Abstract |
The road user cost in indirect costs as well as direct costs such as the inspection/diagnosis cost and the repair/reinforcement cost should be considered as one of the important items in the life-cycle cost-effective design and maintenance of the bridges. To estimate the road user cost, this paper formulates the road user cost as a sum of the user delay cost and the vehicle operating cost considering the detour effect. A numerical traffic simulation and a regression analysis are performed to develop a regression model due to a time delay. The proposed regression model is applied to the generation of the maintenance strategy based on the life-cycle cost and performance. and its effectiveness and applicability is investigated. The road user cost has a great influence on establishing the maintenance strategy. and the proposed regression model could be successfully utilized to estimate the road user cost of a bridge.
