Network modelling and Management under Exceptional Conditions

<p>This talk addresses the development of theory and models to explain, predict, and manage dynamic network transportation and traffic operations in case of exceptional events (e.g. incidents, adverse weather conditions, flooding, bushfires). The dynamics involve traveller responses, impacts of the event on infrastructure, the uncertain event dynamics, the spatio-temporal propagation of the event impacts, and the countermeasures (information, guidance, control). These are analysed in a dynamic game-theoretic setting considering three actors: network authorities, network users, and fate (the exceptional event). </p><p> We focus on travel behaviour and traffic operations in relation to the degrading infrastructure (roads, public transit networks, communication, etc.). The transportation system itself is characterised by a high degree of freedom and multitude of choice alternatives of its users and by the fact that the users’ reactions – in terms of driving behaviour, route choice, compliance to an evacuation plan, etc. – are an essential but also uncertain component of the system response. </p><p> During the talk, the newly developed model EVAQ will be introduced. We will explain the main characteristics of the model, and show its application to several case studies. Next to this, we will also show how the model can be used for the optimization of evacuation schemes using dedicated optimization algorithms. In doing so, we show that the efficiency of the evacuation can be improved drastically. </p>
