Abstract: A traffic signal interpretation system applied to a vehicle sets an action pattern of a vehicle with respect to a target area where a traffic signal is installed. Corresponding pattern information indicates a correspondence relationship between a lighting state of the traffic signal and the action pattern. Rule information indicates a rule that permits or prohibits a transition of the action pattern. The traffic signal interpretation system refers to the corresponding pattern information to acquire the action pattern corresponding to the lighting state as a provisional action pattern. When the provisional action pattern becomes one different from a previous action pattern, the traffic signal interpretation system sets a current action pattern by correcting a transition from the previous action pattern to the provisional action pattern so as to be consistent with the rule indicated by the rule information.

The system integrates, based on a traffic-signal-to-traffic-signal relational information, a forward traffic signal that is ahead of the travelling direction and that the vehicle should follow and a traffic signal correlated with the forward traffic signal in terms of the traffic signal display, among a plurality of recognized traffic signals. When there is an inconsistency in traffic signal displays identified between a plurality of integrated traffic signals, the system determines a first estimated traffic signal display of the forward traffic signal, based on the first evaluation value for each traffic signal.
