Zusammenfassung:The invention discloses an on-ramp vehicle lane changing simulation model classification method and device based on trajectory data. The method comprises the following steps: acquiring microscopic car-following parameters of all vehicles at each moment; extracting a vehicle with a lane changing behavior, calculating a vehicle lane changing index corresponding to the time before and after lane changing according to the lane changing behavior of the vehicle, and calculating a lane changing index change ratio; manually marking a lane changing behavior category label, and determining a calculation formula of a classification decision function through the vehicle lane changing index corresponding to the lane changing behavior and the lane changing index change ratio; and determining a lane changing behavior category of the vehicle by utilizing the classification decision function, and further obtaining a vehicle lane changing simulation model classification result. According to the method provided by the invention
