摘要:	都市地區通常存在複雜的管線設施。隨著此地區逐漸增加的公路擴建或維護工程，在公路施工時，一個整合不同管線廠商之管線設施地圖便成為讓公路工程專案成功之重要因素。無論從技術面或管理面，整合所有管線廠商資料均為一高度困難的工作。過去研究顯示即使管線廠商願意將其管線資料輸出至由公路局維護的中央管線資料庫，從此資料庫讀出的管線位置資訊仍常與公路承包商現場所見之實際管線位置有所不同。此乃因同步化管線廠商資料庫至公路局中央資料庫需相當多時間與人力，造成管線廠商較不願頻繁地更新中央資料庫。其他一些外在事件如地震等亦會讓管線移動，使得無論管線廠商或中央管線資料庫皆須更新。另外，一旦公路工程有伴隨附近管線遷移計畫，公路承包商便需目前的管線位置與遷移後的管線資訊，綜合分析兩資訊後方能設計最佳公路施工計畫以避免日後可能的公路管線衝突。是故，良好的中央管線資料庫應能提供所有公路專案參與者簡潔的管線資料更新介面，簡化資料更新的流程，並收集目前與未來的管線資料。目前資料庫領域最先進的移動式物件資料庫技術為解決上述問題的可行方案之一。源自於軍事用數位戰場等技術，移動式物件資料庫可儲存隨著時間變化的物件資訊，並提供與時間相關的查詢介面，以動態屬性簡化資料同步程序。本研究旨在設計以移動式物件資料庫為基礎之中央管線資料庫，包括系統架構與資料整合介面。首先將對於目前管線資料庫所使用的地理資訊系統與其他工程圖說技術作一文獻回顧，並探討移動式物件資料庫在公路工程設計施工階段可扮演的角色，設計其系統架構與資料整合介面，並實作一雛型系統以驗證此技術的可行性。本研究擬以台北地區之管線資料為例，進行實例測試與分析，進而提出結論與建議。 ; As more and more highway construction projects are located in highly congested metro settings, integrated maps that can show the locations of all utility facilities installed by different utility owners play a leading role in successful completion of many such projects. Integration of all utility owners』 facility data for a highway project is a highly challenging task from many perspectives. Past research indicates that even if utility owners can export their data to a centralized database maintained by a highway administration, the utility position data retrieved from the database usually do not match the actual positions of the utility facilities highway contractors can see in the job sites. This is due to the fact that synchronizing the utility data between the highway administration』s database and utility owners』 takes considerable efforts, making frequent utility data update infeasible. Other external events such as earthquakes may also make the utility facilities sliding or moving. In addition, since highway contractors need not only current locations of the utility facilities but the future utility adjustment plans in order to accommodate potential conflicts, a flexible location update mechanism that can provide responsible parties with a simple interface to enter both current and future utility data is desired. One advanced database technique that has emerged as a main focus of many spatial-temporal information systems such as the digital battlefield in the military is to keep track of object locations over time and to support temporal queries about future locations of the objects. Called moving objects database (MOD), this technique aims to deal with geometries changing over time and to simplify the data update process through use of dynamic attributes, thereby having the potential for eliminating or reducing some of the associated challenges and complications. This research explores the system architecture and integration mechanism of applying MOD to utility data management for highway construction projects. Current techniques such as geographical information system (GIS) to implement utility data management is examined first, followed by literature review of other engineering data exchange techniques. This research also discusses the role MOD can play in providing the utility location information needed to support highway design and construction. The system architecture and data exchange interfaces are designed, and a prototype system is implemented. The prototype system utilizing the MOD technique incorporates the context-sensitive, time-oriented and location-aware data exchange and query interfaces so that its users can retrieve the complete location history of a given utility facility. Moreover, by having the utility location history available in the new MOD system, highway contractors can compare it with the location data from their field investigation of utility facilities in order to better understand possible utility interference with highway facilities. A scenario using hypothetical Taipei City』s pipeline data is discussed, followed by conclusions and recommendations for the research. ; 研究期間 9701 ~ 9707
