9.4.4.1 Indicator Fields
The Physical Obstruction indicator Field - HD_OBSTRUCTION, must be set to “1” when something physically obstructs a Street user from travelling along the Street from one end to the other. Some examples are; bollards (raising or fixed), gates, plant pots, raised bridge etc. The Highway Dedication can or cannot change at this obstruction point. Obstructions may also be natural such as coastal erosion or landslips.
9.4.4.2
Physical Obstructions can occur on any ESU or at the junction with another ESU (In this scenario the indicator Field - HD_OBSTRUCTION would need to be present for both ESUs). ESUs must not be split at points where the Physical Obstruction is temporary or moveable (for example: rising bollards).
9.4.4.3
Where the Highway is considered a Quiet Route, for shared use by walkers, cyclists, horse riders and other vehicles, the indicator Field - HD_QUIET_ROUTE must be set to “1”. Quiet Routes are usually identifiable by specific entry and exit signs.
9.4.4.4
Where the indicator Field - HD_PROW is set to “1” because the ESU is identified as being subject to a PRoW, the ESU must be cross-referenced to the relevant type 3 Street USRN with a prefix of “Y” to specify its classification reference. A PRoW Record (type 66) must be present.
9.4.4.5
Where the indicator Field - HD_NCR is set to “1” because the ESU is identified as being subject to a National Cycle Route, the ESU must be cross-referenced to the relevant type 3 Street USRN with a prefix of “NCR” to specify its classification reference. A PRoW Record (type 66) must be present where they are applicable to a PRoW.
