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.
