Dear Department for Transport,

I note that the Project announced by DfT on 25 Feb 15 by the Transport Minster goes live on 16th November, this is a very welcome and long overdue initiative.
The project stated it “has the potential to transform how all levels of government maintain and improve roads”

Please provide the documentation that will illustrate how the users of the maps will be able differentiation between:

A: Publicly maintainable highways
B: Privately maintained streets with unrestricted public access
C: Totally private streets but accessible for delivery purposes etc

Also please provide a list of Highway Authorities that have fully complied with 1-6 below in the data submitted to Ordnance Survey.


I understand the highway and street data is defined by 1991 NRSWA and mainly extracted from the Local Street Gazetteers /Street Works Registers (LSG/SWR) provided by Highway Authorities which they were required to set up under the Street Works (Registers, Notices, Directions and designations) (England) Regulations 2007 section 4(5) which states the register should include:

1. Every street for which the local highway authority are the street authority.
2. Every street which is prospectively maintainable highway.
3. Every street, of which the local highway authority are aware, which is a highway but for which they are not the street authority.

Note the Data entry Convention for Street Gazetteers states:

3.1.2 The LSG is a localised subset or constituent part of the National Street Gazetteer. The LSG is essentially a geographic register (gazetteer) of all streets within a LHA area. Each LSG shall record a register of all streets within the relevant geographic area regardless of maintenance or responsibility. It is recommended that public rights of way (PROW) and footpaths be entered into an LSG as street records.

Note also the BS7666 street definition

6.1.2 BS 7666-1:2006 defines a street as a way or thoroughfare providing a right of passage on foot, by cycle or by motor vehicle, or access to more than one property. It also positively excludes as definable streets rivers, waterways, railways and drives to a single property.

So that adds :

4. All streets serving more than 2 houses to be shown.
5. Privately maintained streets with public access to be shown.

I addition your Code of Practice for Streetworks (https://www.gov.uk/government/uploads/sy...) states:

6. The LSG/SWR should be accessible by the public.

Yours faithfully,

Thomas Evan Davis
