Classification: CPC G | IPC G

Claim 8:
9. A method for classifying left turns made by a vehicle, comprising:
receiving, by a processor, a plurality of feature vectors, where each feature vector is indicative of a left turn made by a vehicle and each feature vector includes geolocation of the vehicle during the left turn and time series data for the angular speed of the vehicle during the left turn;
spatially clustering, by the processor, the plurality of feature vectors based on geolocation to form one or more clusters of feature vectors;
assigning, by the processor, a ground truth to the one or more clusters; and
training, by the processor, a classifier with feature vectors in the one or more clusters using supervised learning, where the classifier outputs a probability that a left turn made by a vehicle is a protected left turn and a protected left turn has traffic indicia which creates a time period assigned exclusively to making a left turn.
