Abstract
A first processor derives a first arrival time to be taken for a vehicle and another vehicle travelling straight ahead to intersect at a point. A second processor derives a second arrival time to be taken for the vehicle and the other vehicle running on a straight line linking the vehicle and the other vehicle to encounter at a point. A third processor derives a first range of travelling directions the vehicle can take between the second arrival time and the first arrival time and derives a second range of travelling directions the other vehicle can take between the second arrival time and the first arrival time. A determiner determines relative relation between the vehicle and the other vehicle at a time of intersection between the vehicle and the other vehicle, based on difference between the first range and the second range.
