Modeling And System Of Pedestrian Flow In Rail Hubs

With rapid development of rail transportation and the network, the operation and efficiency of rail transportation hub have become increasingly concerned. People simulate passenger behavior in rail transportation hub to improve the efficiency of passenger mustering and evacuating by using computer simulation, it has become a trend. Flow generation is the basis of flow simulation, which determine the accuracy of simulation results, so the research on principle of flow generation is important. Based on the above background, and simulation software MTR-PedSIM independently developed by team, Paper research on flow generation model of rail transportation hub.Paper first introduces the development of rail transit hub, and summarize domestic and international research results of microscopic simulation and arrival law of rail transportation hub, and clarify the significance of the passenger flow generation model construction. Then describe the concept and type of rail transit hub clearly, and propose the three-stage method to analyze passenger flow in rail transportation hub. After that, For different types of rail transportation hub, analyze respectively the arrival law of the passengers, passenger flow time distribution and flow spatial distribution of the platform, systematically elaborate the passenger flow generation in the rail traffic hub.Based on the above analysis of theories and concepts, built passenger flow generation model of rail transportation hub, which contains three generation methods. These methods are based on train schedule production, based on regular passenger flow rule and based on passenger survey. Then respectively describe the input conditions of model and implementation algorithm for the different methods, after that, develop passenger flow generation system, and introduce the four main functions of the system.Finally, three methods have been proposed for model calibration, namely, index comparison, parameter comparison and curve fitting. Taking Beijing South Railway Station and Beijing subway Lama Temple station as examples, validation methods was used to analyzing the results of flow generation, the analysis proves the reliability of flow generation results and rationality of the model. Through these research, combined with passenger flow generation system, we can generate passenger flow of any kinds of rail traffic hub, and provide rich passenger flow for passenger flow simulation system.
