1. A map information generating system, comprising:
- a memory that stores map information including a road network; and
a controller that;
gathers traveling information including a plurality of loci, each locus representing a vehicle traveling along a road that is not included in the stored road network;
separates the loci within the gathered traveling information into groups, each group related to a same road, the loci being separated into the groups by the controller;
determining positional coordinates at predetermined distance intervals along each locus within the gathered traveling information;
calculating an average separation distance between respective positional coordinates as a separation distance between each locus in the gathered traveling information; and
grouping together the loci in the gathered traveling information in which the calculated separation distance is within a predetermined distance; and
generates new road information relating to a single new road for each group of loci.

Abstract
Systems, methods, and programs store map information including a road network. The systems, methods, and programs gather traveling information including a plurality of loci, each locus representing a vehicle traveling along a road that is not included in the stored road network. The systems, methods, and programs separate the loci within the gathered traveling information into groups, each group related to a same road and generate new road information relating to a single new road for each group of loci.

8. A map information generating method, comprising:
-
storing map information including a road network; gathering traveling information including a plurality of loci, each locus representing a vehicle traveling along a road that is not included in the stored road network; separating the loci within the gathered traveling information into groups, each group related to a same road, the loci being separated into the groups by; determining positional coordinates at predetermined distance intervals along each locus within the gathered traveling information; calculating an average separation distance between respective positional coordinates as a separation distance between each locus in the gathered traveling information; and grouping together the loci in the gathered traveling information in which the calculated separation distance is within a predetermined distance; and generating new road information relating to a single new road for each group of loci. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A computer-readable storage medium storing a computer program usable to generate map information, the computer program comprising:
-
instructions for gathering traveling information including a plurality of loci, each locus representing a vehicle traveling along a road that is not included in a stored road network; instructions for separating the loci within the gathered traveling information into groups, each group related to a same road, the loci being separated into the groups by; instructions for determining positional coordinates at predetermined distance intervals along each locus within the gathered traveling information; instructions for calculating an average separation distance between respective positional coordinates as a separation distance between each locus in the gathered traveling information; and instructions for grouping together the loci in the gathered traveling information in which the calculated separation distance is within a predetermined distance; and instructions for generating new road information relating to a single new road for each group of loci.
