ABSTRACT: Optimal evacuation strategies for areas under threat of flooding have to be studied by adopting scientific knowledge from transport engineering. Theoretically speaking full control over departure times, destinations and routes of people will be ideal. In practice the level of control is restricted. The context of preventive evacuation of dike-ring areas is described in this paper. A framework for modelling evacuations is presented. Practical constraints determine the actual outcome of the evacuation. Therefore, several methods are presented, which can assist practitioners in designing evacuation plans. Practical, simple and feasible traffic management solutions are deduced from an optimal solution where there is complete and dynamic control of the destination and routes of evacuees. A static quick-scan is developed as an alternative for timeconsuming dynamic model runs.A case study for the dike-ring area of Flevoland, The Netherlands is presented, where several of the methods are demonstrated.
