Provided are methods for automatically detecting traffic signals using sensor data. The methods can include obtaining first sensor data and second sensor data regarding an environment of an autonomous vehicle, where the first sensor data represents at least one image of the environment generated by at least one image sensor of the autonomous vehicle, where the second sensor data represents a three-dimensional point cloud associated with the environment, and where the second sensor data is generated by at least one range sensor of the autonomous vehicle. The method can also include determining a portion of the at least one image corresponding to a traffic signal in the environment, determining a point cluster of the point cloud corresponding to the portion of the at least one image, and determining a location of the traffic signal based on the point cluster. Systems and computer program products are also provided.
