Investment planning for ancillary assets

摘要

A research paper arising from work at University of Auckland describes the application of a stochastic based lifecycle planning tool, previously utilised for the strategic assessment of pavement maintenance funding and policy decisions, to ancillary pavement assets such as road markings and safety barriers. The stochastic approach recognises the fact that not all assets of a particular type will deteriorate at the same rate, or in a strictly deterministic manner. An understanding of current asset condition and future asset performance is lacking in most authorities for their ancillary pavement assets has become important as funding becomes tighter. The paper describes how condition assessment, as opposed to exception reporting, has been included in the detailed inspection program for Trunk Roads in Scotland. The application of the analytical tool in Transport Scotland is demonstrated and lessons learned are reported.
