A simulation analysis for pedestrian flow management

Summary

An agent simulation test model for pedestrian flow has already been developed, but an experimental simulation that incorporates actual data about an accident has not been designed. In our research, we have reconstructed this accident by improving an existing test model. Based on the accident report and using data gained through spatial research we have revised a pedestrian flow simulator. Through a simulation analysis including rows of standing people and the confrontation of the ascent and descent flows, we have explored measures to prevent a pedestrian accident. The ASPF is to assess measures for managing pedestrian flows by focusing on the domino risk rather than a reconstruction of crowd collapse as in the overpass accident. The simulation results show that a two-way flow, combined with stationary people can trigger an accident even on an overpass that satisfies present design standards. Moreover, we have confirmed that even simple traffic regulations such as partitions can be an effective measure to prevent a pedestrian accident.
