To enable a position to be detected with a high degree of accuracy without installing ground equipment even in a territory in which GNSS (Global Navigation Satellite System) information cannot be acquired.SOLUTION: A vehicle speed position detection device according to an embodiment is a vehicle speed position detection device mounted on a railway vehicle, and comprises: a position calculation part which calculates a position of the railway vehicle based on a travel distance and a position correction amount of the railway vehicle; a curve information holding part which is stored with curve information including a generating position of an extreme value of an angular acceleration or an extreme value of a curvature change rate in each curve section; and a position correction part which calculates the position correction amount on the basis of an actual generating position of the extreme value of the angular acceleration or the extreme value of the curvature change rate detected in the railway vehicle and a standard generating position of an extreme value of an angular acceleration or an extreme value of a curvature change rate of a curve during travel which is extracted with reference to the above curve information.SELECTED DRAWING: Figure 1
