Switching Action Behavior Model in Crowd Behavior Simulator

Abstract

The switching action behavior model is proposed for the CBS-DE to describe a person who has to change his/her destination due to the space capacity limitation of the designated evacuation area. The change in the destination of a person is determined according to the motion of other persons in the perception domain during the defined switching action time. The switching action time is formulated in the so-called switching action function which is described by a convolution integral of the input and unit response functions. Subsequently, the potential for further applications of the CBS-DE with switching action behavior model is demonstrated on different conjectural scenarios of the evacuation in an attempt to simulate the evacuation process with a change in destination. In the present study, the focal interest is the performance of the switching action model by demonstrating a change in destination in the evacuation process.
