Map data update device
First Claim
1. A server apparatus comprising a map data update device configured to update map data on the basis of movement history data of a moving body, the server apparatus comprising:
- a movement history recording unit configured to cause movement history data relating to at least one moving body to be stored in a movement history storage unit, wherein the movement history data includes data of a traveling locus and data of a traveling speed of a vehicle; and
a road associated information setting unit configured to determine and set road associated information to be applied to a road link of a new road, on the basis of the movement history data stored in the movement history storage unit for a region where an existing road is not present on the map data;
wherein the road associated information setting unit is configured to specify a connection-source existing road and a connection-target existing road connected with the new road at both ends of the new road, and to determine and set a road type of the new road from among an expressway, a local road, and a ramp road as a piece of the road associated information, on the basis of road types set on the map data for the specified existing roads and traveling speeds of a plurality of vehicles indicated by movement history data relating to the new road.

Abstract
For a new road set in a region where an existing road is not present in map data, a road associated information setting unit 13 determines and sets road associated information to be applied to a road link of a new road on the basis of movement history data relating to a plurality of moving bodies stored in a movement history storage unit 14. Accordingly, the road associated information on the new road is automatically set on the basis of the movement history data relating to the plurality of moving bodies, and hence a worker is no longer required to execute on-site investigation or manually generate road associated information.

2. A server apparatus for updating map data on the basis of movement history data of a moving body, the server apparatus configured to:
-
store movement history data relating to at least one moving body in a non-volatile memory, wherein the movement history data includes data of a traveling locus and data of a traveling speed of a vehicle; and determine and set road associated information to be applied to a road link of a new road, on the basis of the movement history data stored in the non-volatile memory for a region where an existing road is not present on the map data; wherein the server apparatus is configured to specify a connection-source existing road and a connection-target existing road connected with the new road at both ends of the new road, and to determine and set a road type of the new road from among an expressway, a local road, and a ramp road as a piece of the road associated information, on the basis of road types set on the map data for the specified existing roads and traveling speeds of a plurality of vehicles indicated by movement history data relating to the new road.
