Abstract

Pedestrian navigation is a complex function of humandynamics, a desired destination, and the presence of obstacles.People cannot stop and start instantaneously and theirturning abilities are influenced by kinematic and dynamicalconstraints. A realistic model of human walking pathsis an important development for entertainment applicationsand many classes of simulations. We present a novel behavioralmodel of path planning that extends previous modelsthrough its significant use of pedestrian performance statisticsthat were obtained during a suite of experiments. We developan original interpretation of quantitative metrics formeasuring a model's accuracy, and use it to compare ourpath planning approach to a popular contemporary method.Results indicate that this new path planning model better fitsnatural human behavior than previous models.
