The invention provides a variable speed limit group compliance prediction method based on section traffic flow parameters, and the method comprises the steps: inputting a to-be-detected traffic flow characteristic parameter matrix into a constructed driver group compliance prediction model based on a traffic flow characteristic parameter matrix, and obtaining a driver compliance level; the construction method of the driver group compliance prediction model based on the traffic flow characteristic parameter matrix comprises the steps that lane-level variable speed limit boards are arranged on a high-speed road at a first preset interval so as to display lane-level speed limit information; acquiring a training traffic flow characteristic parameter matrix; calculating and obtaining the compliance of the to-be-tested driver group; obtaining a grade compliance degree set; constructing a compliance original database; and based on an LGBM model, constructing a driver group compliance prediction model based on the traffic flow characteristic parameter matrix. The problems that in the prior art, speed limiting optimization cannot be conducted according to the compliance degree of a driver, and most of current roads do not have the vehicle track collection function are solved.
