The present invention discloses a characteristic modes decomposition method for traffic volume based on generation-filtering mechanism, which includes: firstly, the expressway traffic flow is regarded as a closed traffic system. According to the randomness of drivers, each driver is regarded as a separate particle to simulate its trajectory, and then the corresponding traffic modes are obtained according to the probability distribution of the trajectory under different parameters; secondly, taking different parameters of the quantum walk, the time evolution of the probability distribution of the traffic volume caused by different driving patterns at a station is obtained, and then performing the same for other different stations to generate a set of expressway traffic mode set; and finally, according to observed traffic volume data, the generated traffic modes are screened to inverse the mode structures of traffic volume.
