Abstract

Abstract: With the frequent occurrence of emergencies, how to evacuate dense pedestrians safely from indoor space with limited export is the key and difficult point of emergency evacuation research. Taking a university auditorium as an example to simulate through Anylogic, and the degree of consciousness is introduced to comprehensively reflect the safety education, safety training and familiarity of pedestrians and the expected speed of pedestrians in the primary social force model is improved. To solve the problem of uneven utilization of exports in multi-exit indoor, optimization plans including partition guidance and change the structure of exports are proposed. Simulation results show that the degree of consciousness can increase the expected speed of pedestrians and effectively reduce the evacuation time. Partition guidance, reasonable setting of exit width and exit interval can realize reasonable crowd diversion, reduce exit congestion, and effectively solve the problem of uneven utilization of exports.

Key words: social force model, anylogic, multi-exit, emergency evacuation simulation
