“…Emergency evacuation was emphasized as an important task in building design [13,14]. Evacuation routes, exits, stairways, passages, and turnstiles in rail transit stations are recognized as key facilities that directly influence evacuation route plans [15]. A crowd-aware environment design tool was proposed to analyze the optimal crowd flow-density relationships between crowd and environment [16].…”

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.

“…Relationships between single direction pedestrian speed and density were studied based on regression analysis. The main models include cellular automata mode, lattice gas model [6,[12][13][14], and social force model [7,15,16]. The crowd was regarded as a self-organizing system with cellular automata, which was composed of many individuals moving in station facility network according to certain rules, movements, and decisions under normal and emergency condition.…”

This paper is aimed at crowding phenomenon in the subway. As passengers are inclined to choose the route with minimum disutility, we put forward a route choice model which is constructed to achieve minimum objective function of feasibility for the optimal solution. Meanwhile we set passenger volume threshold values according to capacity of facilities. In the case of actual capacity exceeding the threshold, the decision node of constrained route will be selected; computing procedure about searching decision points will be presented. Then we should set rational restrictions at the decision node of the minimum utility function route to prevent too many passengers' access to platform. Through certification, this series of methods can effectively ensure the safety of the station efficient operation. Hindawi Publishing Corporation

“…The weaving pedestrian show special characteristics during spatial constraint (limited internal space) and also during time constraint (rushing). Generally, the focus on pedestrian flow characteristic will help us in evaluating the pedestrian flow during different scenarios such as in panic situation [22][23][24]. Several methods were introduced, ranging from statistical updating to simulation exercise to measure the interactions between pedestrians.…”

An Increasing amount of literature is devoted to discuss about the pedestrian movement pattern in indoor or outdoor environment. A better understanding of human behavior is the key to plan and manage the pedestrian flow especially in a transit terminal. Pedestrians visiting a public space have different motivations and therefore may behave differently. In order to determine the pedestrian behavior, some parameters should be measured such as walking speed, spatial use and person counts. The planners have generated a need to understand the pedestrian movement which behavior could be represented in collective form. A comprehensive review of the existing method in looking at the influencing parameters of the pedestrian behavior to the routes choice and pedestrians flow in relation to the level of service (LOS) and interaction of pedestrian in rail transit terminal is still lacking. Therefore, this paper aims to review the pedestrian movement characteristic in a rail transit terminal. Considering the differences of space requirements among different types of pedestrians and owing to the diverse characteristics of their stature, behavior and surroundings, immediate action on planning the rail based infrastructure is needed.
