A decision making framework for recommended maintenance of road segments

With the rapid development of global road transportation, countries worldwide have completed the construction of road networks. However, the ensuing challenge lies in the maintenance of existing roads. It is well-known that countries allocate limited budgets to road maintenance projects, and road management departments face difficulties in making scientifically informed maintenance decisions. Therefore, integrating various artificial intelligence decision-making techniques to thoroughly explore historical maintenance data and adapt them to the context of road maintenance scientific decision-making has become an urgent issue. This integration aims to provide road management departments with more scientific tools and evidence for decision-making. The framework proposed in this paper primarily addresses the following four issues: 1) predicting the pavement performance of various routes, 2) determining the prioritization of maintenance routes, 3) making maintenance decisions based on the evaluation of the effects of past maintenance, and considering comprehensive technical and management indicators, and 4) determining the prioritization of maintenance sections based on the maintenance effectiveness and recommended maintenance effectiveness. By tackling these four problems, the framework enables intelligent decision-making for the optimal maintenance plan and maintenance sections, taking into account limited funding and historical maintenance management experience.
