PROBLEM TO BE SOLVED: To provide a map matching device capable of specifying precisely a moving route on a DRM data, based on a probe data collected by a mobile terminal. SOLUTION: A control part 3 creates locally and collectively probe data divided into moving line units, and prepares integrated data. Then, the control part 3 calculates a moving direction of the integrated data, and searches candidate links of correlating the integrated data. Then, the control part 3 determines the nearest link having the direction nearest to the moving direction of the integrated data, out of the candidate links, and settles a foot of a perpendicular connecting position coordinates of the integrated data to the nearest link, as the nearest point. The control part 3 determines thereafter the links to be included in the moving route, one by one, using a set of the nearest points, and specifies the moving route. COPYRIGHT: (C)2009,JPO&INPIT |
