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.
Highlights
As a main component of modern transportation, urban rail transit conforms with the principle of sustainable development and has advantages of large capacity, high speed, energy saving, low pollution, convenient, and comfortable [1, 2]
Task. e selected study site should have representativeness for the complex rail transit stations (CRTSs). e existing emergency simulation studies emphasis on crowded passengers, while this paper mainly focuses on the complex structure characteristic of the rail transit station
Rail transit stations with a multifloor structure integrated in 3D space have become greatly populated spaces. e passenger flow volumes of many stations are reaching or even exceeding their designed longterm maximum capacity
Summary
As a main component of modern transportation, urban rail transit conforms with the principle of sustainable development and has advantages of large capacity, high speed, energy saving, low pollution, convenient, and comfortable [1, 2]. In China, metro and light rail are two major categories of urban rail transit, and over 5761 km of urban rail transit are in operation in 35 cities, ranking the rst in the world [5]. E passenger ow volumes are constantly increasing and many rail transit stations have reached, or even exceeded, their designed long-term maximum passenger ow volume [6]. In 2018, the urban rail transit passenger ow volume reached to 21.07 billion in China, with an increase of 2.59 billion (14%) compared to the previous year. E average daily passenger ow volume of Beijing and Shanghai rail transit are 10.54 million and 10.172 million, respectively. In October 2018, the daily passenger volume of Renminguangchang station in Shanghai reached to 0.76 million, which is the maximal value in the station passenger volume record [7]
