Simulation Of Microscopic Pedestrian Flow Of High-speed Railroad Junction Station

ABSTRACT:High-speed railway system is an important ways to solve inter-city traffic problem, so the main content of harmony Traffic is the construction of fast, convenient, feature-rich, friendly high-speed railway transport system hubs. The collective human in the High-speed railroad junction station Hubs usually is the hidden danger of accidents. The crowding is more serious, the accident risk is higher, and it also leads to heavier casualties and loss. Under the background of crowded safety incident frequency, the paper's research goal has established the high-speed railroad transportation gathering and distribution simulation model of pedestrian flow officially, and has developed the simulation software, realizes the rail station hubs' service level in different gathering and distribution situation of pedestrian flow and seeks for the rail station hubs' bottleneck.The paper has established the high-speed railroad junction station microscopic gathering and distribution model of pedestrian flow, divides the pedestrian gathering and distribution model into pedestrian walking model, abstracting characters of the facilities, the reaching pedestrian flow three parts to study. Established model of moving passengers based on the social strength model, according to the pedestrian society strength model to abstract the facility, constructs the high-speed railroad junction station and Use Poisson distribution to study the reaching pedestrian flow.The paper bases on gathering and distribution model of pedestrian flow, this paper build software framework of simulation of the microscopic gathering and distribution of Pedestrian flow in the high-speed railroad junction station, with methodology of Object-Oriented, designing a common simulation framework Facilities establishment module,pedestrian flow establishment module and result output module. With the software framework, this paper establishes simulation system of the microscopic gathering and distribution of pedestrian flow in Beijing South station, through the gathering data analysis to simulate Beijing South station to seek for Beijing South station's service bottleneck...
