The Department for Transport (DFT) has published a new âTechnical Specification for Electronic Transfer of Notices (EToN)' to support the 1991 New Roads and Street Works Act. This determines the NSG's USRN (Unique Street Reference Number) to be the method of street identification for these notices.
Listing over one million streets, the NSG is the composite street index for the whole of England and Wales and is used by local government and those organisations that work on or around highways, as the definitive reference for co-ordinating street works and managing the road network. This last responsibility was devolved to Local Authorities with the introduction of the Traffic Management Act in 2004.
The new DFT specification also specifies the use of âlevel three' data, meaning that the NSG will be used to deliver full road geometry i.e. every twist and turn as opposed to start and end points for roads and streets. Using BS7666 (the British Standard designed for recording street, land and property information), the NSG was designed to be application independent with street works being the first National implementation.With all 172 Highways Authorities now providing regular updates to the hub managed by Intelligent Addressing the NSG is now fit for purpose for this first implementation.
"As a result of working closely with all the Highway Authorities in England and Wales, as well as other bodies with an interest in highways, such as DfT, Transport for London, Network Rail and the Highways Agency, the quality and currency of the NSG has improved enormously", said Nick Turner the NSG custodian.
The NSG is a local government initiative to create an unambiguous referencing system, using Unique Street Reference Numbers (USRNs) with which to identify any length of highway or road in England and Wales. Set up initially to improve highway maintenance, by the New Roads and Street Works Act, the NSG enables Utility companies and local councils to coordinate and know where and when to dig their holes. Under legislation, each highway authority is required to create and maintain its own local street gazetteer (LSG) and associated street data (ASD). This is then compiled into the only master index built to British Standard BS7666, for access by others via the NSG online hub. The process is managed by Intelligent Addressing on behalf of local government.
The Highway Authorities' data contains a wealth of useful information including road length, junctions, road centre lines, and a mass of associated street data (ASD) such as traffic sensitive streets, special engineering difficulties, protected streets and environmentally sensitive areas. Now that every Street Authority is providing regular updates the NSG is consolidating its place as the de facto dataset underpinning the national street infrastructure.

Notes to Editors
Intelligent Addressing is a specialist private sector consultancy (an SME) employing recognised experts in addressing. It was originally set up to help develop the National Land and Property Gazetteer (NLPG) on behalf of local government and now manages the NLPG and NSG central data hubs under the terms of the Mapping Services Agreement (MSA) with local government.
NSG
Required under the New Roads and Street Works Act, the National Street Gazetteer (NSG) is a comprehensive list of over 1 million named and un-named streets, footpaths and thoroughfares, the definitive source for anyone with an interest in streets and their usage. There are over 300 organisations, utilities such as gas, water and electricity, BT, plus cable and communications companies, named as âStatutory Undertakers' approved by the Department of Transport to download this data, which conforms to the BS7666:1-2000 Standard.
