Research On Urban Mass Transit Passenger Route Choice In The Condition Of Network Operation

With the accelerated progress of Urban Mass Transit system construction in some major cities, the operation management mode brings about a big change from dependent operation by line to network operation. As the foundation of network operation management, passenger flow is a key basis to ticket fare clearing, emergency command and operation scheme making. Due to the application of the AFC system in the One-Ticket transfer network, the OD data can be easily collected accurately, but the travel route of passengers can't be recorded clearly. So precisely in order to solve this problem, this paper studies on passenger travel routes choice in the network operation conditions.First of all, the paper analyses different kinds of factors influencing passengers' choice. Based on the crowds and the queuing time whiling transferring to another rail, the paper add other two factors, additional time of into or out stations and seat demand of long-distance passengers. Second, the paper for the first time put forward to classify passengers into two categories, familiar type and strange type. The paper analysis travel routes choice, and get a formula of comprehensive travel impedance. Third the paper introduces two algorithms, Deletion Algorithm and Bi-directional Search Algorithm. Then ratio correction method of multi-route distribution model is improved. Finally the paper uses passenger flow data and parameter which is from questionnaires to calculate passenger travel routes choice and get final calculation result, which verifies the above studies.
