| 摘要: | 本次研究主要透過道路巡查車導入「鋪面狀況指標PCI」，以桃園市八德區為例，探討鋪面狀況指標PCI數值之實務應用。利用各路段之鋪面狀況指標PCI數值辦理預防性養護、專案列管及派工修復，並依鋪面破壞類型選擇對應之修復方式，由各路段之PCI數值協助承辦人員診斷及判斷鋪面狀況，並作為派工前路段之輔助、參考及判斷依據。
鋪面狀況指標PCI是評估鋪面整體狀況的數值指標，藉由道路巡查及巡檢作業中，蒐集路面之影像資料，進行影像資料處理及電腦自動化運算後，獲得路段鋪面狀況指標PCI數值。並由鋪面狀況PCI數值作為派工前之參考，針對鋪面破損部分選取適當修復方式，以提前預防交通意外及事故發生，並降低未來維護成本、提升道路品質及增加民眾市政有感度。
透過建立明確之道路養護基準及作業程序，可使道路巡查及巡檢機制、鋪面修復更明確且清楚，並藉由持續執行過程中的問題及可更精進之部分，透過PDCA（Plan-Do-Check-Action）管理方式，不斷執行、回饋、改善及應用，以持續執行、即時修正、回饋應用及反覆循環，以達到最佳化成果。
;This research aimed to explore the practical application of Pavement Condition Index (PCI) values through the use of a road inspection vehicle. Using Bade District in Taoyuan City as a case study, PCI values for each road section were utilized to: (1) implement preventive maintenance, manage special projects, and assign repair tasks; (2) select appropriate repair methods based on the type of pavement distress, while assisting personnel in diagnosing and evaluating pavement conditions; and (3) serve as a reference and decision-making tool prior to issuing work orders for the respective sections.
The Pavement Condition Index (PCI) is a numerical indicator used to assess the overall condition of pavement, derived from the collection of road surface image data, followed by image processing and computer-assisted automated calculations. PCI serves as a basis for assigning repair tasks, with appropriate repair methods selected according to the extent of pavement deterioration. This approach not only helps proactively prevent traffic accidents and pedestrian incidents but also effectively reduces future maintenance costs and resource consumption, enhances road quality, and improves public perception of municipal services.
The results indicated that establishing clear road maintenance standards and operational procedures contributes to a more precise and transparent framework for road inspection and pavement repair. Furthermore, issues identified during the implementation process can be effectively addressed through the PDCA (Plan-Do-Check-Act) management approach, which facilitates systematic execution, feedback integration, continuous improvement, and practical application. This methodology supports ongoing implementation, real-time adjustments, feedback-driven refinements, and iterative enhancements, ultimately leading to optimized outcomes and improved efficiency and quality in road maintenance operations. |
