Intersection information supply apparatus

摘要

An intersection information supply apparatus includes a table indicating relationships between approaching directions of a vehicle to an intersection and signal forms, an approaching direction detecting unit detecting an approaching direction in which the vehicle is approaching the intersection, a transmission unit transmitting a signal having a signal form indicated in the table so as to correspond to the approaching direction detected by the approaching direction detecting unit, a signal obtaining unit selectively obtaining, from among signals externally arriving at the vehicle, a signal having a signal form indicated in the table so as to correspond to an approaching direction relevant to the approaching direction detected by the approaching direction detecting unit and an information output unit outputting information about presence of another vehicle when the signal obtaining unit obtains the signal.
