Internet-based stated response survey for no-notice emergency evacuations

Abstract: Large-scale evacuations from major cities during no-notice events - such as chemical or radiological attacks, hazardous material spills, or earthquakes - have an obvious impact on large regions rather than on just the directly affected area. The scope of the impact includes the accommodation of emergency evacuation traffic throughout a very large area and the planning of resources to respond appropriately to the needs of the affected population. Compared to events with advance notice, such as evacuations based on hurricanes approaching an affected area, the response to no-notice events relies exclusively on pre-planning and general regional emergency preparedness. In this paper we present the design, methodology and results of a survey which was conducted in order to obtain empirical data on individuals' responses to no-notice evacuation which can be used to calibrate an evacuee behavior model for planning purposes. The results of the survey show that people are more likely to evacuate if they see...

The 1st International Workshop on Agent-based Mobility, Traffic and Transportation Models, Methodologies and Applications A flexible framework for developing integrated models of transportation systems using an agent-based approach

Abstract: Travel demand, traffic flow and land-use models are typically modeled in a decoupled way, i.e. each of the components is modeled separately assuming that parameters related to the other components are fixed. Moreover, the models are often developed by different groups for different contexts, requirements, etc. In this paper we present a prototype of a software framework which allows the user to develop an integrated simulation of a transportation system and also to link additional models to the new simulation in a standardized way. We use an agent-based approach as the basis of such a model. Integrated transportation system models allow model users to overcome the limitations of traditional aggregated, independent transportation models, particularly with respect to sensitivity to behavioral aspects of the travelers. Another requirement, which the software is to satisfy, is the interoperability of models developed in the new framework with legacy models. By interoperability we mean, that any component of the of the model can be interchanged by a legacy software and be used for the integrated simulation. This would allow disparate research groups working on modeling different aspects of a transportation model to plugnplay their models into the framework and test those as a part of an integrated model of an entire system, providing a benefit to researchers, modelers and institutional users of such models. c � 2012 Published by Elsevier Ltd.
