<P>PROBLEM TO BE SOLVED: To provide a technology for performing effective radio propagation analysis, without influencing accuracy of analysis. <P>SOLUTION: A map data storing portion 11 stores information, and the like, including road information and the positions of obstacles as map data. An analysis area determining portion 12 determines an analysis area which is part of the map data and is targeted for radio propagation analysis, based on the road information stored in the map data storing portion 11 and the positions of a radio transmission vehicle and a radio reception vehicle. Then, a radio propagation analysis portion 13 performs radio propagation analysis, taking into consideration only the obstacles within the analysis area determined by the analysis area determining portion 13 and the obstacles adjacent to the analysis area, without taking into the other obstacles. <P>COPYRIGHT: (C)2009,JPO&INPIT |
