1. An apparatus comprising:
a camera for capturing an image wherein the image includes a representation of a leading vehicle;
a receiver configured to receive a traffic signal location and a traffic signal cycle state;
a processor configured to estimate a leading vehicle height and a leading vehicle width, a first distance between a host vehicle and the leading vehicle in response to the image, a second distance between the host vehicle and a traffic signal in response to the traffic signal location, estimating a traffic signal view obstruction in response to the leading vehicle height and the leading vehicle width, the first distance, and the second distance, and generating a graphical user interface in response to the traffic signal view obstruction;
a vehicle controller for reducing a host vehicle speed in response to the traffic signal view obstruction to ensure that at least a threshold distance is maintained between the host vehicle and the leading vehicle such that the traffic signal remains visible; and
a display configured to display the graphical user interface wherein the graphical user interface is indicative of the traffic signal cycle state.
