Urban rail transit passenger flow distribution has a very important reference value for urban rail transit operation and management. Most of the current research focuses on static passenger flow distribution, and there are few studies on passenger flow allocation considering dynamic passenger flow demand changes. Therefore, this paper focuses on considering dynamic passenger flow. The problem of passenger flow distribution under the change of passenger flow demand. This paper first analyzes the time and space distribution characteristics of passenger travel demand, uses the 4-parameter Logistic function to fit the cumulative passenger flow curve segmentally, deduces the calculation formula of passenger flow demand at each station in any time period, and divides passenger travel into smooth state and the generalized travel cost of passengers is calculated based on the congestion state, combined with the logit passenger flow distribution model, the travel cost is dynamically revised and a solution algorithm is designed to achieve dynamic passenger flow distribution. Finally, the feasibility and effectiveness of the model and algorithm are analyzed and verified by constructing the urban rail transit network, and the passenger flow distribution under the dynamic passenger flow demand is realized.
