Description

Option evaluation systems (OESs) have been extensively used as an effective means to support decision-making on investment and management of road asset in both developed and developing countries over the last four decades. When carrying out the strategy analysis using OESs with dynamic sectioning (called SDS), a nationwide network is typically subdivided into several sub-networks due to administrative or technical needs. However, techniques for doing SDS in such a case have not been well developed. Therefore, the objective of the paper is to present a comprehensive procedure to carry out the SDS for a nationwide road network including sound trade-off analyses of all constituent sub-networks. Although the Highway Development and Management System (HDM-4) is used as an OES in the case study in this paper, the proposed procedure is general enough to allow almost any OESs.
