Pedestrian dynamics models the walking movement of individuals in a crowd.It has recently been used in the analysis of procedures to reduce the risk of disease spread in airplanes, relying on the SPED model.This is a social force model inspired by molecular dynamics; pedestrians are treated as point particles, and their trajectories are determined in a simulation.A parameter sweep is performed to address uncertainties in human behavior, which requires a large number of simulations.The SPED model's slow speed is a bottleneck to performing a large parameter sweep.This is a severe impediment to delivering real-time results, which are often required in the course of decision meetings, especially during emergencies.We propose a new model, called CALM, to remove this limitation.It is designed to simulate a crowd's movement in constrained linear passageways, such as inside an aircraft.We show that CALM yields realistic results while improving performance by two orders of magnitude over the SPED model. IntroducionPedestrian dynamics deals with modeling the movement of individuals, often as a part of a crowd.Its has been used in a wide variety of applications, from panic simulation and crowd behavior analysis [1][2][3][4][5][6][7] to diseases-spread modeling and robotics [6,[8][9][10][11][12][13].The most popular models for the simulation of pedestrian dynamics are social force models [14].Two sets of forces determine the movement of each person in these models.Propulsive forces tend ...
