Network congestion evolution law of urban rail transit based on network passenger flow mode
摘要
Abstract
To describe the passenger load state and the congestion evolution law,the concept and physical charactersfics of the network passenger flow mode are presented based on the concept of the passenger flow gradient,including the free mode,the congestion mode and the congestion dissipation mode.The calculation formula of the passenger flow field strength is used to estimate the alighting ratio.The passenger load index of the platform and the passenger load index of the segment are chosen as the key parameters of the point congestion,and the values of the network passenger flow mode are calculated.The key parameters of passenger flow exchange under the condition of network operation are proposed,and the dynamic evolution model of the passenger flow based on cellular automata is established to study the dynamic propagation and evolution law of the network passenger flow and describe the evolution mechanism of the group behavior of the network passenger flow.Taking part of Beijing subway network as an example,based on the actual survey data of the passenger flow,the network mode value at different times are simulated by MATLAB through adjusting the boarding ratio.The results show that different modes of the network passenger flow are presented at different time and therefore the physical characteristics are verified.关键词
