A Probabilistic Model for Metro Boarding and the Related Parameter Calibration
This paper studies boarding probabilities of metro passengers at plat-forms.Under several reasonable assumptions,we prove a stochastic queueing model for passengers'boarding probabilities,which extends the deterministic queueing model(first-come-first-serve principle)in the research of Grube,et al.(2011)and Mo,et al.(2020).We present a simplified version of the stochastic queueing model that reduces to the deterministic queueing model when the parameter of the version is set to be zero.Based on the stochastic model,we construct a passenger flow simulation on a typical route.With the train schedule,passengers'tap-in times,and walking time distributions being inputs,the simulation yields each passenger's movement and tap-out time as outputs.Combining real data and simulation outputs,we provide a parameter calibration method.Real data analysis on Changping line of Beijing Metro illustrates advantages of the proposed stochastic model over the existing deterministic model.
