Research And Implementation Of Pedestrian Traffic Simulation Based On Social Force Model In High-Speed Railway Comprehensive Passenger Hub

Comprehensive transportation hub,as one of the important distributed network nodes of passenger transport system, is place of the passenger distribution and transfer. By giving full play to the hub function can greatly improve the efficiency of pedestrian traffic. With the vigorous development and wide application of computer technology, through the use of computer simulation techniques to the quantitative study of the distribution law and the transfer efficiency of passenger transport hub can make evaluation and optimization on the hub planning result seasier. In order to accurately simulate the behavior of pedestrians in the integrated transport hub for passenger traffic, we need an accurate description of the pedestrian motion model, pedestrian path search and selection model, as well as pedestrian queuing model of pedestrian movement with in the transportation hub. The correct simulation model can ensure the accuracy of the simulation results in order to more accurately evaluate and optimize the structure and function of the comprehensive transportation and improve passenger transport hub in the run utility.(1) This paper selects social force model as pedestrian motion model, describes the parameters anddoes experimental calibration of the parameters of the social force model. This paper adds the perspective of factor g(θ) to improve the social force model.(2)The paper studies the pedestrian way search model, and put forward the pedestrian path planning model and path selection algorithm. In addition, the article studies the pedestrian traffic queuing model and put forward the following behavior algorithm of pedestrians in queue and the algorithm of ticketing services.(3) This paper designed and developed a comprehensive transportation pedestrian traffic simulation system. This system is divided into the simulation data management module, the simulation initialization module, a simulation control module and the simulation output module. The system uses of the present study of pedestrian traffic, and ultimately verify the simulation modelthrough the simulation display and analysis of simulation results.(4) This paper summarizes the evaluation and classification of this group and other literature and simulated the pedestrian transfer behavior of Beijing South Railway Station basement, and analyzed the simulation results, and evaluated and graded the hub of the Beijing South Railway Station basement structure and function.
