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)
This paper reports on the development of a multi-agent cellular automata model of pedestrian movement and decision making within the built environment. The approach will lead to a system that may serve as a tool in the design process to better understand how a design will influence user behaviour.
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)
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)
Recently hazard models have become increasingly popular in transportation research for modeling duration processes of various kinds. The application of hazard models is extended to the field of activity scheduling to account for the continuous nature of the decision-making process underlying activity performance. A competing risk hazard mod~l of the… (More)
It is increasingly recognised that land use change processes are the outcome of decisions made by individual actors, such as land owners, authorities, firms and households. In order to improve the theoretical basis of land use modelling and to represent land use chnages in a behaviourally more realistic way, we are developing PUMA (Predicting Urbanisation… (More)
