| 摘要： | Managing an aging infrastructure under budget limitations is becoming a critical issue in many countries. A model system for supporting the process of road infrastructure management is presented. The system provides information on expected road performance in terms of pavement deterioration and need for repair. Also, the direct impacts on the users of the facility and indirect impacts on the regional economy are quantified and given at each performance level. The system is supported by a geographic information system as a tool to facilitate decision making. A case study is carried out using the developed system to analyze the performance of a selected road network under different budget levels. It is shown how losses incurred by users and the regional economy vastly exceed savings from road budget reduction. Therefore, the importance of applying such a system to quantify direct and indirect impacts of road performance is highlighted throughout this analysis. |
