Value-in-use sustainability factor as a driver for asset management of road transport infrastructure

Abstract: Infrastructure is critical in supporting economic security and societal wellbeing. A sound road network, for instance, is an essential part of any country’s socio-economic fabric. However, the development of sustainable road infrastructure has been largely driven by environmental requirements as well as economic necessity. The experiences and satisfaction of users and the consequent value ascribed to the usage of road infrastructure have not been accorded reasonable attention. The current study examines the concept of value attributable to road infrastructure through its usage. A review of related literature was conducted using articles from journals, conference proceedings and from databases including Google, Taylor and Francis, ASCE Library, and Science Direct. Synthesis was done using thematic analysis. The study found that value is attributable to the experience of users and this depends on the condition of roads. Hence, maintenance of roads is paramount to sustain value. A conceptual model for value-in-use sustainability of roads was developed. The study recommends that more attention should be given to the experience of users while making use of the roads, as opposed to the monetary value of the roads only. Moreover, consideration of users’ experience will invariably drive demand for travel and bring about increased monetary returns. Therefore, the study highlights the import of the value-in-use concept, and creates more awareness about the conditions that invariably contribute to this value and thus transport managers and policy makers need prioritise asset maintenance and management even during planning
