Information Service Frequency of Urban Rail Transit Based on Passenger Flow Dissipation Rate

The improvement of the quality of information services can speed up the dispersal of aggregated passenger flow. To alleviate the safety hazards of the outburst mass passenger flow gathering at a certain station, we took the information service frequency as the research object and the passenger flow dissipation rate as an index to study the best information service frequency interval that passengers can accept. Firstly, we analyzed the influencing factors of passenger flow dissipation rate from the perspective of subjective and objective and proposed a model of passenger flow dissipation rate. Then, a corresponding influence factor model was established to determine the influence factor and the corresponding frequency interval. Finally, the model solving impact factors and the passenger flow data of the Wukesong subway station were used to solve the model of passenger flow dissipation rate, combining the frequency interval under a single factor to determine the best information service frequency interval under the influence of multiple factors.
