Abstract
Over time transport networks are expected to remain highly reliable to ensure that users can experience smooth travel under both normal and abnormal traffic conditions. To design a reliable transport network properly it is necessary to take into account users reactions to incidents which cause disruption in different parts of the network over time. In order to design a reliable network to deal with such time-varying events it is necessary to capture the user’s route choice behavior under degraded conditions with the time dimension explicitly considered. Furthermore, for practical reasons, it is imperative that any improvement scheme be possible to implement. Therefore in this paper we formulate a time-dependent reliable discrete network design problem where the user’s behavior in route choice is modeled through the game theoretic approach. The ability of this model to design the critical links over time is demonstrated through two numerical studies under different budgets.
