Stochastic Based Lifecycle Planning Tool for Ancillary Pavement Assets

This paper 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. Historically, relatively little effort has been expended on investment planning for ancillary assets, compared to the pavement and structures stock. While this is understandable, given the relative asset values, recent public spending cuts have highlighted the need to include all pavement assets in public spending reviews. Unfortunately, because of this historic precedence, an understanding of current asset condition and future asset performance is lacking in most authorities for their ancillary pavement assets. Transport Scotland, the agency responsible for the management of all Trunk Roads in Scotland, has addressed the former through the inclusion of condition assessment, as opposed to exception reporting, in their detailed inspection programme. A condition assessment manual has also been developed to assist inspectors in carrying out their assessments. Knowledge of asset performance will come with time, however, in the interim, expert engineering knowledge has been harnessed to populate the deterioration algorithms. The application of the analytical tool in Transport Scotland is demonstrated and lessons learned reported.
