A road flow estimation method comprises the steps of classifying to-be-monitored roads according to road types, selecting one road from the to-be-monitored roads of each road type as a reference monitoring road, collecting the road average speed and the road traffic flow on each reference monitoring road, and estimating the road flow based on the road average speed and the road traffic flow. And establishing a single-lane vehicle flow density model, multiplying the single-lane vehicle flow density model by the model modification coefficient to obtain a vehicle flow density model of a to-be-monitored road belonging to the same road type as the reference monitoring road, and estimating the road flow of the to-be-monitored road by using the vehicle flow density model. Correspondingly, the invention further provides a road flow estimation device, electronic equipment and a storage medium. According to the method provided by the invention, estimation and prediction of the road traffic flow can be carried out with relatively low manpower and material resource costs, and relatively high accuracy is ensured.
