Identification of Single or Rolling Multiyear Work Programs for Road Network Preservation

抄録

Strategy and program analyses using option evaluation systems (OESs) such as HDM-4 have been powerfully used for exercising pavement management planning at the network level. Theoretically, there is no distinction between strategy analysis with dynamic sectioning (SDS) and program analysis, and the results of SDS analysis may be used directly to identify the most appropriate single or rolling multiyear work programs and contract packages for individual sections of a road network or sub-networks. However, techniques for doing such an analysis have not been well presented. Therefore, the objective of this paper is to provide a systematic procedure as a guideline for identifying single or rolling multiyear work programs under given budget constraints where the SDS is utilized. The presented procedure employs HDM-4 as an OES for the purpose of demonstration, but it is deemed to allow almost any OESs.
