Analysis And Evaluation Of Passenger Flow Operation State In Urban Railway Transit Hub

The urban railway transit hub,which is the node in the rail transportation network, plays an important role as the support of the network effects and scale effect. Meanwhile,the passengers flow is centralized in the hub,where the bottleneck of the traffic supply and demand is.At present,research and evaluation on the hub layed particular emphasis on probing into the adaptability of facilities and evaluation of service level inside the station,but slightly paid attention to the states of the passengers' traffic flow.The thesis sets up an evaluation index system for the passenger flow state in railway transit hub,which is on the foundation of passenger traffic flow operation state. The study is useful for taking implement control and decision in right time in traffic management.The thesis,beginning with analyzing the characteristic of the passenger in hub, studies about the passenger's composition of age,sex,the luggage structure, coming&leaving characteristic and traffic characteristic of the passenger flow in urban railway transit hub.Combining with the characteristic of the passenger of urban railway transit hub,the thesis defines and divides the state of passenger's traffic flow from three aspects such as the stabilizing intensity,balanced intensity,smooth intensity;Then descripts and analyses the state of passenger's traffic flow by the nature and quantitative from the views of reacting type,reaching time interval,space distribution,pace and density; proposes an principle and method for passenger traffic flow state division in urban railway transit hub.On the basis of the understanding of the passenger traffic flow state in urban railway transit hub,combining with the applicability of entropy theory in appraising the respect of pedestrian's system,the thesis have set up the passenger traffic flow evaluation index system in urban railway transit hub,taking the stabilizing intensity, balanced intensity,smooth intensity as criterion.Drawing lessons from entropy theory, the thesis raises up six evaluation indexes such as the response type statistics entropy, the attribute constitution statistics entropy,arrival interval statistics entropy,the balance for space distribution,operational efficiency,the degree of saturation in space,etc. Consulting with existing comprehensive evaluation method and characteristic of evaluation index,the thesis proposes the "Three-Dimensional Cube Layer" evaluation method.Finally,taking Xizhimen station of Beijing as an example,the thesis appraise the passenger's traffic flow,and compare the evaluation result with the result of HCM2000 pedestrian service level evaluation,verifying the rationality and feasibility of the evaluation index system.At the same time,it is practical application of passenger traffic flow evaluation index system in urban railway transit hub.
