Road snow blowing early warning method, device and equipment and readable storage medium

The invention provides a road snow blowing early warning method, device and equipment and a readable storage medium, and relates to the technical field of road disaster prevention, and the method comprises the steps: constructing a criterion layer weight matrix based on the relative importance between criterion layers, and constructing a sub-criterion layer weight matrix based on the relative importance between sub-criterion layers; according to the criterion layer weight matrix and the sub-criterion layer weight matrix, calculating to obtain a weight of a wind-blown snow strength factor; the wind-blown snow monitoring data at the current moment are input into the prediction model, prediction data of a wind-blown snow intensity factor at the preset moment are obtained, and the time difference between the preset moment and the current moment is the first duration; the method is used for solving the problems that according to an existing early warning method, the requirement for cleaning and maintaining of a ca
