Abstract
Device, system and method, in a vehicle communication system, of providing guidance, route and safety information to a driver. Embodiments use the observation and storage of signal light timing information to make recommendations. Embodiments include computation of future times of signal light changes. Embodiments use information relating to the number of vehicles, location of vehicles, and speed of vehicles in a plurality of lanes approaching a signal to recommend lane changes to a driver. Embodiments include receiving timing information wirelessly about signal timing. Embodiments include using historical information to compute a risk value for a location and then generating a recommendation to a driver responsive to that risk value. Embodiments include using speed of travel on route options to compute an expected travel time, and then generating a recommendation to a driver responsive to those computed travel times.
