic order exists.
The Highway dedication value is only an inference of where a Public Right of Way exists and therefore not the definitive record of Public Rights of Way; that is in the definitive map held by the relevant authority.
A Highway Dedication feature will reference back to the Path Network through Network Reference and will reference a RoadLink or Street Feature.
The Highway dedication feature type is not extended to Scotland because this information does not exist in the source local authority data.
Definition of which type of Highway user has access to a particular section of the Highway.

Maintenance provides information about whether the road is maintained at public expense by a national or local highway authority, a road authority, or is maintained by another responsible organisation (i.e. not maintained at public expense). If a path is prospectively maintainable at public expense, then this is not currently maintained by a road or highway authority, but the responsible organisation has started the process for a highway or road authority to become responsible for the maintenance of the street at public expense.
Maintenance responsibility is not an indication of ownership.
A Maintenance feature will reference back to the Roads product through Network Reference and will reference a Street Feature. Features which are a partial reference will provide a Network Reference Location. For more information on Network References, see Routing and Asset Management feature information.
Indication of whether the highway is maintained by a Highways Authority, Local Highways Authority, Road Authority or privately.
