摘要：

Evacuation assistants are expected to spread the escape route information and lead evacuees toward the exit as quickly as possible. Their leading behavior influences the evacuees' movement directly, which is confirmed to be a decisive factor of the evacuation efficiency. The transmission process of escape information and its function on the evacuees' movement are accurately presented by the proposed extended dynamic communication field model. For evacuation assistants and evacuees, their sensitivity parameter of static floor field (SFF), kSL, and kSe, are fully discussed. The simulation results indicate that the appropriate kSL is associated with the maximum kSe of evacuees. The optimal combinations of kSL and kSe were found to reach the highest evacuation efficiency. There also exists an optimal value for evacuation assistants' information transmission radius.

Abstract:

Evacuation assistants are expected to spread the escape route information and lead evacuees toward the exit as quickly as possible.

The transmission process of escape information and its function on the evacuees' movement are accurately presented by the proposed extended dynamic communication field model. For evacuation assistants and evacuees, their sensitivity parameter of static floor field (SFF), kSL, and kSe, are fully discussed. The simulation results indicate that the appropriate kSL is associated with the maximum kSe of evacuees. The optimal combinations of kSL and kSe were found to reach the highest evacuation efficiency. There also exists an optimal value for evacuation assistants' information transmission radius.
