Speed Limits
Optional designation that provides information about the speed limit applicable for the street. Only speed limits (signed or as per the legal order) over 40mph are recorded as standard with some LHAs providing 30mph speed limits as well. This data is intended to be used for planning of traffic management and works safety measures. This code is not used in Scotland.

Structures
For England and Wales, this is an optional designation used by asset owners to identify the existence of a structure that has not been designated as an SED. In cases where this identifies a Bridge, Works Promoters should regard it as a reminder that under Section 88 they must consult the Bridge Authority prior to serving Notices. For Scotland, this includes over-bridges and under-bridges as well as other structures including retaining walls, gantries, pipelines and cellars.
Traffic Calming Features
Traffic Calming Features include islands, build-outs, cushions, raised tables etc. This code is not used in England and Wales.
Traffic Sensitive Side Road When Temp Traffic Control is Employed
A traffic sensitivity designation applied to the first 50m (or complete length, whichever is shorter) of an adjoining street that has a junction with that traffic sensitive street. This code is used where road works on the adjoining street could cause delays on the traffic sensitive route. This code is not used in England and Wales.
Transport Authority Critical Apparatus
Optional designation that provides details of transport authority apparatus critical to operations of that authority which if damaged or if interrupted could disrupt or temporarily stop services (for example, HV cables to a rail network). This code is not used in Scotland.
Unusual Traffic Layout

Made Sealed
A constructed surface, commonly mineral based, that consists of a solid material that is bonded (i.e. is not loose) such as asphalt or concrete.
Made Unknown

Also used to describe surfaces that are bonded but have been employed as a mesh/grid or similar form; to allow vegetation to grow and water to drain through the surface.
Unmade
A surface that has not been constructed but has evolved through use by pedestrians, cyclists, horses being ridden or motorised vehicles and where the use has removed or minimised the natural vegetation and fully or partly exposed the underlying mineral surface and/or mud.
