Movement Characteristics

To propose method that can optimize the movement efficiency of passengers in the railway station and then guarantee the personal security under emergency case, we did experimental and modeling research on the movement behavior and characteristics of the passengers in a railway station. Observation experiments were conducted to analyze the process of passengers catching trains and leaving the station, through which, the phenomena of lane changing and dislocation were found in a straight channel, and seven categories of baggage were also identified in the crowd. Analysis shows that personal speed would rise as the increasing size of the baggage. A modified lattice gas model focus on the passengers carrying baggage was further built to study passengers movement characteristics. Using this model, the effect of pause probability of passengers and the effect of channel width on movement efficiency were analyzed, according to which, a management strategy to promote the flow rate of crowd in railway station was proposed. This study may be useful to study on evacuation of the railway station, control of the passengers and formulate pre-proposal on emergency evacuation.

The field investigation of the human evacuation behavior of young people under time pressure in campus is conducted in Northeastern University of Shenyang. Based on the analysis of the observation of human evacuation behavior characteristics, scenarios of human evacuation in academic building under different evacuation management strategy are simulated and compared by FDS+Evac. The analysis results show that the crowd flow coefficient will be increasing under time pressure. The congestion of the crowd in academic building can be alleviated effectively on the base of batches evacuation management. The Real Safety Evacuation Time (RSET) can be reduced if the layout of exits is designed felicitously. Therefore, emergency drill such as fire drill is suggested to proceed periodically and regularly so that human can have opportunity to experience emergent and hazard surroundings to improve their ability of evacuation in emergency.

Extensive efforts have been made in pedestrian evacuation of urban rail transit systems, since there has emerged an increasing number of congestion problems. However, few studies focus on the comprehensive urban rail transit hubs. As a comprehensive interchange hub integrating urban railway and intercity railway lines, Beijing West Railway Station was taken as a case study object. The pedestrian evacuation characteristics were analysed first. Then, a social force-based simulation model of Beijing West Railway Station was constructed in PTV Viswalk. The model was applied to visually display a real evacuation process and help identify evacuation bottlenecks. The results showed that the risk points at different facilities had various causes and features. Furthermore, the simulation model could also be used to evaluate the effectiveness of different optimization measures as long as certain model parameters were changed beforehand.

Lattice gas automaton is a mathematical model that is used to simulate the horizontal uniform evacuation behaviour of a group. However, extended lattice gas automata model is proposed to examine marine evacuation behaviour, which is subject to deck heeling. The application of distance accumulation algorithm and the conversion probability mostly make the extended model, while the approach deals with the most complicated ship evacuation. Moreover, the suggested model is expected to enhance the safety and efficiency of evacuation. The distance accumulation lattice gas automata model considers multiple movement behaviours, flow density, deck heeling, counterflow, and congestion. Movement behaviour will be severely affected in deck heeling process where people may walk normally, walk while bent over, or crawl. To verify the proposed model, 11 test scenarios and several emergency evacuation scenarios are demonstrated. The simulation results explain the validity of another experimental model. The number of people in counterflow, deck heeling, and difference in movement have a direct effect on evacuation, which is as discussed in results. This research article provides a brief study on ship design and crew response behaviour in case of mishap/accident.

Safe Zones

Railway stations are usually considered to be one of the main gathering centers of the city; thus, in the event of any incident, there will be significant casualties. The purpose of this study is to simulate strategies for reducing the evacuation time of the railway station in the event of fire using a safe zone approach with simulation software. To reduce the evacuation time, 18 scenarios were introduced and simulated according to (1) number of gates and exit doors, (2) width of the gates, (3) obstacles, (4) priority of the exit doors, and (5) safe zone. The results show that the best evacuation time occurs by increasing the number of exit doors from two to four and considering a safe zone simultaneously; the evacuation time is reduced by 7 min and 19 s. Using safe zones for emergency evacuation has a significant role in reducing evacuation time and improving service levels. Interestingly, the removal of gates and obstacles would increase the evacuation time of passengers. The proposed model could be used for renovating existing railway stations to decrease the consequences of accidents such as fire.

Abstract Under the background of Covid-19 sweeping the world, safe and reasonable passenger flow management strategy in subway stations is an effective means to prevent the spread of virus. Based on the social force model and the minimum cost model, the movement and path selection behavior of passengers in the subway station are modeled, and a strategy for passenger flow management to maintain a safe social distance is put forward. Take Qingdao Jinggangshan Road subway station of China as the simulation scene, the validity of the simulation model is verified by comparing the measured value and simulation value of the time required for passengers from getting off the train to the ticket gate. Simulation results indicate that controlling the time interval between incoming passengers at the entrance can effectively control the social distance between passengers and reduce the risk of epidemic infection. By comparing the evacuation process of passengers under different initial densities, it is found that the greater the initial density of passengers, the longer the passengers are at risk social distance. In the process of passenger emergency evacuation, the stairs/escalators and ticket gates are bottleneck areas with high concentration of passenger density, which should be strictly disinfected many times on the basis of strictly checking the health code of incoming passengers and controlling the arrival time interval. The simulation results of this paper verify the harmfulness of passenger emergency evacuation without protective measures, and provide theoretical support for the operation and management of subway station under the epidemic situation.

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.
