13.3.1 Use of Whole Road Indicator and Associated Fields
Many ASD Records do not apply to the whole length or the whole width of the Street. Some ASD Records only apply to the carriageway and not the footway and vice versa. The WHOLE_ROAD indicator and associated Fields provide details of which section of the Street the ASD Record applies to.
13.3.2
If WHOLE_ROAD = 0 (not WHOLE_ROAD) on an ASD Record, accurate coordinates and a description must be provided detailing the position that the Record applies to within the Street.
13.3.3
The WHOLE_ROAD indicator identifies whether the Record applies to the whole of the Street or only part of it. Some examples of when the WHOLE_ROAD indicator is used to do this are:
- In the case of ASD type 61 Records, (Interest Records) typically the LHA or the HA is interested in the WHOLE_ROAD but a Bridge Authority is interested only in that part of the Street which contains their bridge.
- In the case of Special Designations, it is unlikely that special engineering difficulties, structures, special surfaces etc. apply to the WHOLE_ROAD.
- In London, TfL and the London Boroughs have shared responsibilities for several Streets and the use of the WHOLE_ROAD indicator is more common.
- Sometimes, administrative boundaries run down the centre of the Street (see Figure 31) and the maintenance responsibility for the Street is split between two LHAs. For example, Authority A maintains the eastern footway only and Authority B maintains the carriageway and western footway. This is recorded independently against the separate USRNs in each LSG using the WHOLE_ROAD indicator.
- If reinstatement categories change along the length of the Street, the WHOLE_ROAD indicator provides details of which categories applied to which lengths of the carriageway or footway.
13.3.4 Conventions - Additional Street Location Text
This Field must be completed if WHOLE_ROAD = 0 is present in the DCA Street Update indicating that the Record is for only part of the Street.
13.3.5
This Field provides a description of the extent of the Street affected by the Record if that extent is only part of the Street. The following sections describe good practice on the completion of this Field.
13.3.6
The text must avoid the use of jargon and ambiguous abbreviations.
13.3.7
The content must be set out in a structured way.
13.3.8 Start and End Coordinates
These coordinates must be provided only if WHOLE_ROAD = 0. The purpose of the coordinates is to identify the start and end point of the extent of interest or asset.
13.3.9
Apply the following rules to start and end coordinates:
- Coordinates must be recorded with eight numerical figures including 2 decimal places (leading zeros are required in certain parts of south west England).
