Train operation scheme optimization compilation method and system

Abstract

The invention belongs to the technical field of urban rail transit. The existing train operation scheme is difficult to balance the operation cost and the service level. The invention provides a train operation scheme optimization compilation method. The method comprises the following steps: matching passenger flows of the same type according to the type of a compiled operation scheme to obtain a characteristic day passenger flow so as to perform time period division and time period attribute determination of the operation scheme; according to operation scheme time period division and time period attributes, determining the train operation frequency and the route crossing scheme in each time period by taking the plan-to-which-belongs route operation train ownership as a main constraint; determining turn-back and stop schemes of each time period according to the time-sharing train operation frequency and the traffic scheme and by considering the spatial and temporal distribution characteristics of the passenger flow of entering and exiting the station on the characteristic day; and according to the passenger flow imbalance of each transfer direction of the transfer station, determining a main transfer direction, and carrying out networked connection adjustment on the first and last buses of the operation scheme. Automatic compilation of operation schemes including multi-route, multi-marshalling and special driving organization modes is realized and supported.

Description

technical field [0001] The application belongs to the technical field of urban rail transit, and in particular relates to a method and system for optimizing a train operation plan. Background technique [0002] As an important technical document at the macro level of the urban rail transit organization, the train operation plan mainly stipulates the start and end time of operation, the frequency of train operation, the plan of train traffic, the plan of train stops, and the plan of train marshalling. Provide transportation services. [0003] With the continuous expansion of the urban rail transit network topology and the rapid growth of passenger flow, it is increasingly difficult for the extensive operation plan to meet the cost control of the subway operating company and the dynamic passenger flow demand, and the high operating cost and cost reduction of the subway have emerged.

Problems solved by technology

[0003] With the continuous expansion of the urban rail transit network topology and the rapid growth of passenger flow, it is increasingly difficult for the extensive operation plan to meet the cost control of the subway operating company and the dynamic passenger flow demand, and the high operating cost and cost reduction of the subway have emerged. There are a series of urgent problems to be solved, such as heavy efficiency-enhancing tasks, low level of automation, and poor adaptability of operation schemes.

[0004] In the actual transportation production process, the preparation of the train operation plan is heavily dependent on the historical experience of the operation planners, lack of scientific and effective operation plan preparation process and methods, and there is no detailed principle and basis for the decision-making of the train organization, so it is difficult to balance the operation cost and service level
