本研究以某縣市重劃追加工程為案例，針對交叉路口施工排程問題進行探討，彙整各交叉路口工項之作業內容、施工先後順序、人力需求、現地施工條件及排程限制，並參考既有交通影響評估資料設定相關參數與權重。本研究建構整合施工時序、人力資源限制與交通影響考量之整數規劃模式，在滿足工項前置關係、工期需求及每日人力資源限制等條件下，透過數學最佳化方法求解，並將交通影響作為施工排程評估之重要參考依據，以尋求較符合實務限制且可降低施工路口交通衝擊之排程結果。研究成果可作為後續施工排程規劃、人力資源配置及降低施工路口交通影響之決策參考。;With the acceleration of urban development， local governments have actively promoted large-scale public infrastructure projects， such as railway underground projects and urban land consolidation. These projects often involve adjustments to existing access roads and major intersections. During construction， reduced road capacity may create traffic bottlenecks， increase vehicle delay， lower the Level of Service (LOS)， and raise traffic safety concerns. In addition， the construction industry has recently faced challenges such as labor shortages and limited resource availability， which have increased the complexity of construction scheduling. Under resource-constrained conditions， improper construction sequencing may not only cause project delays， but also intensify the negative impacts on surrounding traffic and the living quality of nearby residents. Therefore， balancing construction efficiency with the reduction of traffic impacts under limited resources has become an important issue in construction planning and management decision-making.
This study examines the intersection construction scheduling problem using a supplementary urban land consolidation project in a certain county/city as a case study. The work contents， construction sequence， manpower requirements， site conditions， and scheduling constraints of each intersection work item are compiled. Relevant parameters and weights are established with reference to the existing Traffic Impact Assessment data. This study develops an Integer Programming model that integrates construction sequencing， manpower resource constraints， and traffic impact considerations. Under the constraints of work-item precedence relationships， project duration requirements， and daily manpower limits， the model is solved through mathematical optimization. In this study， traffic impact is incorporated as an important evaluation reference for construction scheduling， with the aim of obtaining a schedule that satisfies practical constraints while reducing traffic disruptions at construction intersections. The results can serve as a decision-making reference for future construction scheduling， manpower resource allocation， and traffic impact mitigation at intersections.
