ABSTRACT

In the infrastructure management field, the centralized control-based framework is widely applied to the road network management problem to derive network-level intervention policies. However, the optimal network-level intervention policy by the centralized control-based framework is difficult to derive and apply because there is no efficient solution method. In this study, we propose a new framework for the road network management problem, a decentralized control-based framework, where the network is divided into multiple groups and the sub-manager of each group decides the group-level intervention policy according to the aggregated information of all groups. Particularly, we propose a method to decide the groups of links and the solution method for deriving decentralized control-based intervention policies for road networks. Numerical studies demonstrate that the proposed decentralized control-based intervention policy can reduce the life-cycle costs of the road network compared with existing intervention policies.
