| 摘要: | 自103年桃園縣改制為桃園市後，道路養護成效提升被視為主要政策之一，隨著財政、預算（主計）等業務依法調整為桃園市政府轄管後，在有限預算內各區公所該如何有效運用資源，並使效益最大化成為重要課題。為此，本研究先參考日本道路鋪面養護排序模式，並以鋪現況面指標(Pavement Condition Index, PCI)觀念為基礎，接著彙整龍潭區都市計畫區內市區道路之道路巡查紀錄、維生管線挖掘申請及1999(市政信箱)通報等案件，客觀歸納出龍潭市區道路分級方法與鋪面破壞因子。
本研究擬定之道路分及與鋪面養護排序準則，分別以龍潭區公所現行之主觀經驗排序法及單一指標排序法之排序結果比對，對於市民經常使用之市區道路路段可獲得較佳之養護優先排序，而未列入排序之路段則可利用其他修補方式改善道路品質，因此歲修預算可較靈活運用，提升道路養護決策之精準度。
最後試將桃園市「桃園市道路養護管理執行計畫年度考評」考評項目與「前瞻基礎建設-城鄉建設-提升道路品質計畫」操作策略聯結，本研究之「市區道路分級與鋪面養護排序準則」對大部分之重點項目有所呼應。
關鍵詞:市區道路、道路分級制度、鋪面養護排序、PCI;Since the restructuring of Taoyuan County to Taoyuan City in 2014, the improvement of road maintenance effectiveness is regarded as one of the main policies. Finance, budgetary and other businesses are under the jurisdiction of the Taoyuan City Government, how to effectively use resources and maximize the benefits of the district offices within a limited budget becomes an important issue.
This study refers to the Japanese road pavement maintenance sorting mode, and based on the concept of Pavement Condition Index (PCI), aggregate the surveying road records of urban roads in the urban planning area of Longtan District, mining critical infrastructure applications and reported cases from citizen hotline (mayor′s mailbox), objectively summarize the road classification method and pavement damage factor in Longtan City.
According to the grading method and the importance of each factor reference to the impact of the pavement, the corresponding weights are given, and a set of grading maintenance guidelines for the roads in Longtan City are drawn up.
The conservation guidelines developed in this study compares the sorting result of the current subjective experience ranking method with the single index ranking method of Longtan District Office, urban road sections frequently used by the public has higher conservation priority, sections not included in the sorting use other repair methods to improve road quality. Therefore, the budget can be used more flexibly and improve the accuracy of road maintenance decisions.
Finally, coupling the Taoyuan City "Taoyuan City Road Maintenance Management Execution Plan Annual Assessment" evaluation project with the "Foresight Infrastructure - Urban and Rural Construction - Improving Road Quality Project" Operation Strategy, the "Longtan Urban Road Graded Conservation Guidelines" of this study responds to most of the key projects, it can be used to improve road maintenance performance and strive for more subsidies.
Key words: Urban roads, road grading system, paving maintenance sorting, Pavement Condition Index. |
