  "textContent": "A road estimation device receives data including a core point (CP) being assigned along a road and being assigned with attributes including at least a shape-relevant attribute being relevant to a road shape for identifying the road. A map data input unit (13) inputs map data including links having attributes. A link narrowing down unit (S333-S336) sets a search area for the core point in a map and extracts links (L1-L4) in the search area from the map data, according to the attributes of the link and the shape-relevant attribute of the core point. The link narrowing down unit (S333-S336) further narrows down the extracted links (L1-L4) into a candidate link being candidate of the road represented by the core point (CP) for estimating the road on a map, according to parallel road information (PCI) being the shape-relevant attribute.",
