Claim 0:
1. A method for classifying left turns of a vehicle, comprising:
receiving, by a processor of a mobile device, a sensor signal from a sensor residing in the mobile device while the vehicle is moving, where the signal is indicative of angular speed of the vehicle
constructing, by the processor, a feature vector from data received from the sensor;
training, by the processor, a classifier in part based on the feature vector, where the classifier outputs a probability that a left turn made by the vehicle is a protected left turn;
identifying, by the processor, one or more bumps in the sensor signal; and
classifying, by the processor, a left turn made by the vehicle as being a protected left turn based on number of bumps identified in the sensor signal, where the protected left turn has a traffic indicia which causes a time period assigned exclusively to making a left turn.
