高雄市是台湾最大的工业城市和第二大人口密集的都会区，由于缺乏系统有效的路面养护策略，因此难以管理其不断增长的城市道路网络。为了帮助提供一个令人满意的基础设施，为公众用户，本研究采用了现代化的路面管理系统的基础上效用理论和整数规划，以提高高雄的路面维修实践的整体效率。本研究透过组织专家小组及举办一系列研讨会，建立高雄市本土化路面管理系统的指引与要求。本研究发展一个以路面品质指标IRI与交通量为主要标准之最佳化模式，以支援路面维修预算分配之决策过程。本研究以高雄市主干道为研究对象，以最大的总效用为原则，提出最佳的道路养护方案，以达到道路使用者的最大利益。效用理论机制允许简单的实施和快速集成的其他性能指标在未来。效用转换是一个定制的过程，满足特定的地方法规和要求，使优化模型更实用，更容易应用于路面养护方案。该模型为城市官员确定和优先考虑路面维护需求以及更有效的预算提供了可行和科学的解决方案。
Lacking a systematic and effective pavement maintenance strategy, Kaohsiung, the largest industrial city and second most populated metropolitan area in Taiwan, struggles to manage its ever-growing urban road network. To help deliver a satisfactory infrastructure facility for public users, this research incorporates a modern pavement management system based on utility theory and integer programming to improve the overall efficiency of Kaohsiung’s pavement maintenance practices. The current work establishes guidelines and requirements of a localized pavement management system of Kaohsiung by organizing an expert panel and conducting a series of seminars. This study develops an optimization model involving pavement quality index IRI and traffic volume as the main criteria to support the decision making process of allocating a pavement maintenance budget. Using Kaohsiung urban core roads as the test bed, this study delivers optimal maintenance programs with the greatest total utilities, which represents the maximum benefits to road users. The utility theory mechanism allows simple implementation and fast integration of other performance measures in the future. The utility conversion is a customized process meeting specific local regulations and requirements, making the optimization model more practical and easier to apply in the pavement maintenance program. This model provides a feasible and scientific solution for city officials to identify and prioritize pavement maintenance needs, as well as more effective budgeting.
