A train running performance data driven running chart redundancy time layout acquisition method

Abstract

The invention belongs to the technical field of railway traffic, and relates to a train operation actual data driven running chart redundancy time layout acquisition method, which comprises the following steps: S1, extracting a late train operation record according to train operation actual data, and acquiring train late recovery time and influence factors thereof; S2, using a ridge regression model to obtain a ridge regression coefficient, namely an influence coefficient, of each influence factor; S3, determining an objective function of the redundant time layout optimization model accordingto the train late recovery time and the influence coefficient; S4, obtaining train operation constraint conditions according to the train operation diagram and the train operation limitation conditions; And S5, according to the train operation diagram and the train operation constraint conditions, solving the redundant time layout optimization model, and obtaining a redundant time layout scheme. The problems that in the prior art, support is difficult to provide for real-time scheduling and commanding, the scheme is not targeted, and recovery maximization of the late train cannot be achieved are solved.

Description

technical field [0001] The invention belongs to the technical field of railway traffic, and in particular relates to a method for obtaining redundant time layout of a running chart driven by actual train running performance data. Background technique [0002] The railway train operation diagram (hereinafter referred to as the train operation diagram) is a technical document used to indicate the train's operation in the railway section and the arrival, departure or passing time at the station, and is the basis for organizing the train operation of the whole railway. [0003] The procedures for specifying the section occupied by each train, the arrival and departure (or passing) time of the train at each station, the running time of the train in the section, the stop time of the train at the station, the route of the locomotive, the weight and length of the train, etc. It is an illustration of the train timetable, which stipulates that each train will run in the interval and a...

Problems solved by technology

[0005] In order to solve the above-mentioned problems existing in the prior art, the purpose of the present invention is to provide a method for obtaining the redundant time layout of the running chart driven by the actual train running performance data, and find the key stations and sections of the road network according to the train running delay data, that is, the redundant time utilization Sections and stations with a high rate of delays and high frequency of delays, and find key parameters that affect the efficiency of redundant time utilization. Based on this, further optimization of redundant time can be achieved, the robustness of the operation diagram can be enhanced, and it can be used to find out the advance time of each section and station. The assigned redundant time value enables each late train to be restored, which is used to solve the problems existing in the existing technology that it is difficult to provide support for real-time dispatching and command, the scheme is not targeted, and the late train cannot be restored to the maximum extent.
