<P>PROBLEM TO BE SOLVED: To provide an information processor capable of accurately determining whether a vehicle is traveling on an elevated road or under the elevated road. <P>SOLUTION: A navigation 1 acquires a position of an own vehicle based on GPS information transmitted from a GPS receiver 2. Also, the navigation 1 acquires other vehicle position information and a GPS reception intensity signal for acquiring the other vehicle position information via an inter-vehicle communication device 4. Further, based on the acquired other vehicle position information and GPS reception intensity signal, the navigation device 1 acquires a three-dimensional position of another vehicle which indicates whether the other vehicle is traveling on an elevated road or under the elevated road. Thus, based on the position of the own vehicle and the three-dimensional position of the other vehicle, the navigation 1 determines a possibility of collision of the own vehicle and the other vehicle. <P>COPYRIGHT: (C)2012,JPO&INPIT |
