Emergency Evacuation Simulation and Optimization for a Complex Rail Transit Station: A Perspective of Promoting Transportation Safety

Abstract

Rail transit stations with multifloor structures have been built in many cities to intensively utilize land resources and facilitate lives of community. However, being overcrowded with passengers results in high risks during daily operation. In response, this study conducted an emergency evacuation simulation and optimization in the three-dimensional (3D) space of “complex rail transit stations” (CRTSs). The aim of the paper is to provide a methodology to determine effective emergency evacuation strategies for CRTSs. The Lianglukou Rail Transit Station in Chongqing, China, was used as a case study and the AnyLogic simulation platform employed for simulating emergency evacuations. An emergency evacuation theoretical framework was established. The emergency evacuation strategies, including evacuation routes and evacuation times, were determined based on the theoretical demonstration. Simulation and optimization of emergency evacuation in the Lianglukou station were conducted. Accordingly, four main simulation results were obtained: (1) Escalators/stairs and turnstiles are key facilities in the evacuation; (2) Effective guidance for the evacuation is necessary in the public space of the station; (3) Passenger aggregation nodes should be guided for balanced evacuation; (4) Removing metal barriers is a useful evacuation optimization measure. The proposed research method and framework can be used by other CRTSs in the establishment of emergency evacuation strategies and effective optimization strategies to promote safety of transportation system. The research findings are beneficial to passengers in helping them provide valuable emergency evacuation guidance.

Towards simulation optimization of subway station considering refined passenger behaviors

“…Cheng et al [ 5 ] and Sun et al [ 6 ] believed that elevators and staircases are the most congestion area of subway station, which can relieve by setting guardrails. Xu et al [ 7 ] concluded that escalators and stairs was critical points for decongestion, while the removal of metal barriers was a useful decongestion solution. Wu et al [ 8 ] proposed the decongestion solutions that installing additional railings to disperse passenger flow and adding more ticket gates.…”

Optimization of Land Resource Information Management System Based on Internet of Things

“…At the same time, the construction level of our cities urgently needs to be more on a higher level, making the shortage of land resources and mineral resources present new challenges in the process of land resource management, so how to improve the speed of land and mineral resource use has become a key issue that urgently needs to be solved nowadays, and land resource management departments need to effectively combine information technology, land information management technology, and resource information management technology. Using the abovementioned technologies can improve the efficiency of land and mineral resource information management, and the influx of information technology has gradually become the direction of improvement in the development of land security management [2].…”
