| Outline of Final Research Achievements |
In Japan, large-scale renewal projects are underway to address the growing number of aging road facilities. This study focuses on large-scale renewal projects of high-graded trunk roads, and develops the following two methodologies: First, a selection method that optimizes the objective function considering the cost to users such as traffic congestion and detours and the construction cost; second, a construction schedule optimization method that minimizes the cost to users such as traffic congestion and detours during the project period in multiple construction sections

大規模更新工事に伴う高規格道路の規制は道路ネットワーク利用者への影響が大きく，規制による利用者の行動予測を踏まえた戦略的な計画が求められる．本研究で提案した2つの手法はいずれも道路ネットワーク中の道路区間が一時期車線規制や通行止めとなる条件のもとで，利用者の通行パターンの予測を踏まえてその施工方法やスケジュールを最適化する方法論を提供したものである．これらの手法は大規模更新工事に適用できるだけでなく，土砂災害の復旧工事などの災害対応事業にも応用が可能であり，応用可能性は小さくない．
