The invention discloses a device for rapidly detecting road dust emission factors. The device comprises a detection vehicle, a detection vehicle bottom dust accumulation load detection device, a detection vehicle internal positioning device, a remote data platform and a detection vehicle front road type detection device, an accumulated dust collection pipe is mounted at the bottom of the detection vehicle, the accumulated dust collection pipe comprises a collection device and an analysis device, road accumulated dust is rapidly collected and analyzed, collected data are transmitted to the remote data platform, the remote data platform obtains traffic flow and vehicle type distribution in the vehicle driving process and estimates the average vehicle weight, and road dust emission factors are calculated by combining a formula given by an AP-42 method. According to the invention, road dust is collected in an active dust collection mode, the vehicle flow and the average vehicle weight around the detection vehicle are obtained at the same time, the detection devices are reasonably arranged, the detection efficiency and accuracy are greatly improved, and the conditions of road dust emission factors of different road sections can be rapidly and efficiently calculated.
