Abstract:
Systems and methods of detecting traffic light signal changes are disclosed. For instance, it can be determined that a user is stopped at an intersection having a traffic light. A plurality of images can be captured in response to detecting that the user is stopped at the intersection having a traffic light. The plurality of images do not depict the traffic light. A tonal shift in one or more color values associated with at least one image of the plurality of images can be detected. The tonal shift is indicative of a change in signal provided by the traffic light. A notification indicative of the change in signal provided by the traffic light can be provided to the user.
