The present invention discloses a method for fitting modes of a traffic flow based on a quantum walk, including: (1) constructing a mode generator based on the quantum walk; (2) preparing multiple modes; (3) screening the modes; and (4) constructing a mapping mechanism between the modes and the traffic volume. The present invention takes the expressway traffic flow as a complex geographic spatial-temporal process formed by aliasing and coupling of a plurality of traffic modes with different structures, and attempts to realize modeling and simulation of the traffic flow from a multi-scale analysis view. Specifically, under a basic framework of an expressway network topological structure, all possible traffic modes in the expressway traffic flow are generated using quantum walks; and under the constraints of the observed traffic volume time series, the modes are screened based on a specific screening rule.
