Abstract: PROBLEM TO BE SOLVED: To provide a map difference data creation device capable of controlling the traffic transmitted to a vehicle and creating map difference data ensuring a road networkSOLUTION: When a map change requiring addition of roads "e" and "f" on a first version of a map data occurs, a map difference data delivery device reflects the addition of the roads "e" and "f" to the first version of the map data to create a second version of the map data After that, when a map change requiring addition of a road "g"-"i" on the second version of the map data occurs, the map difference data delivery device reflects the addition to the second version of the map data to create a third version of the map data The map difference data delivery device determines whether any dependent relationship is found between the addition of the roads "g"-"i" and the addition of the roads "e" and "f" When any dependent relationship is found, the map difference data delivery device creates a piece of map difference data including the addition of the roads "g" and "e"

TL;DR: In this paper, the connection relations of roads between adjacent areas are represented by allocating identical connection numbers to respective roads connected to each other between the adjacent areas, so that even when the identification number of a road connected to a road in another area is changed during update of the map data, the connection relation between roads connected between adjacent regions can be maintained by correcting the connection table and the updating operation can be completed without modifying map data in other areas at all.
