PROBLEM TO BE SOLVED: To provide a traffic information guiding device for, even when the position of an object intersection included in provided traffic information is expressed with general-purpose coordinate data, specifying the position of the object intersection on road network data, and for, even when the object intersections are a plurality of node intersections, appropriately determining the object intersection nodes in order to perform traffic information guidance. SOLUTION: This traffic information guiding device includes: a means for extracting one or more nodes positioned within a prescribed distance from the coordinates of an object intersection included in traffic information as a candidate node NB; a means for determining one object intersection node NA from one or more candidate nodes NB, and configured to, when a plurality of candidate nodes NB corresponding to one or more node intersections are extracted as for a plurality of node intersections where a plurality of nodes are set corresponding to one intersection, determining the candidate node NB reaching first when an own vehicle 3 travels along a road from a link K3 under traveling as an object intersection node NA.
