Pedestrian Modelling and Circulation Diagrams in Three-dimensional Built Environment

The work presented in this paper is a continuation of previous research done by author on the development of computational techniques that allow the investigation of pedestrian movement behaviour in the built environment. Specifically, the work has been initiated by introducing a pedestrian modelling approach, which simulates pedestrian movement behaviour and generates circulation diagrams in two-dimensional built environment of urban areas and buildings, in different scales, degrees of complexity, as well as for different architectural design purposes. Current research attempts to move further by introducing ideas for the development of computer program towards its third-dimension. In order to achieve this, the paper will introduce the existing model giving an indication of its functional characteristics, rules and information. Then, suggestions for possible development towards the third-dimension will be demonstrated and discussed. The work aims to give emphasis on the creation of new objects, behavioural rules and information that can be applied in urban or architectural design problems in order to achieve pedestrian movement behaviour in three-dimensional built environment.
