The invention discloses an over-path traffic solving method for a completely-crowded large-scale public transportation network, and the method comprises the steps: obtaining a getting-on arc and a corresponding effective departure frequency through a first algorithm; the second algorithm calculates the use probability of passing through all the upper turning arcs under the super path, so that the complete upper turning arc flow distribution of the super path, the use probability vector of the upper turning arcs and the use probability vector upper turning arcs of the nodes are obtained; then, adopting column generation to construct an OD pair sub-problem, and determining the optimal transfer amount from a non-reference super path to a reference super path in the OD pair sub-problem through binary search; and the fourth algorithm obtains an over-path traffic equilibrium solution under the public transportation network equilibrium condition. Therefore, by setting the first algorithm, the second algorithm and the like, a complete algorithm capable of processing large-scale public transportation network distribution is constructed, so that the super path is constructed based on the effective departure frequency, and the method is suitable for practical application of the city-level large-scale public transportation network.

The invention discloses a bus network intelligent scheduling method based on a machine learning model, and belongs to the technical field of data processing, and the method comprises the following steps: receiving network sensing data, generating a network operation situation snapshot when detecting that the network sensing data has an abnormal evolution trend, and transmitting the snapshot to a scheduling information coordination processing unit, each scheduling information entry is generated; calling each scheduling information entry for overlapping detection, outputting an overlapping relation matrix, and dividing to obtain a normal scheduling information set and each conflict scheduling information set; machine learning model training parameters of all conflict scheduling information entries are obtained, a model historical stability index and a model generalization credibility index of a machine learning model are obtained through analysis, and all conflict scheduling execution instructions are obtained through screening according to the model historical stability index and the model generalization credibility index so as to execute public transit network intelligent scheduling. The technical problem that in the prior art, different scheduling information has deviation and inconsistency in the state cognition level is solved.
