This study aims at formulating and testing a model of store choice dynamics to measure the effects of consumer characteristics on consumer grocery store choice and switching behavior. A dynamic hazard model is estimated to obtain an understanding of the components influencing consumer purchase timing, store choice, and the competitive dynamics of retail(More)
This paper describes the first impressions of the development of a multi-agent system that can be used for visualising simulated pedestrian activity and behaviour to support the assessment of design performance. This system is based on cellular automata and agent technology. Agents represent objects or people with their own behaviour, moving over a(More)
We introduce the outline of a multi-agent model that can be used for visualizing simulated user behavior to support the assessment of design performance. We will consider various performance indicators of building environments, which are related to user reaction to design decisions. This system may serve as a media tool in the design process for a better(More)
In this paper we present a Decision Support System developed to assist urban planners and policy makers to simulate and analyse alternative urban layouts, land uses, and growth patterns. The core of the system is a modelling and simulation shell allowing the user to specify Constrained Cellular Automata models of urban and regional systems. Unlike(More)
Recent policy changes and methodological advances have led to new modeling approaches of increasing complexity in transportation research. Some of these approaches require new kinds of data. Moreover, the increasing complexity of these models often also implies that more detailed data are required, leading to increased demands on respondents. This paper(More)
Several activity-based transportation models are now becoming operational and are entering the stage of application for the modelling of travel demand. Some of these models use decision rules to support its decision making instead of principles of utility maximization. Decision rules can be derived from different modelling approaches. In a previous study,(More)
Virtual Reality-based user interfaces (VRUIs) are expected to bring about a revolution in computing. VR can potentially communicate large amounts of data in an easily understandable format. VR looks very promising, but it is still a very new interface technology for which very little application-oriented knowledge is available. As a basis for such a future(More)
