Recognition of snow condition using a convolutional neural network and control of road-heating systems

The conventional control method for road-heating systems, which is controlled mainly by snowfall, is the feedforward control. Therefore, the road-heating systems often operate in spite of no snow on the parking lots. In this paper, we introduce the method of feedback control for road-heating systems that detects snow condition on the parking lots, and turns road-heating systems on and off properly. To recognize the snow condition, we adopt images for recognition using convolutional neural networks.
