Target urban railway interconnection and intercommunication operation organization scheme optimization method

Abstract

The invention provides a target urban railway interconnection and intercommunication operation organization scheme optimization method, which considers a railway interconnection and intercommunicationoperation organization mode that achieves peripheral departure and central arrival, optimizes a national railway operation organization scheme in a target city range, and under given transportation lines and passenger flow demand conditions, constructs a high-speed railway operation organization scheme optimization model by taking full utilization of the passing capacities of stations and lines,taking convenient travel of passengers in a city as an optimization objective, and taking station capacity limitation, passenger flow space-time characteristics and line and section capacity limitation as constraint conditions, and finally solves the mixed integer programming model. According to the method, an operation organization scheme is optimized through modeling, so that the capacity utilization rate of a railway line network and a hub is fully exerted, distribution of access trains and stop trains of lines and stations with large capacity redundancy and lines and stations with insufficient capacity is reasonably adjusted, and an elastic space is reserved for long-term line planning.

AI Technical Summary

Problems solved by technology

[0005] First, the existing methods mostly model and optimize railway operation schemes from the perspectives of operational economic benefits, passenger travel costs, train delays, etc., and mainly conduct case tests on regional railway passages, and have not yet proposed the optimization of railway operation organizations in target cities method, there is no research on the optimization model of the operation organization plan for the capacity utilization rate of the urban railway network and the convenience of railway travel for passengers in the city

[0006] Second, the existing mixed integer optimization model considers constraints in the field of optimization of railway operation schemes, mainly weather, train schedule, travel time, etc., and does not take into account the impact of the railway interconnection operation organization model on railway capacity utilization and passenger service level. The possible impact, and use it to optimize the railway operation organization plan
