@inproceedings { , title = {Developing a transition probability matrix as a measure of road network maintenance effectiveness.}, abstract = {This paper presents a study that assesses the effectiveness of road network maintenance based on historical costs and road roughness progression. The study is intended to measure the effectiveness of routine maintenance and a combination of routine and periodic maintenance. The study analysis is based on a database developed from the State of Victoria consisting of 898 low volume sealed road sections. A new effectiveness measure is introduced based whether road sections remain in the same state condition or move to next worst condition based on a predefined roughness value. Analysis shows that under routine maintenance (without periodic maintenance), the probability of road sections remaining in the same condition exhibit a declining tendency from good to worst state of conditions in comparison with a result when the maintenance budget is spent on a combination of routine and periodic maintenance. Following this, a stochastic prediction model is developed by converting the results into transition probability matrices. These results demonstrate a new and important rationale for road authorities to optimize the selection of appropriate maintenance measures.}, conference = {90th Annual Meeting of the Transportation Research Board}, note = {Note: Monograph Title - TRB 90th Annual Meeting Compendium of Papers DVD Conference dates: 23rd-27th January 2011 School: trans\_res}, organization = {Washington, DC}, publicationstatus = {Published}, url = {http://researchrepository.napier.ac.uk/id/eprint/6162}, keyword = {388 Transportation; ground transportation, HE Transportation and Communications, Condition surveys, Low volume roads, Maintenance practices, Pavement maintenance, Roughness, Sealing compounds, Test sections}, year = {2024}, author = {Mandiartha, Putu and Duffield, Colin F and Thompson, Russell G and Wigan, Marcus} }
