Apparatus, program and storage medium for notifying intersection information

An intersection information notification apparatus for use in a vehicle comprising:

• a receiver for receiving information regarding a signal sequence of a traffic signal that is disposed at an intersection;
• and
• a notification unit for notifying the driver of the vehicle of transition of the signal sequence based on the information regarding the signal sequence under a circumstance that the vehicle is traveling toward the traffic signal in line with a signaling direction of the traffic signal.

An intersection information notification apparatus for use in a vehicle comprising:

• a memory medium that distinguishingly memorizes an attention-required traffic signal from other traffic signals, wherein the attention-required traffic signal is equipped with a first signal unit for signaling entrance and a second signal unit for signaling a turn, the second signal unit indicating no turn even after a signal change of the first signal unit from a first condition allowing entrance to a second condition not allowing entrance;
• and
• a warning unit for providing a warning that warns a driver of the vehicle of entrance into the intersection under a circumstance that (a) the vehicle is traveling toward the traffic signal in line with a signaling direction of the traffic signal, and (b) the traffic signal is determined as the attention-required signal based on information memorized in the memory medium

A computer program product comprising one or more computer readable media storing computer executable instructions that implement:

• a receiver for receiving information regarding a signal sequence of a traffic signal that is disposed at an intersection;
• and
• a warning unit for providing a warning that warns a driver of the vehicle of entrance into the intersection under a circumstance that (a) the vehicle is traveling toward the traffic signal in line with a signaling direction of the traffic signal, and (b) a current signal sequence of the traffic signal indicates that a current signal is allowing entrance into the intersection with a subsequent signal not allowing entrance into the intersection and not allowing a turn at the intersection.

A computer program product comprising one or more computer readable media storing computer executable instructions that implement:
