This goes in parallel to his research into introducing a dynamic agent model that derives aggregate spatial analysis from the visual affordances of the built environment.
Based on the principles of Turner's theory on Embodied space, his agent model proves to correlate well with natural movement behavior in architectural and urban environments.
[1] Alasdair is a computer scientist whose interests were focused on the interface between the domain of architecture and urban design and the underlying systems that comprise their socio-physical dimensions.
Alasdair’s work on spatial analysis constitutes the foundation of the agent model and supports research in space syntax theory.
[5] Space syntax theory was based on a graph-based representation of the spatial network in buildings and cities and what this implies in terms of the social logic of movement and occupation.
Together with Alan Penn, David O'Sullivan and Maria Doxa, Alasdair has introduced to visibility graph analysis (VGA).
Segment analysis was seen by Bill Hillier and Shinichi Iida to have some explanatory power by considering angular and metric graph properties of street networks and their psychological effects.
