Abstract

Despite the importance of vision in accurately modelling and assessing pedestrian behavior, simulation software packages do not typically enable users to evaluate the vision of people. This paper describes a high efficiency method for evaluating the visibility of environmental geometry in a 3D pedestrian micro-simulation and proposes a geometric definition for the cone of vision to be used in these evaluations. Finally, the paper will provide a set of demonstrations of this approach to pedestrian vision evaluation using the commercially available 3D crowd simulator MassMotion.
