DEEP LEARNING FOR ROAD CLASSIFICATION

Listening to road noise can be annoying. However, we can train machines to recognize the type of surface and the presence of wet in a glimpse from the tyre-road noise to make next-generation cars safer.

ROAD SURFACE DETECTION

Detecting the road roughness and wetness in intelligent vehicles allows to improve safety and sound quality inside the cabin.

WETNESS DETECTION

Being able to detect wet on the road allows to take safety measures in slippery conditions. We collected a large dataset of recordings from several microphone positions with wet and dry roads. We run CNN and BLSTM neural network on this corpus and obtain results as high as 95% and 97% respectively (F1-score).

SMOOTH/ROUGH CLASSIFICATION

The road roughness influence the grip and the rolling noise. Convolutional Neural Networks and a Siamese architecture allow high classification performance even without retraining the network on unseen tire types.
