Map matching system, map matching method and program |
摘要 |
Provided is a map matching device, method and program. The map matching device may comprise a road grid dividing unit and a grid road combining unit. The road grid dividing unit is for deriving a grid obtained by the division of a region where a road network exists in a latitude direction and a longitude direction by equal spaces and correlating the grid and an arc crossing the grid. The grid road combining unit is for assigning a common arc ID to a plurality of grids which are adjacent to each other and whose sets of arcs correlated are coincident and assigning an arc ID to a grid whose set of arcs correlated is different from a set of arcs of any of adjacent grids to generate information indicative of a relationship among a range of a grid, a grid ID and an arc passing the grid.
