Buckinghamshire Highways Asset Management Strategy 2021

Last updated: 4 February 2022

Inventory of highway assets

To effectively and efficiently manage the highway asset, a high level of understanding is necessary to enable fully informed management decisions to be made.

Buckinghamshire Highways (BH) will continue to maintain a register of all important highway assets that are held electronically in the AMIS. They are spatially located and referenced to the relevant street in the network.

Each asset has a range of attributes held depending on their operational requirements. The inventory contains sufficient data to allow reporting of the annual Whole of Government Accounts (WGA) valuation of the transport assets ensuring compliance with the requirements of the Code of Practice on Local Authority Transport Infrastructure Assets. BH will identify additional data needs through operational reviews and the requirements for the annual WGA valuation.

The current Asset Data Management Plan (ADMP) records the assets, their associated attributes and describes the update protocols in place to keep the inventory current. The register will continue to be updated regularly recording when assets are installed, removed or repaired.

The following Highway Infrastructure Asset groups are held in the AMIS:
