PROBLEM TO BE SOLVED: To properly present an occupant with the easy-to-understand information on other vehicles approaching to an intersection. SOLUTION: Other vehicles approaching to the intersection continuously to some degree are grouped by a first grouping on the basis of an arrival time to the intersection and the difference in arrival times, and only one piece of information, in principle, on each group is represented by voice. On the other hand, other vehicles are grouped by a second grouping on the basis of only the approaching direction, and the information on the same is represented only by display. The unnecessary information on other vehicles is eliminated from the information on other vehicles to be represented, on the basis of a traveling condition of a self-vehicle and that of the other vehicles. Further an upper limit value of the number of groups is determined to prevent the complication caused by the information on the unnecessary groups. Further when a string of other vehicles approaching to the intersection is considerably long, the information that the group of other vehicles is continued from now on is additionally presented.
