Discussion on Road Infrastructure Management Practices

The objective of this study is to discuss and compare the practices of Road Infrastructure Asset Management System (RIAMS) adopted in different countries. This discussion mainly focuses on the pavement management system. Internationally, the RIAMS approach is moving from the condition-based towards the service-based approach focusing on the customer-driven priorities. This service-based approach needs to be balanced with the budget constraints, level of service and risk tolerance. The transportation agencies have not yet addressed the integrated land use and transportation modelling, the comparison of the relative advantages between capital and operating investments, the risk-based estimation, and the identification of a range of costs associated with the failure within the RIAMS. The transportation agencies should develop a performance-based RIAMS ensuring the serviceability, accountability, stewardship, long-term financial plans, and transparent investments. The RIAMS is still emerging and needs to incorporate the local mission, budget and other constraints within the scope of the local context.
