Research On Passenger Travel Choice And Path Generation For Urban Rail Transit Network Simulation

With the fast development of the Urban Rail Transit of China which gradually forms a multi-line network structure. The rail operations managers need to know the distribution of traffic on the network to organize, and the passenger travel path is the key to dynamic distribution. Simulation is an important tool for network operator to make decision. Individual oriented information generated passenger path is an important foundation to realize the passenger flow distribution deduction. Therefore, research on individual passenger path choice and generated is demand.This paper summarizes the main types of Urban Rail Transit simulation; conclude the simulation requirements under the network conditions. For mature Logit model, through the experimental data analysis the Logit model adaptability in individual path simulation. Propose combination of Logit model, to dig the individual passenger path choice rules using real operating data of urban rail transit system. Construct data based individual passenger path choice model, gives the solution to the problem of the individual passenger path choice for simulation.This paper constructs easy to express the rail transit network topology model, studies the passenger data survey method, the individual passenger path data matching deduction method. Realize the data preparation to construct the model. Based on it, this paper using passenger surveys to obtain passenger travel characteristics and willingness use the Bayesian network to calculate the main factors of passenger’s travel. Propose the way of modeling passenger travel path model, and use the classification and regression trees to build passenger travel path choice model, with the data of passengers credit card to learning and reasoning, and get a high level confidence passenger travel path selection results.This paper studies the Urban Rail Transit Path Simulation Subsystem, divide the subsystem to offline operation and online operation. At last use the Beijing Rail Transit as example, analysis the method feasibility in simulation system with experiment data.
