Feature Hierarchy

Within the UKPMS Automatic Pass, in the application of the various Rules and Parameters, extensive use is made of the Road and Footway Hierarchies that are defined in the Highway Maintenance Code of Practice to weight defects and suggested treatments and priorities according to the importance and level of usage of a particular section.

There are two options for the definition of Hierarchies within UKPMS. The carriageway or footway hierarchy can either be set for the whole section or, if item inventory has been collected, can be recorded at chainage, feature and xsp level for each inventory item. This allows, for example, account to be taken of a short length of heavily used footway with a section to be taken account of.
