9.1.1
This section provides background, data entry conventions and guidance as to how the Street state and surface for each Street and Highway Dedication Record must be maintained in the LSG to comply with the implementation of this reference manual. There is a certain degree of interaction between the LSG and the LLPG which is described in the Street state and surface Sections 9.3.2 and Section 9.3.3.
9.1.2
Following the release of DTF8.1, a new type 17 Highway Dedication Record was introduced. This replaced the link to a USRN with a link to each ESU for that section of Highway.
9.1.3
The code and definitions listed in this section contain more codes than the BS7666-1:2006 classifications for Street STATE, STREET_SURFACE and HIGHWAY_DEDICATION_CODE. The extra codes are required to accommodate legislation and inconsistencies with real world objects and scenarios.
