Study On Post-assessment System And Indexes For Urban Rail Transit Passenger Flow

With the rapid economic development, urban rail transit's construction is coming to the peak. But in the operating of rail transit,the non-equilibrium factor of passenger flow is more serious. At the present time, passenger volume are too many over the diode current capacity during the peak time, and in the peak absences is opposite. The difference between operation passenger and predicted passenger need to research. The result is to improve service quality of rail transit, bring into play a role in resolving traffic above-ground, supply convenience service for people.According to the meaning and characteristics of passenger flow,the paper constructed post-assessment system. It gives the definition of post-assessment passenger flow for urban rail transit.On the basis of this, it analyses deeply influencing factors of rail transit passenger flow, summaries the characteristics of rail transit based on the actual data of passenger flow. All of this provide the basis for construction of the post-assessment index system.Based on the organization of passenger flow and operation safety, in the view of practicability,the paper studied the way to assessment passenger flow. The post-assessment passenger flow system includes the content, methods, steps, the choice of time limit, data collection, index selection. The content is consist of passenger flow proportionality, passenger flow increasing, passenger flow development trend.According to the characteristics of passenger flow, the paper applies qualitative comparison and quantitative comparison and combines passenger flow forecast with passenger flow development trend to define time limit of post-assessment. Based on the PSR model, the paper constructed post-assessment index system of passenger flow.The system includes post-assessment index system of station passenger, line passenger, network passenger. This paper study on the post-assessment of passenger flow is in order to solve the existing dilemma for rail transit, and supply feasible advice for passenger flow forecast and operation of rail transit.Then,this paper takes the Beijing subway line 5 as an example to verify the post-assessment system and index of passenger flow. And it aims to the specific issue of line 5 to provide feasible suggestions for passenger flow forecast and operation.
