The Nomad model: theory, developments and applications

This paper presents details of the developments of the Nomad model after being introduced more than 12 years ago. The model is derived from a normative theory of pedestrian behavior making it unique under microscopic models. Nomad has been successfully applied in several cases indicating that it fulfils requirements for accuracy, scope and computational efficiency. In this paper we introduce the components of the model by relating them with behavioral assumptions providing an explanatory character to Nomad. The link between the model and the pedestrian theory is the main contribution and could improve the development of pedestrian models in general. (C) 2014 The Authors. Published by Elsevier B.V.
