Abstract: In this paper a DTA model with two components is described: a user equilibrium (UE) model and an en-route model. The UE model is called MARPLE (Model for Assignment and Regional Policy Evaluation) that uses an iterative process to achieve equilibrium (deterministic or stochastic) (Taale et al., 2004). In each iteration a network loading model is used to determine travel times. MARPLE en-route is developed based on the MARPLE model, which runs one-shot simulation starting with the equilibrium assignment results. It updates the path sets and path costs after each evaluation interval during the simulation. Travellers will update their path choice according to the instantaneous path costs at the end of each interval using some heuristic rules. A systematic framework for the robustness study of road networks is built up by combining both DTA approaches, in which the results of UE approach are used as references and en-route approach is used to simulate the network response for non-recurre nt and short-term disturbances. The results for a hypothetical network show that for evaluating the network performance after such disturbances, the en-route assignment approach based on UE assignment results shows its capability and advantages in appropriately representing dynamic drivers’ route choice behaviour when facing unfamiliar or unexpected situations on the route.
