This article presents dynamical models of the pedestrian decision-making behavior within a building, especially a small airport terminal, in routine and emergency operations that integrate the socio-psychological dimension of this behavior. In particular, the models account for the delays induced by pedestrian psychological processes, such as perception, identification, decision making, and by social processes such as milling and or reaching a consensus. Further, timeliness, a most important motivator of human behavior and of its adjustment to the environment, determines the activity and activity station choices of an individual pedestrian over time. For simplicity, this article adopts a sequential and hierarchical decision-making structure that encompasses high- and low-level planners easily reformulated as a combined selection model for the both. Task and activity selections take place within the high-level planner. A stress function acts as a time-varying utility function of an individual task that forces an account of its very timeliness. At activity station selection, the low-level planner accounts for the anticipated dis-utilities of the travel time and the energy cost expenditures to each station. The models presented are purely theoretical in nature. Future studies will attempt their calibrations and validations.
