Abstract: Along with the rapidly increasing urban population，more and more researches focus on the pedestrians flow.However，the current domestic and international researches on pedestrians flow is mainly concentrated on pedestrians flow on walkways，few researchers study on the characteristics of pedestrians flow on stairways in some significant distributing centers.In this thesis，by the investigation to the characteristics of pedestrians flow on stairways in some main pedestrians distributing centers，such as the Shanghai Chifeng Road light orbit station，Shanghai People’s Square subway station and the Shanghai train station and so on，and on the basis of the investigation data above，free flow density and jam density of pedestrians flow on stairways are made certain.And the form of function about density-velocity and density-flow rate of pedestrians flow on stairways is confirmed，then fitting functions in term of investigation data and ensuring parameters by using software，such as Matlab，thus the functions of pedestrians flow in transfer stations are gained.By comparing vehicles flow to pedestrians flow on stairways，pedestrians flow on the walkways to pedestrians flow on stairways，the foreign related researches to this thesis’ research，the models of pedestrians flow on stairways are suitable for transfer stations in some big cities in china.It will offer references and directions for improving capacity of stairways，and organizing effectively pedestrians flow.
