Abstract

The architectural design of doors, gates and corridors can significantly contribute to crowd safety. However, the literature has yet to articulate our knowledge in crowd mobility. One potential approach is to look at the similarities between pedestrian and vehicle route choice behaviors while utilizing the theories and knowledge well accumulated in vehicle route choice research. To this end, a Cellular Automata model, consisting of a grid network of nodes/links to represent pedestrian movements, was developed. The rules of the movements are made based on principles consolidated in transportation, namely wardropian principles. The behavior of pedestrians under panic condition was modeled as a movement function associated with the corresponding link or direction, similar to vehicle delay function. A pedestrian assignment model (similar to traffic assignment) was then carried out. In order to evaluate the model, a case study of pedestrians evacuating via a narrow corridor and an exit door was introduced and studied numerically. Using the concept of the Braess Paradox, different architectural configurations for the corridor were analyzed to test their ability to facilitate greater rates of egress. Results were consistent with previous studies reported in the literature in which a funnel-shaped corridor can process a higher rate of pedestrians under crowded conditions. The proposed methodology has the advantage of being easily integrated and implemented into transport planning applications.
